1. Introduction: The Open-Source ELT Challenger
I've spent over eight months running Airbyte across three different environments -- self-hosted on Docker, Kubernetes in production, and Airbyte Cloud -- and I can tell you that the open-source data integration landscape has fundamentally shifted since this tool entered the scene in 2020.
Before Airbyte, my team's data pipeline story was depressingly common. We paid Fivetran five figures annually for roughly 40 connectors, half of which broke during API changes and took weeks to get patched. We supplemented with custom Python scripts held together by cron jobs and hope. When I first heard about an open-source alternative with 400+ connectors, I was skeptical. Another open-source project that looks great in a README and falls apart in production? I had to find out.
My testing framework evaluates data integration tools across reliability, connector coverage, ease of deployment, cost efficiency, scalability, community health, and enterprise readiness. Airbyte scored surprisingly well in some areas and exposed real gaps in others. This review covers every honest detail from real production usage syncing over 50 million records monthly.
Pro Tip
If you're evaluating ELT tools, run a proof of concept with your actual data sources. Connector quality varies wildly depending on the specific API, and benchmarks mean nothing until you test your own workloads.
2. What is Airbyte? Understanding the Platform
\[VISUAL: Company timeline infographic showing Airbyte's growth from 2020 founding to present\]
Airbyte is an open-source data integration platform built for the modern ELT (Extract, Load, Transform) paradigm. Founded in 2020 by Michel Tricot (formerly engineering director at Liveramp) and John Lafleur (previously at Sqreen), the company set out to solve a problem every data team knows: getting data from point A to point B shouldn't cost a fortune or require an army of engineers.
The company has raised $181 million in funding from investors including Benchmark, Accel, and Y Combinator. That's serious backing for an open-source project and signals long-term viability that matters when you're betting your data infrastructure on a tool.
Airbyte's core philosophy differs from incumbents like [Fivetran](/reviews/fivetran) and Stitch. Rather than building every connector in-house, Airbyte created a Connector Development Kit (CDK) that enables anyone to build and contribute connectors. This community-driven approach is why the connector catalog exploded to 400+ sources and destinations in just a few years. The trade-off, which I'll cover extensively, is that connector quality varies depending on who built and maintains it.
The platform operates on the ELT model, meaning it extracts data from sources, loads it raw into your destination, and leaves transformation to tools like dbt. This separation of concerns is a deliberate architectural choice. Airbyte moves your data; dbt shapes it. In practice, this works beautifully for teams already using the modern data stack.
\[VISUAL: Architecture diagram showing Airbyte's extract-load flow with dbt transformation layer\]
Reality Check
Airbyte is not a full ETL platform. If you need complex in-flight transformations before data lands in your warehouse, you'll need additional tooling. Airbyte does one thing -- moving data -- and it does it well.
3. Airbyte Pricing & Plans: Complete Breakdown
\[VISUAL: Interactive pricing calculator widget - users input connector count and row volume\]
Airbyte's pricing model is one of its most compelling differentiators, but it also creates confusion. Let me break down each tier honestly.
3.1 Community (Open Source) - Truly Free
\[SCREENSHOT: Self-hosted Airbyte running on Docker with active syncs\]
The Community edition is fully open-source under the Elastic License v2 (ELv2). You can deploy it on your own infrastructure at zero software cost. This isn't a freemium trap -- it's the complete platform.
What's Included: All 400+ connectors, full sync capabilities, incremental and full refresh modes, change data capture, schema management, the Connector Development Kit, and API access. You get everything needed to run production data pipelines.
Key Limitations: No built-in RBAC or user management. No official SLA or guaranteed uptime. You manage infrastructure, upgrades, and monitoring yourself. No SSO or audit logs. Community support only via Slack and GitHub.
Best For
Data teams with DevOps capability who want maximum control and zero licensing costs. Startups watching every dollar. Teams comfortable managing Kubernetes or Docker deployments.
Hidden Costs
Infrastructure runs $200-800/month on AWS or GCP depending on volume. You'll spend engineering time on maintenance, upgrades, and troubleshooting. Budget 5-10 hours monthly for a healthy self-hosted deployment.
3.2 Cloud - Pay As You Go
\[SCREENSHOT: Airbyte Cloud billing dashboard showing credit usage and cost breakdown\]
Airbyte Cloud starts free with initial credits and charges based on usage. The credit-based model prices at approximately $1.50 per credit, where one credit roughly equals one hour of compute time for a sync.
