What is tnnl?

tnnl is a Rust single-binary tool to expose localhost to the internet, like a self-hosted ngrok without accounts. Fire up `tnnl http 3000` against the free public server at tnnl.run, and snag a random subdomain like abc123.tnnl.run forwarding to your local port. It handles HTTP routing by Host header over multiplexed TCP, perfect for quick webhook tests or sharing dev servers.

Why is it gaining traction?

No signup beats ngrok's barriers, plus free HTTP basic auth on tunnels (ngrok charges) and inspect mode dumping full headers/bodies with JSON pretty-printing. Replay captured requests by ID even after restarts, subdomain pinning via config file, and exponential-backoff reconnects keep it reliable. Self-hosting on a VPS needs one command, dodging frp's YAML sprawl or bore's port-only limits.

Who should use this?

Webhook wranglers debugging Stripe or GitHub payloads without ngrok quotas. DevOps exposing localhost to Docker containers or local networks for QA handoffs. Frontend devs ditching SSH tunnels to share localhost to internet free, or VSCode users needing expose localhost to internet Cloudflare-style without setup.

Verdict

Solid early pick at 12 stars and 1.0% credibility—mature enough for daily webhook drills, with crisp docs and install script. Skip for high-traffic; try the public server first, self-host for control.
