Built for AI

Get a backend designed to be operated from the CLI. Your agent can do everything a human can do with a dashboard, and when things go wrong, undo is built in.

Never leave your terminal

Create an account, spin up a database, push schema, and build from the terminal. No dashboards. No clicking through UIs. Just you, your agent, and your code.

$npx instant-cli push schema

Data Model Example

// Declarative data model
// ----------------------------------
import { i } from "@instantdb/core"
const schema = i.schema({
  entities: {
    messages: i.entity({
      text: i.string(),
      createdAt: i.date(),
    }),
  },
})

export default schema

Easy for humans, perfect for LLMs

Instant has a tiny API surface. Modern LLMs already know it from their training data. And it takes only 1% of context for advanced features.

End-to-end type safety

Instant comes with types for your schema, permissions, queries, and transactions. This makes it easy to catch errors early. Your AI can understand your data model and generate correct code on the first try.

Undo destructive changes

LLMs can make mistakes. For destructive actions like schema deletions, Instant comes with built-in undo. Restore deleted columns instantly.

Startups love Instant

Some of the best developers have bet their infrastructure on Instant. They do it because it helps them move fast and focus on wowing their users.

Batteries included

As your app grows, you start needing more services. Instant comes with a bunch of the fundamental ones built-in, and they're designed to work well together.

Auth

Magic Code emails, Sign in with Google, Apple, GitHub, and LinkedIn are all built-in with your app. Agents can set these methods up in minutes and they're extendable too.

Payments

Build apps that monetize. Easily add one-time purchases, subscriptions, or usage-based billing by telling AI to add Stripe to your Instant app.

Presence

Make your apps feel alive. You can use Presence and Broadcast services to share who's online, who's typing, or whose cursor is moving.

Instant updates

Click a button, toggle a switch, type in a field — whatever you do, you see the result right away. Your apps feel fast, so your users stay in flow.

Real-time sync

Multiplayer experiences work out of the box. If one person makes a change, everyone else can see it right away. No need to refresh or re-open the app to see the latest.

Works offline

Instant apps keep working when you lose connection. When your users get back online, everything syncs up without them having to do a thing. Pure magic.

Relational at the Core

Real apps aren't flat. Data needs to connect. Most backends make you choose between real-time sync and relational queries. Instant gives you both.

Ship something delightful.

You can start building out your dreams today. We never limit or freeze your projects.
