Working offline

How to keep DevToolery available without a network connection.

Once a page has loaded, its tool keeps working offline — the code is already in your browser.

Installing as an app

  • In Chrome or Edge, use the install icon in the address bar.
  • In Safari on iOS, use Share then Add to Home Screen.
  • On Android, use Add to Home screen from the browser menu.

What works offline

Every tool you have visited, plus the shell of the app. Pages you have never opened may not be cached yet, so it is worth visiting the ones you rely on at least once while connected.

What does not

Nothing needs the network to function, because no tool makes a request. The only limitation is loading a page whose code has not been cached.
