The open-source challenger to Fivetran. A massive ecosystem of community connectors for long-tail APIs, but requires more day-to-day maintenance and babysitting.
De-facto standard of the transformation layer with a broad package landscape. Since 1 June 2026 dbt Labs belongs to Fivetran, so the transformation layer is no longer independent of the loading vendor.
5.0Best value
Over 750 sources and more than 200 destinations, including reverse ETL since the Census acquisition. Since the dbt Labs merger closed on 1 June 2026, the transformation layer belongs to the same vendor.
4.5Best value
Over 600 connectors, including long-tail ad platforms; the Starter tier covers 121 of them.
5.0Best value
A huge community connector landscape deep into the long tail.
Reliability
4.5Best value
Tests on every build catch silent data errors before they hit a dashboard.
4.5Best value
The managed heavyweight: pipelines run without babysitting.
4.5Best value
Managed pipelines that simply keep running.
3.0Best value
Community connectors vary in quality, plan for maintenance.
Value for money
4.5Best value
dbt Core is open source; costs only start with Cloud or orchestration.
3.0Best value
MAR-based pricing gets expensive at scale.
3.5Best value
From mid-size volumes the licence becomes a real line item.
4.5Best value
Open source and self-hosted, far cheaper than managed ELT.
Ease of use
3.5Best value
Assumes SQL and git discipline, otherwise the value stays on the table.
4.5Best value
Pick a connector, choose a destination, done.
4.5Best value
No-code harmonisation, marketing teams manage without engineering.
3.5Best value
Setup and upkeep need a team that runs pipelines.

When it fits
When SQL transformations should be versioned, tested and documented.
When you want a broad, managed connector portfolio and end-to-end data movement from one vendor.
When marketing data from many sources should flow harmonised into the warehouse.
When long-tail APIs need connecting and engineering capacity exists to run it.
When it does not
When there is only one report and nobody maintains SQL.
When only marketing data counts. Then a focused tool like funnel.io is leaner and cheaper.
When only two or three standard sources count; then native exports cost less.
When nobody wants to babysit pipelines; then Fivetran or funnel.io.
Every value comes from our individual reviews, scored against the review methodology. Prices without warranty, no paid placement.
Data integration connects source systems to the warehouse: ads platforms, shop, CRM, analytics. ETL tools replace what otherwise ends as a CSV export with copy-paste, using versioned, monitorable pipelines.
When this category matters
As soon as one report regularly needs data from more than one source. During any marketing-warehouse build anyway. And at the latest when an API update has silently broken a home-built pipeline for the third time.
Decision criteria
Connector coverage for your concrete sources, not the catalog length.
Cost model: by active rows, data volume, or self-operation.
Operating responsibility: managed SaaS or self-hosted with ops effort.
Transformation layer: loading raw data is not enough, models must be testable.
Fivetran is managed and gets expensive at high row volume; Airbyte is open source with a self-operation option. The real question is usually licence budget versus ops capacity.
Why does a pipeline need dbt on top?
Pipelines deliver raw data; dbt turns it into tested models with naming conventions, tests, and documentation. Without that layer, every dashboard becomes a one-off build.
