Windmill
Code-first orchestration platform for internal software
Windmill is an open-source, code-first platform for building and running internal scripts, workflows, apps, AI agents, and data pipelines. It addresses the need to create internal software with full code flexibility while keeping execution, scheduling, and infrastructure management in one place. Scripts written in more than 20 languages can be turned into API endpoints and forms, with imports resolved and versions locked at each deploy. The platform can be self-hosted with Docker or Kubernetes, or used through Windmill Cloud.
Core capabilities include workflows, internal apps, data pipelines, and AI agents, with integrations for services such as GitHub, Slack, Stripe, Supabase, S3, OpenAI, and Google Sheets. Development can happen in the Windmill UI or locally via the Windmill CLI and MCP, with AI-assisted building available in the UI. The platform provides run observability with inputs, logs, results, traces, and metrics, plus Git-based collaboration with workspace forks, review workflows, and deployment to staging and production. It supports SAML/SCIM, audit logs, Git sync, and dedicated workers in its Enterprise edition.
Windmill is aimed at engineering and platform teams building internal tools and automations. It is available as a free, open-source Community Edition under AGPLv3 with unlimited executions and a limited number of users, and as a paid Enterprise edition with additional security, governance, and support features. Pricing is based on seats for developers and operators, with app guests and compute units billed separately.
