Web App Manifest (webmanifest)

A web app manifest is a JSON file (often named manifest.webmanifest) that enables Progressive Web App (PWA) features. It contains metadata like app name, icons, theme colors and start URL.

This allows websites to be installed to home screens, work offline, and feel like native apps.

It should not be confused with the manifest file for browser extensions.

Example content:

{
  "name": "My PWA App",
  "short_name": "PWApp",
  "description": "A Progressive Web App.",
  "icons": [...],
  "screenshots": [...],
  "start_url": "/",
  "display": "standalone",
  "theme_color": "#000000",
  "background_color": "#ffffff"
}
