Your first public URL

Prerequisites

You need a running local HTTP service, a Mac connected to the internet and an active trial or eligible Pro license. A public URL exposes your running development server. It is not a static file upload or permanent hosting service.

Create the connection

1. Open the service through its local address. Use sample data and check that administration pages are not unintentionally exposed.
2. Open a public URL for that domain. Choosing a name such as demo.localtr.dev depends on availability and server validation. Do not assume the name is reserved forever.
3. Add a password when appropriate. Test the link from another network, such as a mobile connection, before sending it.
4. Keep your Mac, LocalTR and local service running throughout the demo. Sleep or a network interruption can stop access.

Visitor → LocalTR relay → online Mac → local HTTP service

Scope

Each Mac has one simultaneous public tunnel. Opening another public connection replaces the current client. Multiple local domains do not mean multiple concurrent public tunnels. Bring-your-own domains, public WebSocket/SSE and general TCP/UDP are not supported promises for this release. The source defines a default 100 MiB public request body limit; validate large uploads in your environment.

Troubleshooting

If the service is unreachable, check localhost first, the tunnel state second and the external network third. Try a different subdomain if a name is refused. Reconnection attempts are bounded and are not an uninterrupted service guarantee. Close the link after the demo or pause it for new requests.
