to a working chat
From npm install to live chat
Use your existing user database. Sign a JWT on your backend, pass it to the SDK, and chat works. No user migration, no separate auth system.
Install the SDK
npm install @opiniom/react
Sign a JWT
HS256-sign your user's ID on your backend, pass it to the SDK
Render or go headless
Use <ChatWidget /> for instant UI, or hooks for a fully custom design
import { OpinioMProvider, ChatWidget } from '@opiniom/react';
function App() {
return (
<OpinioMProvider
projectKey="ok_live_your_key"
jwt={userJwt}
>
<YourApp />
<ChatWidget /> {/* That's it. Chat is live. */}
</OpinioMProvider>
);
}What you don't have to build
Every feature below is handled by OpinioM's backend. You write zero infrastructure code.
Real-time delivery
Messages arrive over a persistent WebSocket. Optimistic UI updates show messages instantly before server confirmation.
Headless or drop-in
Use the pre-built widget for quick setup, or go fully headless with React hooks to build any UI you need.
Framework-agnostic
React hooks, Lit web components, or vanilla JS. Works with Next.js, Vue, Svelte, and any stack that runs JavaScript.
Your auth, your users
No separate user database. Sign a JWT with your existing users and OpinioM handles the rest. Zero migration needed.
Webhooks + events
React to chat events in your backend. HMAC-signed webhook delivery with automatic retries and a delivery log.
Analytics built in
Message volume, active users, and conversation metrics — aggregated daily with CSV export.
Build any chat experience
Your customers' apps are unique — their chat should be too. OpinioM gives you the real-time engine; you decide what it looks and feels like.
Customer support
Embed a support widget in your app. Customers message your team directly — no Zendesk or Intercom needed.
Marketplace messaging
Buyers and sellers chat about orders. You control who can talk to whom — OpinioM handles real-time delivery.
In-app collaboration
Team chat, project discussions, or collaborative workspaces. Groups, channels, and DMs out of the box.
Built for production
Security, reliability, and compliance from day one.
AES-256 encryption
Secrets encrypted at rest, JWTs signed with HS256
Auto-reconnect
Redis-backed WebSocket with exponential backoff
GDPR ready
Data erasure endpoint, no third-party data sharing
Multi-node scaling
Socket.io Redis adapter for horizontal scale
Designed for developer experience
TypeScript-first. Every hook, every event, every response is fully typed. No runtime surprises, no "any" types, no guessing at payload shapes.
// Every hook returns typed data + loading/error state
const { messages, loadMore, hasMore } = useMessages(convId);
const { send, isLoading, error } = useSendMessage(convId);
const { onKeystroke, stopTyping } = useSetTyping(convId);
const typingUserIds = useTyping(convId); // string[]
const presence = usePresence(userId); // "online" | "away" | "offline"
const unread = useUnreadCount(); // number
const reactions = useReactions(messageId); // { "👍": ["user_1"] }
// Actions return loading + error — no manual state management
const { upload, isLoading } = useUploadFile();
const { create } = useCreateConversation();
const { edit } = useEditMessage(convId);
const { remove } = useDeleteMessage(convId);
const { addReaction } = useAddReaction();Free to start. Transparent to scale.
Start with 1,000 monthly active users — no credit card, no time limit. Upgrade when you're ready.
