Web App Manifest Generator

Fill in the install name, launch path, display mode, colours, categories, and icons; get a ready-to-serve manifest.webmanifest with installability checks beside it. Copy or download the JSON, or use the generated data URI for a quick prototype. Everything runs locally.

     What makes a manifest installable? 
    
Browsers usually expect a name or short name, a same-origin start URL,
        a display mode such as standalone, and suitable icons. A
192x192 icon covers common launcher surfaces; a
512x512 icon supports richer install UI. Add a
maskable icon so Android launchers can crop it safely.
        Your site must also be served over HTTPS and link this file with
<link rel="manifest" href="/manifest.webmanifest">.
