## About Windmill
Windmill is a self-hostable platform for APIs, background jobs, workflows and internal apps. Scripts in Python, TypeScript, Go, Bash, SQL, GraphQL, PowerShell, Rust and more become shareable UIs automatically and compose into flows or low-code apps, positioning it as an alternative to Retool, Pipedream and a simplified Temporal. The code is AGPLv3 and Apache-2.0, with proprietary enterprise features.
