Score: 5.8/10 (Innovation: 5, Technical: 6, Documentation: 6, Utility: 6)

Tunr is a Go-based CLI tool that creates secure HTTPS tunnels to expose local development servers to the internet in seconds, positioning itself as an open-source alternative to ngrok and Cloudflare Tunnel. Its interesting features include demo superpowers like freeze mode and read-only proxies, plus support for TCP/UDP/TLS tunnels and MCP integration. The project is well-polished with extensive command options and cross-platform support, though its core concept is not radically new.

Target audience: backend devs, frontend devs, full-stack devs
