Full REST API

Every operation in Windmill is available through a JSON REST API. No SDK required — use curl, fetch, or any HTTP client.

What Windmill replaces

The overhead of managing pipelines tends to grow quietly until someone asks why the team is paying four different subscriptions for overlapping features. Windmill replaces that stack with a single process that starts in under a second.

Run Windmill on any server where you can execute a binary. The dashboard is immediately available at localhost, and the REST API integrates with your existing scripts and workflows. No external dependencies to configure, no managed service to subscribe to.

How it works

Start Windmill with a port and a data directory. It creates its SQLite database on first run and serves both the API and the dashboard on the same port. Create pipelines through the web interface or POST JSON to the API. Filter by source, destination, or search by keyword. Update records with PUT, delete with DELETE. The stats endpoint returns aggregate counts grouped by status for monitoring.
