Windmill
Open source developer platform. Turn scripts into workflows and UIs.
What it is
Windmill is an open source developer platform. Write a script in Python/TypeScript/Go/Bash/SQL, and Windmill turns it into a workflow, scheduled job, API endpoint, or full UI (with forms and tables). Self-hostable, with a generous cloud free tier.
Why we recommend it
If you want to build internal tools without writing boilerplate (CRUD, auth, scheduling, UI), Windmill is the answer. The script-as-source model is a developer favorite, and the UI builder is excellent.
When to use it
- Internal tools for engineering teams
- Scripts that need a UI, schedule, or API
- Replacing a collection of cron jobs
- When you want a developer-first Retool
Quickstart
Run this in your terminal. Self-hosts locally with Docker or your preferred setup.
