What subscribers receive
Realtime primitives
The core building blocks behind every live product experience.
Foony Realtime gives product teams a managed realtime layer: channels for fanout, presence for liveness, history for recovery, and scoped auth for safe clients.
presence.enter()
Presence
Track who is online, refresh membership automatically, and react to enter, update, and leave events.
channel.history()
History
Replay recent messages from durable storage so clients can recover cleanly after reconnects.
POST /auth/token
Scoped auth
Mint short-lived client tokens from your backend with channel-level publish, subscribe, presence, and history permissions.
No 50-a-second channels. No 10 KB message caps.
Typical realtime platforms cap each channel at around 50 messages a second, reject payloads over a few kilobytes, and bill messages, connections, channels, and bandwidth separately. Foony Realtime meters one thing: messages.
Uncapped
Per-channel throughput
Channels have no rate ceiling of their own. Push one channel as hard as your plan allows.
1 MB
Max message size
On Growth and up. Free starts at 64 KB, the paid ceiling on most platforms.
150,000/s
Messages per second
Per-app throughput on Scale. Enterprise runs uncapped.
AES-256
End-to-end encryption
Encrypt in the SDK with a key only you hold. The service only ever sees ciphertext.
30 days
Message history
Replay any channel, so reconnecting clients recover cleanly instead of starting blind.
$0.25
Per million extra messages
Flat plans from $0. Connections and channels never bill separately.
Start with a channel. Scale into a platform.
Create an app, install the SDK, publish an event, and watch it arrive in the channel inspector.
const realtime = new Realtime({ authCallback });const channel = realtime.channels.get('chat:lobby'); channel.on((message) => { showMessage(message.data);}); await channel.publish('chat', { text: 'hello' });await channel.presence.enter({ name: 'acorn' });Create an app
Get an app ID, environment, and server key from the dashboard.
Install the SDK
Use TypeScript-first clients for browser and server workflows.
Subscribe to a channel
Listen for messages, presence changes, and history from one app-scoped namespace.
Watch it live
Inspect channel traffic, delivery health, and usage before launch.
