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 🙏

Just used this and its surprisingly simple and clean. The fact that its free makes it perfect for testing webhooks and local development workflows. 👍

This looks solid. I’ve been using a mix of Postman and local tunnels for a while, but having it all in a single CLI tool sounds way cleaner. Love the one-click cURL export too. Upvoted!