Key Upgrades from Community: Fully managed infrastructure with 99.9% SLA. Built-in monitoring and alerting. Automatic connector updates. Basic user management. No infrastructure to maintain.
What You Still Don't Get: Advanced RBAC, SSO, audit logs, dedicated support, or custom SLAs. These are reserved for higher tiers.
Best For
Small to mid-size data teams wanting managed ELT without infrastructure overhead. Teams syncing moderate volumes who prefer operational simplicity over cost optimization.
Reality Check
Costs can surprise you. A single high-volume connector syncing hourly can burn through credits faster than expected. During testing, our 15-source setup cost roughly $400-600/month on Cloud versus $250/month self-hosted. Monitor your usage closely in the first month.
3.3 Team Plan ($60/month base) - Collaboration Features
The Team plan adds multi-user collaboration features that growing data teams need.
Major Additions: Role-based access control, multiple user seats, shared workspace management, priority email support, and enhanced monitoring. The $60/month base fee includes a set number of credits with additional credits at standard rates.
Best For
Data teams of 3-10 people who need access controls and don't want to self-host. Organizations where multiple analysts configure and monitor pipelines.
3.4 Enterprise (Custom Pricing) - Full Control
Enterprise pricing requires contacting sales. Expect significant premiums over Cloud pricing, negotiated based on volume and contract length.
Enterprise Exclusives: SSO/SAML authentication, advanced RBAC with custom roles, audit logging, dedicated Customer Success Manager, custom SLAs with guaranteed response times, private deployments, and premium support with phone access. HIPAA and SOC 2 compliance documentation available.
Best For
Large organizations with compliance requirements, teams needing guaranteed SLAs, and companies syncing enterprise-scale volumes across hundreds of connectors.
Pricing Comparison Table
\[VISUAL: Enhanced pricing comparison table with checkmarks and visual clarity\]
| Feature | Community (Free) | Cloud (Credits) | Team ($60/mo) | Enterprise |
|---|---|---|---|---|
| Connectors | 400+ | 400+ | 400+ | 400+ |
| Infrastructure | Self-managed | Fully managed | Fully managed | Managed/Private |
| User Management | None | Basic | RBAC | Advanced RBAC |
| SSO | No | No | No | Yes |
Caution
The credit-based pricing on Cloud makes cost prediction difficult. Run a two-week pilot to establish your baseline before committing to annual contracts.
4. Key Features Deep Dive
4.1 Connector Catalog - Breadth Over Depth
\[SCREENSHOT: Airbyte connector marketplace showing source and destination categories\]
Airbyte's 400+ connectors represent its biggest selling point and its most nuanced story. The catalog includes major sources like Salesforce, HubSpot, Stripe, Google Analytics, PostgreSQL, MySQL, MongoDB, and Shopify. Destinations cover the modern data stack essentials: Snowflake, BigQuery, Redshift, Databricks, and Postgres.
But not all connectors are created equal. Airbyte categorizes them by support level: Generally Available (GA), Beta, and Alpha. GA connectors are battle-tested and maintained by Airbyte's team. Beta connectors work but may have edge cases. Alpha connectors are experimental and community-contributed.
During my eight months of testing, GA connectors like PostgreSQL, Stripe, and Snowflake performed flawlessly. Our Salesforce connector handled complex object hierarchies without issues. But a community-built connector for a niche CRM broke twice during API changes and took weeks to get a community fix merged.
Pro Tip
Before committing to Airbyte for a specific source, check the connector's support level and GitHub issue history. A GA connector with active maintenance is production-ready. An Alpha connector with no recent commits is a gamble.
4.2 Incremental Sync & Change Data Capture
\[SCREENSHOT: Connection configuration showing sync mode selection with incremental options\]
Airbyte supports multiple sync modes that dramatically affect both cost and performance. Full Refresh overwrites all data each sync -- simple but expensive at scale. Incremental Append adds only new records since the last sync. Incremental Deduped History maintains a complete change history with deduplication.
Change Data Capture (CDC) for databases like PostgreSQL and MySQL reads the write-ahead log to capture every insert, update, and delete in real time. This is the gold standard for database replication, and Airbyte implements it well using Debezium under the hood.
Our PostgreSQL CDC setup captured changes across 40 tables with sub-minute latency. The initial snapshot of 20 million rows took about four hours, but subsequent incremental syncs completed in seconds. This alone replaced a fragile custom replication script that had been our biggest operational headache.
