Windmill
Open-source platform for scripts, workflows and internal apps
What is Windmill?
Windmill is an open-source, code-first platform for building internal workflows, apps, AI agents and data pipelines. A script written in TypeScript, Python, Go, SQL or one of more than 20 languages becomes an API endpoint with a generated form, and scripts chain into flows with retries, approval steps and parallel branches. It can be self-hosted with Docker or Kubernetes or used as Windmill Cloud, and paid plans are priced by seats and compute units.
Windmill has a free plan. Paid plans start at $10 per seat / month (Cloud Team); self-hosted Pro from $48 / month. See every plan
Good for
- Engineering teams that want internal tools and automations kept as code
- Organizations that must run workflows on their own infrastructure
- Replacing scattered cron jobs and scripts with one orchestrated platform
Worth knowing
- Windmill is code-first: scripts and most flow steps are written in a programming language, so it suits engineers more than non-technical users.
- The free self-hosted edition stops at 3 workspaces, 50 users and 10 SSO users, has no audit logs and keeps run details for up to 30 days.
- Cloud Free covers 1,000 executions a month, and an execution is one job of under a second; each extra second of compute counts as another.
- Enterprise and Pro bill at least 2 compute units, and their instances report seat and memory use to Windmill through license telemetry.
Key features
- Scripts in more than 20 languages
- A function in TypeScript, Python, Go, Rust, Bash, SQL, PHP or another supported language becomes an API endpoint and a form. Imports are resolved and versions locked at each deploy.
- Workflows as a graph or as code
- Flows are drawn in a flow editor or written in Python or TypeScript and called as an API endpoint. Retries, approval steps and parallel branches are built in.
- Internal apps
- An app is a React or Svelte frontend whose backend is your existing scripts and workflows. It can be shared with teams, published publicly or embedded in another product.
- AI agents and AI-assisted building
- Agents run on any of 12 model providers or your own OpenAI-compatible endpoint, with scripts and MCP servers as their tools. Scripts and flows can also be generated with AI in the UI.
- Forks, review and rollback
- Changes are made in a fork of the workspace, reviewed as a diff, then deployed to staging and production. Each deployment keeps its version, so an earlier one can be redeployed.
- Run history and observability
- Every run keeps its inputs, logs and result, and a failure can alert a team on Slack, Teams or by email. Enterprise adds audit logs, queue metrics and OpenTelemetry tracing.
