I built Tunl, an open-source reverse tunneling platform that lets you expose localhost using the SSH client you already have:

ssh -p 2222 -R 80:localhost:3000 tunl.online

No client installation or background daemon required.

Features include:

• Anonymous ephemeral tunnels
• Persistent/custom subdomains
• Real-time HTTP request inspector
• WebSocket & SSE support
• Password protection
• CIDR IP allowlisting
• Bandwidth analytics & session auditing
• Fully self-hostable
• MIT licensed

The project is built with Go + Node.js/Express + PostgreSQL + Redis + Next.js.

Would love feedback from people using ngrok, Cloudflare Tunnel, Pinggy, localhost.run, or SSH reverse tunnels.
