What is Windmill?

Open-source developer platform turning scripts into workflows, UIs, and webhooks. Self-host free or cloud from $8/month. Save $50K-200K vs Retool with 13x faster execution than Airflow.

Windmill eliminates the internal tool development bottleneck by transforming existing scripts into production-ready workflows, dashboards, and APIs. As an open-source alternative to Retool and Temporal, Windmill saves enterprises $50,000-200,000 annually while delivering 13x faster workflow execution than traditional orchestration tools.
