OneSignal

We provide a simple, developer-friendly interface to push notifications for apps and websites.
We started as app developers who just wanted a developer-friendly API for push notifications. Finding no good solution, we built one ourselves.

Today, we are the leading solution for push notifications, supporting over 500,000 developers. OneSignal is available on every platform and development environment that supports push, letting content creators focus on quality user engagement instead of complex implementation.

Our goal is to democratize push communication for everyone from individual blogs to top tier apps.

We run the world’s fastest Rust backend, sending over notifications 700,000 / second - averaging 4 billion / day

We serve more than 100 million end users for each engineer on the team

We pride ourselves on prompt support and best in class documentation, to make sure every developer can run OneSignal

We support the latest notification features and offer first- or third-party SDKs for every major platform and device capable of push.