Best For
Teams replicating transactional databases where capturing every change matters for analytics accuracy.
4.3 Connector Development Kit (CDK) - Build Your Own
\[SCREENSHOT: CDK project structure showing a custom connector being built in Python\]
The CDK is what separates Airbyte from every commercial competitor. When Fivetran doesn't support your niche data source, you submit a request and wait months. With Airbyte's CDK, you build it yourself in hours.
The Python CDK provides base classes, authentication handlers, pagination logic, and schema management. You define your API endpoints, map the response to a schema, and Airbyte handles the rest -- scheduling, state management, error handling, and destination loading.
I built a custom connector for an internal API in about six hours. The CDK documentation walked me through the process step by step. A low-code CDK option using YAML configuration lets non-developers build connectors for simple REST APIs in under an hour.
Reality Check
Building is easy. Maintaining is the real cost. Every API change requires updating your custom connector. Budget ongoing engineering time if you rely on custom connectors in production.
4.4 Schema Management & Evolution
\[VISUAL: Diagram showing schema change detection and propagation flow\]
Schema changes are the silent killer of data pipelines. A source adds a column, renames a field, or changes a data type, and your pipeline breaks at 2 AM. Airbyte handles this better than most tools I've tested.
The platform automatically detects schema changes and offers three propagation modes: propagate all changes automatically, propagate only non-breaking changes, or require manual approval. During testing, Airbyte correctly detected and propagated 15 schema changes across our sources without a single pipeline failure.
Column selection lets you sync only the fields you need, reducing warehouse costs and sync times. When a source adds new columns, Airbyte notifies you and lets you choose whether to include them.
4.5 dbt Integration - Transform After Loading
\[SCREENSHOT: Airbyte connection settings showing dbt transformation configuration\]
Airbyte's native dbt integration completes the ELT workflow. After data lands in your warehouse, Airbyte can trigger dbt transformations automatically. This eliminates the need for a separate orchestrator just to run dbt after syncs complete.
The integration supports dbt Cloud and dbt Core. Configure your dbt project, map it to specific connections, and Airbyte runs your models after each successful sync. Our dbt models processed freshly loaded data within minutes of each sync completing, giving analysts access to transformed data faster than our previous orchestrated setup.
Pro Tip
Pair Airbyte's incremental syncs with dbt incremental models for maximum efficiency. Only process new data at every stage of the pipeline.
4.6 Monitoring & Observability
\[SCREENSHOT: Airbyte sync history showing success/failure rates and data volumes\]
Airbyte Cloud provides built-in monitoring with sync status, data volumes, error logs, and notification webhooks. Self-hosted deployments require more setup but expose metrics through standard tooling.
The sync history shows every run with detailed logs, record counts, and byte volumes. When a sync fails, error messages are generally helpful -- a significant improvement from the cryptic errors I remember from early versions. Webhook notifications integrate with Slack, PagerDuty, and custom endpoints for alerting.
On self-hosted, we configured Prometheus metrics and Grafana dashboards for deeper observability. Airbyte exposes connector-level metrics that helped us identify a slow Salesforce connector before it became a bottleneck.
5. Pros - What Airbyte Gets Right
\[VISUAL: Gradient-styled pros section with icons\]
Open-source transparency changes the game. When a connector breaks, you can read the source code, diagnose the issue, and submit a fix. During one incident, our Stripe connector silently dropped records with null timestamps. We traced the issue in the source code within an hour, submitted a PR, and had it merged within days. Try doing that with Fivetran.
The cost savings are real and dramatic. Our Fivetran bill was $2,800/month for 35 connectors. Self-hosted Airbyte with comparable coverage costs us roughly $300/month in infrastructure. Even Airbyte Cloud at $600/month represents a 78% savings. For startups and mid-size companies, this difference funds an additional data engineer.
Connector breadth enables consolidation. Before Airbyte, we used Fivetran for SaaS sources, custom scripts for databases, and Kafka Connect for event streams. Airbyte handles all three categories through a single interface. One tool to monitor, one team to maintain, one set of patterns to follow.
The CDK empowers self-sufficiency. Building custom connectors means you're never blocked waiting for a vendor to support your niche data source. This self-sufficiency is transformative for teams integrating proprietary or uncommon systems.
Community momentum is undeniable. With 15,000+ GitHub stars and an active Slack community of 20,000+ members, getting help is fast. Issues get responses within hours. The ecosystem of community-built connectors grows weekly.
