Web app manifest generator

Fill in name, short name, start URL, scope, display mode, colors, and icon paths to get a valid manifest.json plus the link rel=manifest snippet to paste.

Building the manifest…

The manifest lists icon addresses only; this tool never uploads or fetches an icon, so a broken address stays your problem to spot in deployment. Colors emit as hex, since that is what every engine accepts. Installability (a service worker, HTTPS, and the icon sizes Chrome wants) is not checked here; the sibling PWA manifest checker reads a deployed file instead.
