Real-time features require WebSocket infrastructure that most servers don't handle well.
Pusher Channels provides managed WebSocket infrastructure for real-time features: live notifications, collaborative cursors, presence indicators, and event-driven UI updates. We implement Pusher for production applications that need real-time without the infrastructure overhead.
Application that needs real-time features — notifications, live updates, collaboration — but doesn't want to manage WebSocket server infrastructure
Real-time features — notifications that appear without page refresh, live activity feeds, collaborative editing indicators — require a persistent connection between the server and the browser. HTTP request/response is one-directional; the server can't push data to the client without the client polling.
WebSockets solve this: a persistent bidirectional connection where the server can push events to the client. The problem is that WebSocket connections are stateful and persistent — which is the opposite of what serverless infrastructure is designed for.
Serverless functions (Vercel, AWS Lambda) can't maintain WebSocket connections. Each function invocation is stateless; the connection dies when the function returns. This is fundamental to serverless architecture.
Pusher solves this by being the WebSocket layer. The backend (Next.js) triggers events via the Pusher HTTP API. Pusher maintains the WebSocket connections and delivers events to subscribed clients. The Next.js server never manages WebSocket connections.
The architectural pattern:
- Backend event occurs (new message, status change, notification)
- Next.js Route Handler calls
pusher.trigger('channel', 'event', data) - Pusher delivers the event to all clients subscribed to that channel
- React component updates in real-time via Pusher's JavaScript client
Pusher real-time integration with event publishing, channel subscriptions, and the React patterns that update UI in real-time when backend events occur
Channel design
Public channels (broadcast to all subscribers), private channels (user-authenticated), presence channels (who's online). Channel naming and access control design.
Backend event triggering
`pusher-http-node` integration in Route Handlers, Server Actions, or background jobs. Event publishing when relevant database writes occur.
Frontend subscriptions
`pusher-js` React integration with custom hooks. Channel subscription and event binding. UI update on received events.
Presence indicators
Presence channels for "who's online" features. Collaborative document editing cursor indicators. User activity tracking.
Authentication
Pusher channel authentication for private and presence channels. Auth endpoint that validates user access before allowing channel subscription.
One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Real-time feature scope is defined by the event types and channel architecture. Fixed price.
Questions, answered.
Pusher Channels: simple, well-supported, good DX, limited to events (not a full pub/sub). Ably: more powerful protocol, better for complex real-time applications. Supabase Realtime: if already using Supabase, real-time on database changes is built in. For simple notification and live update use cases, Pusher is the fastest to implement.
Pusher's free tier includes 200 max connections and 200,000 messages/day. The Starter plan ($49/month) supports 500 max connections. This covers most small-to-medium applications; large concurrent user applications need higher plans.