6. Cons - Where Airbyte Falls Short
\[VISUAL: Gradient-styled cons section with warning icons\]
Connector quality is inconsistent. This is Airbyte's most significant weakness. GA connectors maintained by Airbyte's team are excellent. Community-contributed connectors range from production-ready to barely functional. We tested 12 community connectors; 3 had critical bugs, 4 had incomplete documentation, and 5 worked well. You must evaluate each connector individually.
Self-hosted operations require real engineering investment. Running Airbyte on Kubernetes is not for the faint-hearted. We encountered memory issues during large syncs, needed to tune worker configurations, and spent a full week debugging a persistent pod crash loop. Budget serious DevOps time if you choose the self-hosted path.
Cloud pricing is unpredictable. Credit-based pricing makes budgeting difficult. A connector that costs 2 credits today might cost 5 after a source API change slows pagination. Our monthly Cloud bill varied by 40% month-over-month with the same connector set. This unpredictability frustrates finance teams.
The UI feels utilitarian. Airbyte's web interface gets the job done but lacks the polish of Fivetran's dashboard. Connection configuration involves many screens. The sync history view buries useful information. Navigation isn't intuitive for non-technical users. This matters when you want analysts to self-serve.
Error handling needs improvement. When syncs fail, error messages are sometimes vague. "Connection refused" doesn't tell you whether the issue is network configuration, credential expiry, or source downtime. We spent hours diagnosing issues that better error messages would have resolved in minutes.
7. Getting Started & Setup Timeline
\[VISUAL: Setup timeline infographic showing phases from deployment to production\]
Getting Airbyte running depends entirely on your deployment choice. Here's what to realistically expect.
Airbyte Cloud (1-2 hours to first sync): Sign up, configure a source, pick a destination, and run your first sync. It genuinely takes under an hour for simple connections. The guided setup walks you through authentication and schema selection clearly. Most of our Cloud sources were production-ready within a day.
Self-Hosted Docker (4-8 hours): Clone the repo, run docker-compose up, and Airbyte starts. Initial configuration takes an hour. But production hardening -- setting up persistent storage, configuring SSL, establishing backups, and tuning memory -- adds a full day. We hit our first production-ready milestone on Docker in about two days.
Self-Hosted Kubernetes (1-2 weeks): Helm chart deployment is straightforward, but production tuning is not. Configure resource limits, set up horizontal pod autoscaling, establish monitoring, and build a deployment pipeline. Our Kubernetes deployment took 8 working days from start to stable production.
Caution
Don't underestimate the initial data backfill. Our first full sync of 50 million records across 15 sources took 36 hours. Plan your go-live around this initial load window.
8. Airbyte vs Competitors: Detailed Comparisons
\[VISUAL: Competitor logos arranged in comparison format\]
Airbyte vs Fivetran: Open Source vs Enterprise Polish
Fivetran is the incumbent champion -- polished, reliable, and expensive. Every connector is maintained by Fivetran's team with guaranteed SLAs. Setup is effortless. The UI is beautiful. Support is responsive.
But Fivetran's pricing model charges per Monthly Active Row, and costs escalate fast. Our 35-connector setup on Fivetran cost $2,800/month. The same workload on self-hosted Airbyte costs $300. Fivetran also locks you in -- no self-hosting, no custom connectors, no source code access.
Choose Fivetran if: Budget isn't a constraint, you need guaranteed reliability with zero ops overhead, and your connectors are all mainstream.
Choose Airbyte if: Cost matters, you need custom connectors, you want infrastructure control, or you value open-source flexibility.
Airbyte vs Meltano: Open-Source Siblings
Meltano is another open-source ELT tool built on the Singer ecosystem. It's CLI-first and code-driven, appealing to engineers who prefer configuration-as-code over GUIs.
Meltano has fewer connectors and a smaller community. The Singer tap ecosystem has quality issues similar to Airbyte's community connectors. Meltano's strength is its GitOps-friendly workflow and tighter dbt integration.
Choose Meltano if: You prefer CLI-driven workflows, want pure configuration-as-code, and have a small number of well-supported Singer taps.
Choose Airbyte if: You need more connectors, prefer a web UI, want CDC support, or need a managed cloud option.
Airbyte vs Stitch (by Talend): Legacy vs Modern
Stitch was an early managed ELT pioneer but has stagnated under Talend's ownership. Connector updates are slow. The platform feels dated. Pricing is row-based and expensive at scale.
