What to look for

Six questions for any ETL tool.
And how Weld answers them.

  • Connectors you can rely on

    Does it cover your sources today, and who fixes a connector when an API changes?

    Weld: 300+ connectors, built and maintained in house, with log-based CDC for databases.

  • Transformations in the same place

    Can you model the data where it lands, or do you need a second tool?

    Weld: SQL models in your warehouse, or bring your own dbt, Cube or SQLMesh project.

  • Scheduling and orchestration

    Can loads and models run in order, on a schedule you control?

    Weld: Built-in orchestration that also runs dbt, Cube, SQLMesh and Coalesce.

  • Getting data back out

    Can the modelled data reach your CRM, ad platforms and spreadsheets?

    Weld: Reverse ETL is part of the platform, not a separate product to buy.

  • A price you can predict

    Is the price published, and what makes it go up?

    Weld: Every plan below Enterprise has a public price, set by Monthly Active Rows and connectors.

  • Security and ownership

    Does the data stay in a warehouse you own, under clear security terms?

    Weld: Data lands in your own warehouse, with SSO and 2FA on every plan.
