A ngrok-style secure tunnel server written in Rust and Open Source

We hit this exact problem bridging n8n Cloud to a local Ollama instance on a Mac Mini. Tried Cloudflare tunnels (502 errors), bore-cli (random ports on restart — unusable with multiple HTTP nodes), and ngrok (requires auth/signup).

Ended up on localtunnel with a fixed subdomain and keepalive script. It works but drops connections and requires a bypass-tunnel-reminder header on every request.

Key requirements for this use case: fixed/predictable URL so downstream services don't need reconfiguration, low latency for API calls, and auto-reconnect as a daemon. Would be interested to try Rustunnel if it supports fixed subdomains.

Hey! it does support subdomains. Either by passing a flag --subdomain or just configuring them straight up in you config.yml file.

We also implemented auto-reconnect.

For now we only running servers in Europe, but we are implementing multi-region right now and should have it up in a couple of days. That should cut latency way down for people that not in Europe.