Choose Stitch if: You're already invested in the Talend ecosystem and need minimal disruption.
Choose Airbyte if: You want active development, modern architecture, and better value at any scale.
Feature Comparison Table
| Feature | Airbyte | Fivetran | Meltano | Stitch |
|---|---|---|---|---|
| Connectors | 400+ | 300+ | 200+ (Singer) | 130+ |
| Open Source | Yes (ELv2) | No | Yes (MIT) | No |
| Self-Hosted Option | Yes | No | Yes | No |
| CDC Support | Yes | Yes | Limited | No |
9. Best Use Cases & Industries
\[VISUAL: Industry icons with use case highlights\]
Startups & Scale-ups - The Sweet Spot
Startups with 2-10 person data teams get the most value from Airbyte. Self-hosted Community edition costs nothing beyond infrastructure. The CDK handles niche integrations. And when you scale, upgrading to Cloud or Enterprise is seamless.
A Series B SaaS company I consulted replaced $3,200/month in Fivetran costs with self-hosted Airbyte managed by a single data engineer. They reinvested the savings into a BI tool upgrade.
Data Platform Teams - Infrastructure Control
Platform teams building internal data products appreciate Airbyte's infrastructure-level control. Deploy on your Kubernetes cluster, integrate with your CI/CD pipeline, manage configurations as code via the API, and monitor through your existing observability stack.
Consulting & Agencies - Multi-Client Flexibility
Data consultancies use Airbyte to serve clients without per-client licensing costs. Deploy isolated instances per client or use namespaced workspaces. The CDK builds custom integrations for client-specific systems.
10. Who Should NOT Use Airbyte
\[VISUAL: Warning/caution box design with clear indicators\]
Non-technical teams without engineering support. Self-hosted Airbyte requires real ops skills. Even Cloud Airbyte needs someone who understands data schemas, sync modes, and troubleshooting. If your team doesn't have a data engineer, choose Fivetran.
Organizations needing guaranteed uptime SLAs on day one. Self-hosted Community edition has no SLA. Cloud's 99.9% SLA is solid, but Enterprise-grade guarantees require the Enterprise plan. If a missed sync means regulatory violations, pay for Fivetran's proven reliability.
Teams needing only 5-10 mainstream connectors. If your integration needs are simple -- Salesforce, Stripe, and Google Analytics to BigQuery -- Airbyte's complexity isn't worth it. Fivetran or even native warehouse connectors handle this more cleanly.
Organizations with strict change management requirements. Airbyte's rapid release cadence means frequent updates. Self-hosted deployments need regular upgrades. If your change review process takes weeks, you'll constantly fall behind on versions.
11. Platform & Availability
| Platform | Availability |
|---|---|
| Web App (Cloud) | Full featured |
| Self-Hosted (Docker) | Full featured |
| Self-Hosted (Kubernetes) | Full featured |
| API / CLI | Full REST API, Terraform provider |
| Mobile App | Not available |
| Desktop App | Not available |
| OS Support (Self-Hosted) | Linux, macOS, Windows (Docker) |

| Data Residency | US and EU regions (Cloud) |
Pro Tip
Self-hosted deployments inherit your infrastructure's security posture. Running Airbyte in a private VPC with no public endpoints is more secure than any SaaS tool, but only if your team manages it properly.
13. Customer Support & Resources
Support Channels by Plan
| Plan | Channels | Response Time | Quality |
|---|---|---|---|
| Community | Slack, GitHub Issues | Hours to days | Community-driven, variable |
| Cloud | Email, Slack | 24-48 hours | Adequate for common issues |
| Team | Priority Email | 12-24 hours | Good, knowledgeable staff |
| Enterprise | Dedicated CSM, Phone | 1-4 hours (SLA) | Excellent, proactive |
The community Slack is genuinely helpful. Core team members actively answer questions. I've received useful responses within an hour on multiple occasions. GitHub issues get triaged quickly, though fixes for non-critical bugs can take weeks.
Official documentation has improved significantly since early versions but still has gaps for advanced deployment scenarios. The tutorial content covers basics well. For production hardening, expect to supplement with community blog posts and GitHub discussions.
14. Performance & Reliability
\[VISUAL: Performance metrics dashboard showing sync throughput\]
Sync throughput varies by connector type and deployment configuration. Our PostgreSQL CDC connector processes 10,000 records per second consistently. API-based connectors like Salesforce are bottlenecked by source API rate limits, typically syncing 500-2,000 records per second.
