About OneSignal and how to get started

What is OneSignal?

OneSignal is a high volume and reliable push notification service for websites and mobile applications. We support all major native and mobile platforms by providing dedicated SDKs for each platform, a RESTful server API, and an online dashboard for marketers to design and send push notifications.

What are Push Notifications?

Push notifications are a feature built into mobile devices, web browsers, and operating systems. They are an easy way for developers and marketers to send short, real-time, messages to users with announcements, news, or events.

Why should I use OneSignal?

Easy to use - Implementing reliable interfaces to the GCM/FCM (Google) and APNS (Apple) 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. These protocols also change frequently, for instance, Apple recently released a new notification protocol and deprecated their old one.

Advanced Functionality - OneSignal provides marketing tools including A/B testing, segment targeting, 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, Safari, Chrome Web, and Firefox.

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

Free - Best of all, OneSignal is a free service that supports unlimited devices and notifications.
