## level 4: agent integration

Windmill is an open-source workflow engine designed for building internal tools, data pipelines, and automated workflows. It allows developers and AI to create and deploy these tools at scale, turning scripts into auto-generated UIs, APIs, and scheduled jobs. Windmill is self-hostable and emphasizes enterprise-level security.
