Live in production

What you get

Everything your product needs
to feel alive.

From a simple notification badge to a full collaborative experience — Zokai handles the real-time layer so you can focus on your product.

Instant delivery

Messages reach your users in under 5ms. No polling, no refreshing — just a seamless live experience that feels native.

Channels & rooms

Organize your events into public or private channels. Each channel is isolated per app — perfect for chat rooms, order feeds, or dashboards.

Presence

Know exactly who's online, right now. Show live cursors, active user lists, or "seen by" indicators without writing a line of backend logic.

Private channels

Restrict access to sensitive channels with server-side auth. Only users your backend approves can subscribe — zero configuration needed.

Scales automatically

Go from your first 100 users to millions without touching your code or your infrastructure. Zokai handles it all behind the scenes.

Simple REST API

Publish events from any backend with a single HTTP call. Official SDKs for Node.js, Python, Go, Ruby, and PHP — or use the API directly.

Built for every product

What will you build?

Zokai fits wherever your users need to see things happen in real time.

💬

In-app chat

Support, team, or customer messaging with typing indicators and read receipts.

📊

Live dashboards

Sales metrics, analytics, and KPIs that update the moment data changes.

🛒

Order tracking

Push order status updates the instant they happen — no refresh required.

🤝

Collaboration

Live cursors, shared editing, and real-time co-presence in your product.

How it works

Up and running in minutes.

Three simple steps from sign-up to live events in your app.

Create your app

Register and create an app in the dashboard. You'll get an API key and secret — that's all you need to start sending events.

Add the client SDK

Install the SDK, connect with your key, and subscribe to a channel. One line of code per event type — no boilerplate, no config files.

Publish from your backend

Call the REST API or use an SDK from your server. Events arrive at every connected client in milliseconds — automatically, at any scale.
