Frequently Asked Questions

Are they in the same category?

Partially. Windmill is broader (internal tools + workflows + scripts). 0nMCP is focused specifically on AI-native API orchestration via MCP. They overlap on workflow automation.

Which license is better?

For commercial use, 0nMCP's MIT license is more permissive. Windmill's AGPLv3 requires sharing modifications if you offer it as a service.

Can I use both?

Yes. Windmill can orchestrate 0nMCP via its HTTP server, combining Windmill's scheduling and UI capabilities with 0nMCP's AI-native tool orchestration.
