Web App Manifest Generator (PWA)

Create a site.webmanifest for installable web apps (PWA) with name, colours, display mode and icons.

What is a web app manifest?

A web app manifest is a JSON file linked from your pages that tells browsers your app’s name, icons, colours and how it opens when installed to a home screen. Fill in the fields and copy the manifest plus the link and theme-color tags for your <head>.
