Insant

Instant is a modern Firebase. We make you productive by giving your frontend a real-time database.

You write relational queries in the shape of the data you want and Instant handles all the data fetching, permission checking, and offline caching. When you change data, optimistic updates and rollbacks are handled for you as well. Plus, every query is multiplayer by default.

We also support ephemeral updates, like cursors, or who’s online. Currently we have SDKs for Javascript, React, and React Native.

How does it look? Here’s a barebones chat app in about 12 lines:

// ༼ つ ◕_◕ ༽つ Real-time Chat
// ----------------------------------
// * Updates instantly
// * Multiplayer
// * Works offline

import { init, tx, id } from "@instantdb/react";

const db = init({ 
  appId: process.env.NEXT_PUBLIC_APP_ID,
});

function Chat() {
  // 1. Read
  const { isLoading, error, data } = db.useQuery({
    messages: {},
  });

  // 2. Write
  const addMessage = (message) => {
    db.transact(tx.messages[id()].update(message));
  };

  // 3. Render!
  return <UI data={data} onAdd={addMessage} />;
}
