What is Windmill?
Developer platform that turns scripts into workflows, internal apps, cron jobs and AI agents.
Who is Windmill best for?
Windmill is best for engineering and data teams who turn scripts into self-hosted workflows, apps and cron jobs.
Engineering teams
Each script in Python, TypeScript, Go or another supported language gets an API endpoint and a form, and syncs with Git.
Long-running workflows
Flows have retries, approval steps and parallel branches, and can be drawn in the editor or written as code.
Internal tools
React or Svelte apps call your existing scripts and flows as their backend.
Data pipelines
DuckDB, Python and dbt steps run on your own workers, with each model tracked as an asset with its lineage.
