Windmill

Code-first self-hosted job platform

Free tier + paidAutomation & background jobswindmill.dev

What it is

Open-source developer platform that turns TypeScript, Python, Go, Bash or SQL scripts into APIs, cron jobs, flows and auto-generated UIs. A Rust engine runs jobs fast with distributed dependency caching. Flows are a visual DAG layered on top of real, Git-versioned code files.

Why it earns a slot

The closest thing to self-hosted Retool plus Airflow plus cron in one deployment. Reach for it when you want scripts as the unit of work rather than nodes, and refuse to pay per execution forever.

Know before you commit

Dual AGPLv3 and Apache-2.0 source, but the published Docker images bundle proprietary enterprise code, so check which build you are running before redistributing. Enterprise pricing is seat plus compute-unit based and adds up quickly.

Getting started

docker compose up -d # windmill-labs/windmill compose file
