Sample web app manifest for testing — free, CC0

A web app manifest is the JSON a browser reads to learn a site's name, icons, colours and display mode — the file that decides what an installed web app looks like on a home screen.

webmanifest/site.webmanifest carries a name, short name, start URL, scope, display mode, theme and background colours, and two icons. The icons point at published PNG fixtures, so a tool that follows them gets real images back rather than a 404, which is the difference between testing a manifest parser and testing it properly.

It is served as application/manifest+json, a content type plenty of pipelines have never seen. That alone is worth checking: servers that guess types from extensions often return application/octet-stream for .webmanifest, and browsers then ignore the file entirely without an obvious error.

Use it to test manifest parsing, install prompts, icon resolution and content-type handling. Related formats: JSON and HTML.
