Core features
Built for real localhost publishing
Relay
Trustless relay transport
Relays own routing and transport, while the tunnel process owns endpoint behavior.
TLS
Client-side tenant TLS
Tenant TLS terminates locally with MITM detection, so relays cannot read plaintext.
HTTP
Tunnel-controlled HTTP routing
Mount frontend, API, and other local HTTP services behind one public URL.
Ports
Raw TCP and UDP leases
Expose game servers, custom TCP protocols, and datagram services through relay ports.
Mesh
Relay pools and multi-hop
Use discovered relays for failover or chain relays to split path visibility.
Ops
Self-hosted or public relays
Run your own relay, attach explicit relays, or use the public relay registry.
Quick Start
Expose service
Run this command
1. Paste what you want to share
A local port such as 3000, a running URL such as http://localhost:3000, or a file path such as file:///Users/me/site/index.html — file paths are served as a static site straight from that folder, so nothing needs to be running locally.
