This plugin uses the <a href="https://www.w3.org/TR/push-api/" rel="nofollow ugc">W3C Push API</a> to allow you to send push notifications to anyone who visits your site and signs up for notifications.
Once you’ve installed and configured this plugin, anyone visiting your site/app in <a href="http://caniuse.com/#feat=push-api" rel="nofollow ugc">browsers that support the W3C Push API</a> (Firefox and Chrome, at the time of writing) will be asked whether they want to receive notifications from your site. You will immediately be able to send push notifications to anyone who consents.
Configure the plugin in the Settings > Web Push section of your WordPress installation. Here you can set various pieces of configuration, including:
<ul>
<li>The title for push notifications that appear from your site</li>
<li>When to attempt to register your visitor for push notifications (e.g. after how many visits)</li>
<li>Which types of events should trigger push notifications (e.g. new posts, comments, updates to posts)</li>
</ul>
N.B.: This plugin requires your website to be served via HTTPS. Indeed, for security reasons, browsers enforce the HTTPS policy for the Push API and for Service Workers.

This plugin offers the following features:
<ul>
<li>Collect subscribers that want to receive your notifications</li>
<li>Send push notifications directly from WordPress when you publish something new</li>
</ul>

<li>bell: a floating action button that allows users to subscribe to notifications</li>
