Web Manifest Builder
Generate a Web App Manifest (manifest.webmanifest) for PWAs.
About this tool
Generate a Web App Manifest (manifest.webmanifest) for PWAs. Scaffold placeholder content, cron schedules, test data, and project boilerplate without extra CLI installs.
Fill name, short name, start URL, and display mode for your PWA. Set theme/background colors and icon paths (192 and 512). Example — Minimal installable app manifest: try `name: Demo App, start_url: /, display: standalone, icons: 192 + 512` and expect something like `{ "name": "Demo App", "short_name": "Demo", "start_url": "/", "display": "standalone", "icons": [/* ... */] }`.
Does not generate icon image files — point src at real PNGs you host. See also: Favicon Generator, and Meta Tags Generator. Runs in your browser — nothing you paste gets uploaded.
How to use
- Fill name, short name, start URL, and display mode for your PWA.
- Set theme/background colors and icon paths (192 and 512).
- Generate the JSON and save as manifest.webmanifest (or manifest.json).
- Link it from HTML with <link rel="manifest" href="/manifest.webmanifest">.
