How do I move off Fivetran to cut cost?
Fivetran is a managed ELT service priced per row. Moving to Bruin to cut cost works because Bruin's ingestion and transformation are open source with no per-row or per-seat fee, so the bill becomes warehouse compute. Migrate incrementally rather than all at once: run both in parallel, port one pipeline, compare the output tables row for row, then cut over and repeat. Compare total cost honestly: if your volumes are low, a managed service's convenience may be worth more than the licence saving.

Bruin CLI + your existing warehouse
What you get
How to do it
- 1
Inventory what Fivetran actually runs today, including the jobs nobody owns.
- 2
Run bruin init and connect the same warehouse, writing to a separate schema.
- 3
Port one low-risk pipeline first. Use bruin import where it can read your existing definitions.
- 4
Run Bruin and Fivetran in parallel and diff the output tables row for row.
- 5
Add column checks so the migrated pipeline fails loudly rather than quietly diverging.
- 6
Cut over that one pipeline, then repeat. Decommission Fivetran only when nothing references it.
How it works in code
$ bruin init my-project
$ bruin import # bring existing assets in
$ bruin validate ./pipeline
$ bruin run ./pipelineRun bruin run and you can compare Bruin's output against Fivetran's before cutting over.
Worth knowing
Do not big-bang a Fivetran migration. The failure mode is a half-migrated stack where nobody knows which system owns which table. Port one pipeline, verify parity, cut over, repeat.
Other ways to do this
Bruin is not always the right answer. Here is where the alternatives are stronger.
| Option | When it is the better choice |
|---|---|
| Bruin | A practical path off Fivetran when the goal is to cut cost, including what to verify before cutting over. |
| Stay on Fivetran | Often the right answer. If Fivetran works and the pain is theoretical, migration cost usually exceeds the benefit. |
| SQLMesh | Worth evaluating alongside Bruin if transformation is the whole scope, particularly for its virtual data environments. |
| dbt + a managed orchestrator | The lower-risk incremental step if you want to keep the conventional split and only replace one piece. |
Common questions
How do I migrate off Fivetran?
Incrementally. Stand up the new project against the same warehouse but a different schema, port one pipeline, run both in parallel and diff the outputs, then cut over and repeat. Decommission Fivetran last.
Will moving off Fivetran cut cost?
It can, because Bruin's ingestion and transformation are open source with no per-row or per-seat fee, so the bill becomes warehouse compute. Compare total cost honestly: if your volumes are low, a managed service's convenience may be worth more than the licence saving.
What is the biggest risk migrating from Fivetran?
Silent divergence. Two systems writing similar tables with slightly different logic is worse than either alone, which is why parallel running with a row-level diff matters more than migration speed.
Migrate incrementally, not all at once
Open source. Run both stacks in parallel, verify parity, then cut over.
