NotifyBridge

A REST API platform and mobile app that lets hardware developers send push notifications to iOS and Android phones from devices like ESP32, Arduino, and Raspberry Pi. It solves the problem of complex mobile push setup by providing a simple HTTP POST webhook. It targets makers, hobbyists, and developers who build DIY hardware projects, as well as their friends, family, or operators who need to receive alerts. It is delivered as a cloud API with a companion mobile app, requiring no Firebase, APNs certificates, or mobile SDKs, and offers a free tier.
