**APIs profiled:** 15

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.
