windmill
windmill is an agent framework - Code-first platform for workflows, apps and AI agents, on the fastest self-hostable orchestrator (benchmarked against Airflow, Prefect and Temporal). Business teams build with AI, engineers control what ships. Open-source alternative to Lovable, Retool and n8n.
Overview
Open-source, self-hostable code-first platform for workflows, apps and AI agents, running on the fastest self-hostable orchestrator. Engineers write code in 20+ languages and sync it with Git. Business teams build on the same platform with AI, while review, promotion between environments and isolated workers keep engineers in control of what ships. Self-hostable alternative to Lovable, Retool, n8n and a simplified Temporal.
Scripts are turned into sharable UIs, APIs and cron jobs automatically, and can be composed together into flows, data pipelines, AI agents or full-code React and Svelte apps. Supported languages: Python, TypeScript, Go, Bash, SQL, GraphQL, PowerShell, Rust, and more.
Windmill is fully open-sourced (AGPLv3) and Windmill Labs offers dedicated instances and commercial support and licenses.

Business teams and engineers build on the same Windmill instance. What the AI builds is an ordinary script, flow or app, and goes through the same review as code written by engineers:
windmill is open-source, written primarily in Rust, with 18,330 GitHub stars under the Other license. The latest release is v1.849.0 (2026-10-25).
