Portal tunnel - Portal is self-hosted tunneling relay to expose localhost

Portal is a self-hosted relay network. You can connect to any relay or run your own. Publishing a local service to the internet is often complicated. It usually requires opening inbound ports, configuring NAT or firewalls, managing DNS, and terminating TLS. Portal removes this complexity by inverting the connection model. Applications establish outbound connections to a relay, which exposes the service to the public internet and routes incoming traffic back to the application while preserving end-to-end TLS. Unlike other tunneling services, Portal is self-hosted and permissionless. You can run your own relay on your domain or connect to any relay.
