Windmill
Windmill is an open-source developer platform that turns scripts (Python, TypeScript, Go, Bash, SQL, and more) into internal tools, UIs, workflows, and cron jobs. It runs as Windmill Cloud (app.windmill.dev) or self-hosted, with a distributed worker fleet executing jobs. Everything in a workspace - scripts, flows, apps, schedules, variables, resources, triggers - is addressable over a single REST API (base https://app.windmill.dev/api on Cloud, or /api self-hosted), authenticated with a Bearer token, and is the same surface the Windmill CLI and web UI use.
Windmill publishes 15 APIs on the APIs.io network, including Apps API, Audit API, Flows API, and 12 more. Tagged areas include Developer Platform, Workflows, Internal Tools, Job Orchestration, and Cron.
Windmill’s developer surface includes authentication, engineering blog, documentation, and 8 more developer resources.
