Windmill
Open-source developer platform for scripts and workflows
Windmill turns scripts into workflows, UIs, and scheduled jobs. Write in TypeScript, Python, Go, or SQL and get auto-generated UIs with approval flows.
Panel Reviews
The Builder
Developer Perspective
“Scripts become workflows with auto-generated UIs. The approval flows and scheduling turn scripts into proper automation.”
The Skeptic
Reality Check
“Open-source Retool + n8n hybrid. The auto-generated UI from script parameters is surprisingly useful.”
The Futurist
Big Picture
“Internal tooling from scripts with auto-generated UIs is the right abstraction for developer-built automation.”
Community Sentiment
“Windmill is what Retool should have been — code-first with auto-generated UIs that don't get in the way”
“Replaced our internal n8n + custom cron scripts with Windmill. The approval flow feature alone saved us hours”
“Write a TypeScript function, get a production workflow with a UI in minutes. Windmill is seriously underrated”
“The multi-language support is killer — our team writes Python, TS, and SQL scripts and they all compose together”
