Manifest Generator

A web app manifest is the JSON file that tells browsers how your progressive web app should behave when installed — its name, icons, colours and display mode. This free manifest generator builds a valid manifest.json from a simple form, so you do not have to memorise the spec. Everything runs in your browser.

FAQs


What is a web app manifest?
It is a JSON file that describes a progressive web app to the browser — its name, start URL, display mode and colours — enabling installation on devices.


How do I use the generated file?
Save it as manifest.json and reference it from your pages with a link tag pointing to the file.


Do I need icons too?
Browsers expect icon files for installation. Generate those separately and add an icons array to the manifest.
