LocalPreview guide

Create a localhost tunnel for local development.

Create a localhost tunnel for local development servers, mobile testing, demos, and public previews without changing your app setup.

Tunnel

Expose a local port only when you need it

A localhost tunnel connects a public URL to a development server on your machine. LocalPreview keeps that path short: run your app, connect the port, and use the generated URL.

It is useful when another browser, phone, teammate, client, or service needs to reach work that only exists on localhost.

Local loop

Keep debugging and iteration on your machine

Use the tunnel for demos, responsive checks, webhook callbacks, and quick review sessions where a full preview deploy would slow you down.

Your app continues to run locally, so logs, errors, and request activity stay close to the editor where you are already working.
