About Windmill

Windmill is an open-source developer platform for scripts, workflows and internal tools, built by Windmill Labs, a startup founded by Ruben Fiszel. Its premise is that most internal automation starts as a script: you write code in Python, TypeScript, Go, Bash, SQL, PHP or other languages, and Windmill turns it into a shareable job with an auto-generated UI, permissions, logs and an API endpoint.

Scripts can be chained into flows with branches, loops, retries, approvals and error handlers, triggered by schedules, webhooks, HTTP routes, emails or message queues. An app builder creates dashboards and admin panels on top of those scripts, and a web IDE with dependency management and AI assistance speeds up development, while a CLI and git sync let teams manage everything as code. The execution engine is designed for low overhead and high throughput, which makes Windmill viable for data pipelines and background jobs. The Community edition is free to self-host; the cloud Team plan is priced per user plus compute, and Enterprise adds SSO, audit logs, SLAs and scaling features.

Windmill suits engineering and data teams that want one platform to replace a mix of cron jobs, Airflow DAGs and Retool apps. It is code-first, so non-technical users will prefer Zapier, Make or n8n, and its community is smaller than older tools. Airflow and Prefect remain more common for large data orchestration, Retool is more mature for complex UIs, and Temporal is better for long-running, durable application workflows.
