## How to choose a sql transformation tool

* Choose dbt for the largest package ecosystem and the format most data hires already know. dbt Core is open source; the dbt platform is priced per developer seat.
* Choose SQLMesh for development environments that don’t copy tables, and for checks on your SQL before it runs. It is Apache 2.0 and can read dbt projects.
* Choose Dataform if you are all-in on BigQuery. It has no licence fee; you pay for the BigQuery queries it runs.
* Choose Coalesce when part of the team would rather build models in a visual editor that still writes plain SQL.
* None of these move data into the warehouse. Pair them with an ETL or CDC tool.
