Windmill

What is Windmill?

Windmill takes a script in Python, TypeScript, Go or Bash and turns it into a versioned job with a generated UI, an API endpoint and a schedule, without you writing any glue. It is designed for developers who already have scripts and want them to be self-service for the rest of the team rather than locked in someone's terminal.
