## What it is
A JavaScript library that polyfills the HTML5 Notification API to provide desktop notifications across Chrome, Firefox, Edge, Safari, and IE9+. It replaces the native Notification constructor with a custom one that normalizes behavior and adds a 'notsupported' permission level for unsupported environments.

## Use cases
- show desktop notifications in the browser
- polyfill Notification API for IE9
- cross-browser web notifications
- request notification permission with a unified API
- display notifications with custom icons in older browsers

## When to choose
- you need desktop notifications in legacy browsers like IE9 or old Edge
- you want a single Notification API that works across Chrome, Firefox, Safari, and IE
- you need graceful handling of environments without Notification API support

## When to avoid
- you only target modern browsers with native Notification API support
- you need service-worker-based push notifications
- the project appears largely unmaintained with an unclear license
