What is Windmill?
Windmill is an open-source, self-hostable platform for workflows, apps and AI agents. Its README says scripts become shareable UIs, APIs and cron jobs and can be combined into flows and data pipelines, with support for languages including Python, TypeScript, Go, Bash and SQL. Self-hosting uses Docker Compose or Kubernetes. Most of the code is open source, but its licence file says some enterprise features are proprietary and paid.

Pros: what Windmill does well
- Turns a script into a button, a form or a scheduled job
- Works with many programming languages
- Can be hosted on your own servers
Cons: where it falls short
- Aimed at people who can write code
- Self-hosting takes setup effort
Who Windmill is for

Who can skip it
