Push Agent lets visitors subscribe to browser notifications with one click, then reach them on Chrome, Edge, Firefox and Safari, even when your site is closed. Unlike most push tools it uses standard Web Push: no Firebase, unlimited notifications on every plan and simple monthly prices. Free WordPress and Joomla plugins, or one line of code for any site. Schedule, target by country or device, A/B test titles, auto-send new posts by RSS, and send WooCommerce order updates.
