Why should I use OneSignal?

Easy to use - Implementing reliable interfaces to the GCM/FCM (Google), APNS (Apple), and the Web Push protocols is difficult. There are open source projects to do it, but even the best ones break when message quantity begins to exceed 500,000 at a time.

Better Than The Competition - Other notification services lack features such as segmentation , automatic/triggered notifications, tag-variable substitution, a notification delivery Server REST API, or detailed reporting tools. Additionally, other services often provide low quality or out of date SDKs that do not support new platform features.

Advanced Functionality - OneSignal provides marketing tools including A/B notification testing, segment targeting, variable-substitution, localization, drip marketing, and conversion tracking.

Platform Support - OneSignal provides a single UI and API to deliver messages across iOS, Android, Amazon Fire, Windows Phone, Chrome Apps, Amazon Alexa, Safari, Chrome Web, and Firefox.

SDK Support - OneSignal provides SDKs for nearly every major cross-platform mobile development environment, including Unity, PhoneGap, Cordova, Ionic, React Native, Intel XDK, Corona, Xamarin, Marmalade, Adobe Air, and Web Push.

Popular - OneSignal is the most widely used push notification service for both web and mobile developers, with over 850,000 registered developers and 300,000 applications and websites.

An amazing value - Best of all, OneSignal provides a generous free service along with a paid service that can scale to unlimited devices and notifications. Some restrictions on the free plan. More on Paid Plan Benefits
