GesherPush notifications for web apps

A managed VAPID web push service — subscribe, deliver, and measure without running your own push infrastructure.

VAPID web push

End-to-end encrypted web push using standard browser APIs and a shared VAPID key you can fetch or pass in from your app.

Multi-app isolation

Each app has its own API key and subscriber namespace. Subscriptions are keyed by app, user, and endpoint.

Rate limiting

Notify endpoints are rate-limited per app plan so bursts don’t overwhelm your quota or the service.

Usage metrics

Stats endpoints expose subscriber counts, 24h delivery summaries, and paginated subscription and delivery logs.

What is Gesher?

Gesher (גשר) is a managed push notification service for web applications. Your backend calls a simple HTTP API to send notifications; browsers receive them through a service worker using Web Push and VAPID.

You keep API keys on the server only. The browser talks to your subscribe/unsubscribe proxy; that proxy forwards to Gesher with the app’s Bearer token.
