## What it is
PWACompat is a small JavaScript library that brings Web App Manifest support to browsers that don't natively support it, such as Mobile Safari and older IE/Edge. It generates legacy icons, meta tags, splash screens, and theming from an existing manifest file.

## Use cases
- make my web app manifest work on iOS Safari
- generate splash screens for my PWA on iPhone
- support add-to-homescreen icons in older browsers
- backfill meta tags and icons from a manifest.webmanifest
- make my PWA look native on non-compliant browsers
- support IE/Edge pinned sites feature from a manifest

## When to choose
- you have a Web App Manifest but need wide browser support for icons, splash screens, and theming
- you want a drop-in script with no build step, loadable from a CDN
- you target iOS Safari users who add your site to the homescreen

## When to avoid
- your target browsers all natively support Web App Manifests
- you need full PWA features like service workers or offline support, which this does not provide
- you want an actively developed solution with new features
