How to share a local web app online

A local build is useful for iteration, but reviewers still need a reachable URL. A Public Tunnel can bridge that gap before a full deployment exists.

Local buildThe app keeps running on your machine while you work.
Public URLA tunnel gives reviewers one stable link to open.
Faster reviewPeople can click through a real experience instead of watching a screen share.

When this helps

  • Client demos
  • Design reviews
  • QA previews
  • Temporary docs or landing pages

Simple decision path

  1. Need permanence?If yes, deploy it normally.
  2. Need a temporary preview?If yes, a tunnel is a faster fit.
  3. Need private review?Add authentication in the app before sharing sensitive content.
