About Pusher
Pusher is a hosted service for adding live, two-way features to web and mobile apps. Your backend sends messages to named channels, and connected clients receive them as they happen.
What it does
Pusher runs the messaging infrastructure behind realtime features, so your team does not have to build and maintain it. Your server publishes an event to a channel, and every client subscribed to that channel gets the event. Server libraries exist for several languages, and client libraries cover web, Android and iOS. Common uses include live dashboards, alerts, location updates and in-app chat.
Key features
- Publish events to named channels from your server
- Subscribe clients and bind handlers to events
- Client libraries for web, Android and iOS
- Push notifications through the Beams product
Who it's for
Teams that want to add live features to a web or mobile app without running their own realtime servers. It suits developers who prefer a hosted API over managing connections themselves.
Pricing and good to know
The homepage points to a free account to start. Paid plans and their limits are not described in the text reviewed here, so check the pricing page before you commit. Because Pusher is a hosted service, your messages pass through its servers.
