Fivetran Alternatives: 6 Tools Compared by Pricing Model (2026)
Fivetran is the reference managed ELT platform: 700+ connectors, log-based CDC for MySQL and PostgreSQL, zero infrastructure to run. The search for alternatives almost always starts at the bill: pricing is metered in Monthly Active Rows, so cost scales with how often your data changes — hard to predict for busy OLTP databases, and the free tier caps at 500k MAR. The second trigger is deployment: there is no fully self-hosted Fivetran.
Which alternative fits depends on which of those two triggers brought you here — and whether your sources are SaaS apps or databases.
Keep Fivetran if
- Your pipeline is dozens of SaaS apps into a warehouse and the MAR bill is acceptable.
- You want a fully hands-off managed service with enterprise SLAs.
- Connector breadth matters more than cost predictability.
1. DBConvert Streams
Best for self-hosted database replication at a flat price
If the Fivetran line-item that hurts is database sync — MySQL or PostgreSQL CDC metered per row — this is the direct fix: log-based CDC (binlog/WAL) delivered straight to the target database, files, or S3, self-hosted, priced per seat with no usage meters. A million rows and a hundred million rows cost the same. Initial load, validation, and monitoring are built in. It does not do SaaS connectors — it replaces the database half of a Fivetran bill, not the Salesforce half.
2. Airbyte
Closest like-for-like: big catalog, self-managed option
The most direct Fivetran substitute: a large connector catalog, warehouse destinations, and — the part Fivetran doesn’t offer — a free self-managed Core (source-available, ELv2). Cloud is volume-based from $10/month. Database CDC is Debezium-based.
3. Estuary Flow
Best published, predictable usage pricing
Managed CDC/ELT with pricing you can compute in your head: $0.50/GB moved + $100 per connector per month, free tier included. Per-GB is still a meter — but a more predictable one than MAR, because data volume is easier to estimate than row-change frequency.
4. Stitch
Best simple row-based entry point
A simpler managed ETL with published row-based tiers: from $100/month for 5–300M rows, 14-day trial. Same metered-pricing family as Fivetran, but with flat visible tiers instead of per-connection MAR math.
5. AWS DMS
Best for database migration into AWS
If the Fivetran use case was really "get my database into RDS/Aurora/Redshift", DMS does it with per-hour or serverless pricing inside your AWS account. Not a SaaS-connector platform at all.
6. Debezium
Best zero-license-cost option for engineering teams
Free (Apache 2.0) log-based CDC for databases — if you bring the Kafka/Connect infrastructure and the people to run it. The opposite trade from Fivetran: zero license spend, maximum ops.

| Airbyte | Self-managed / SaaS | Free core; volume cloud | Yes / Yes (Debezium) | ELv2 |
| Estuary Flow | SaaS | $0.50/GB + $100/connector | Yes / Yes | Commercial |
| Stitch | SaaS | From $100/mo (rows) | Incremental syncs | Proprietary |
| AWS DMS | AWS account | Instance-hours / DCU | Yes / Yes | Proprietary |
| Debezium | Self-hosted | Free | Yes / Yes | Apache 2.0 |
How to choose
- 1Bill driven by database row churn? Move the database pipelines to flat-priced self-hosted CDC (DBConvert Streams) and keep Fivetran for the SaaS connectors — the bills separate cleanly.
- 2Want the same shape, cheaper and self-manageable? Airbyte is the like-for-like swap.
- 3Want a meter you can predict? Estuary’s per-GB beats MAR for estimability; Stitch’s row tiers are at least visible up front.
- 4All-AWS? DMS. Engineering team with Kafka? Debezium.
Frequently asked questions
Why do teams leave Fivetran?
Two verifiable reasons dominate: MAR-based pricing that scales with row churn (hard to forecast for OLTP databases), and the absence of a fully self-hosted deployment. Feature complaints are rare — the platform is good; the model is what’s being shopped.
What is the cheapest Fivetran alternative?
For SaaS-connector ELT: Airbyte’s free self-managed Core, if you can run it. For database replication: DBConvert Streams at a flat $49/seat/month regardless of volume, or Debezium free if you already operate Kafka.
Can I replace just the database part of Fivetran?
Yes — that’s the highest-leverage split. Database CDC is usually the MAR-heaviest part of a Fivetran bill; moving MySQL/PostgreSQL replication to a flat-priced tool while keeping Fivetran for SaaS sources cuts the metered surface without a migration project.
