ProxyHub
Tunnel, inspect & mock localhost - no backend needed
ProxyHub is the open-source way to expose localhost, inspect every request in real time, and mock any endpoint, no account, no backend, just one npx command. Built-in API testing tool, cURL export, mock server, and self-hostable for teams.
Hey Product Hunt 👋
I built ProxyHub because I kept juggling three tools whenever I worked on APIs — one to tunnel localhost, one to inspect traffic, and one to mock endpoints. So I rolled them into a single CLI.
npx proxyhub
That one command gives you:
- A public HTTPS tunnel to your localhost — no signup
- A real-time request inspector with filters, headers, bodies, and replay
- A built-in API testing tool to craft and send requests from the browser
- One-click cURL export for any captured request
- A mock server with a web UI — pure mock or hybrid with your real backend
- Token-protected tunnels and self-hosting via Docker
It's 100% open-source (MIT), no account required, and the server is a single container you can run
yourself.
Would love your feedback 🙏
