The open-source tunnel that scales with you. Don't pay for idle time. Secure, Rust-fast, and Pay-as-you-go.
Expose local services through a public server over encrypted WebSocket connections with TLS termination, HTTP/TCP proxying, a live dashboard, Prometheus metrics, and audit logging.
You can self-host or use our managed service.
Using an AI agent? rustunnel ships an MCP server — one-click setup for Cursor (then add your API token):
For Claude Code, Claude Desktop, Windsurf, and others, see the agent integration guide or the agent manual at rustunnel.com/agents.md.

Hosted service
You can use rustunnel without running your own server. We operate a global fleet of public edge servers that you can connect to immediately.
Available regions
| Region ID | Server | Location | Control plane | Status |
|---|---|---|---|---|
eu |
eu.edge.rustunnel.com |
Helsinki, FI | :4040 |
Live |
us |
us.edge.rustunnel.com |
Hillsboro, OR | :4040 |
Live |
ap |
ap.edge.rustunnel.com |
Singapore | :4040 |

The client auto-selects the nearest region by default. Use --region <id> to connect to a specific one. The legacy address edge.rustunnel.com is a CNAME to eu.edge.rustunnel.com and will continue to work for backward compatibility.