Self-hosted performance depends directly on your infrastructure allocation. We allocate 8 CPU cores and 16GB RAM per worker node on Kubernetes, which handles 15 concurrent syncs without issues. Under-provisioning causes sync failures and memory-related crashes -- the most common self-hosted problem I've encountered.
Airbyte Cloud performance is consistent and requires no tuning. Syncs generally complete 10-20% slower than our optimized self-hosted setup, but the zero-ops trade-off is worth it for most teams.
Reliability on Cloud has been excellent. We experienced two sync failures in eight months, both caused by source API outages rather than Airbyte issues. Self-hosted reliability depends entirely on your operations maturity.
15. Final Verdict & Recommendations
\[VISUAL: Final verdict summary with score breakdown\]
Overall Rating: 4.3/5
Airbyte has earned its position as the leading open-source data integration platform. The combination of 400+ connectors, genuine open-source availability, the CDK for custom connectors, and a viable managed cloud option creates a compelling package that no single competitor matches.
Best For: The Ideal Airbyte Users
Cost-conscious data teams save 60-80% compared to commercial alternatives while getting comparable connector coverage.
Engineering-forward organizations with DevOps capability extract maximum value from self-hosted deployments with full infrastructure control.
Teams with niche integration needs use the CDK to build exactly what they need instead of waiting on vendor roadmaps.
Modern data stack adopters already using dbt, Snowflake, or BigQuery find Airbyte slots perfectly into their architecture.
Not Recommended For: Who Should Look Elsewhere
Non-technical teams without engineering support should choose Fivetran for its managed simplicity.
Organizations needing only a handful of mainstream connectors don't benefit from Airbyte's breadth and complexity.
Teams requiring enterprise compliance from day one should evaluate whether Cloud Enterprise meets their specific requirements before committing.
ROI Assessment
\[VISUAL: ROI calculator showing cost comparison with commercial alternatives\]
Our concrete numbers: replacing Fivetran with self-hosted Airbyte saved $2,500/month ($30,000/year). We invested roughly 80 hours in initial setup and spend 8 hours monthly on maintenance. At a $100/hour engineering cost, first-year total cost of ownership was $17,600 versus $33,600 for Fivetran. The ROI was positive within five months.
Even on Airbyte Cloud, annual savings versus Fivetran exceeded $20,000 for our workload. The savings scale with connector count and data volume.
The Bottom Line
Airbyte isn't perfect. Connector quality is inconsistent, self-hosted operations require real investment, and the UI lacks polish. But for data teams willing to accept these trade-offs, the combination of open-source flexibility, massive connector coverage, and dramatic cost savings makes it the most compelling ELT platform available today.
Start with Airbyte Cloud for a risk-free evaluation. If the connectors you need work well, you've found your platform. If you have the engineering capacity, self-host for maximum savings and control. Either way, Airbyte has matured enough that it deserves serious consideration from every data team still paying premium prices for commercial ELT.

Frequently Asked Questions
Is Airbyte really free?▼
Yes, the Community edition is genuinely free open-source software under the Elastic License v2. You can self-host it on your own infrastructure with zero licensing costs. The only costs are your compute and storage infrastructure, typically $200-800/month depending on workload. Airbyte Cloud has a free tier with starter credits, but production usage requires paying for credits.
How does Airbyte compare to Fivetran on reliability?▼
Fivetran has the edge on reliability for mainstream connectors thanks to dedicated QA and enterprise SLAs. Airbyte's GA connectors are comparably reliable in my testing, but community connectors introduce variability. For mission-critical pipelines, evaluate each specific connector rather than making blanket comparisons. Airbyte Cloud's 99.9% SLA matches Fivetran's standard tier.
Can I run Airbyte in production on Docker, or do I need Kubernetes?▼
Docker works for small to medium deployments syncing fewer than 20 sources with moderate volumes. For anything larger, Kubernetes is strongly recommended. Docker deployments lack horizontal scaling, making them vulnerable during large backfills. Our Docker deployment handled 10 sources well but struggled when we scaled to 25.
How difficult is it to build a custom connector with the CDK?▼
For a standard REST API, expect 4-8 hours for your first connector and 1-2 hours for subsequent ones. The Python CDK provides base classes that handle pagination, authentication, and state management. A low-code YAML option handles simple APIs in under an hour. The learning curve is modest for anyone comfortable with Python.
