GitHub – Self-hosted tunneling relay to expose localhost

Summary: Portal is a self-hosted relay network that exposes local services to the internet by inverting connection models, enabling outbound connections to relays that route traffic back securely with end-to-end TLS.

What it does

Portal allows applications to connect outbound to relays, which then expose local services publicly and route incoming traffic back while preserving TLS encryption.

Who it's for

Developers needing to publish local services without configuring inbound ports, NAT, firewalls, or DNS.

Why it matters

It simplifies exposing localhost by removing complex network configurations and enabling permissionless, self-hosted relays.
