Everything You Need for Notifications

From React components to REST APIs, CloudSignal handles the real-time infrastructure so you can focus on your product.

Drop-in Components

Pre-built React components for bell icon, toast popups, and notification feeds. Import, configure, ship.

Any Auth Provider

Works with Supabase, Clerk, Firebase, Auth0, or your own JWT auth. No vendor lock-in on identity.

Per-User Channels

Each user gets a private notification channel bound to their email. Broadcast announcements reach everyone.

REST API Publishing

Send notifications from any backend with a simple REST call. Node, Python, Go, cURL — whatever you use.
