# Docker

  logtoio/logto:latest

# Cloud: cloud.logto.io (free, 50K MAU)
Enter fullscreen mode Exit fullscreen mode 
// React SDK
import { LogtoProvider, useLogto } from '@logto/react';

function App() {
  return (
    <LogtoProvider config={{ endpoint: 'https://your.logto.app', appId: 'your-app-id' }}>
      <MyApp />
    </LogtoProvider>
  );
}

function LoginButton() {
  const { signIn, isAuthenticated } = useLogto();
  if (isAuthenticated) return <p>Logged in!</p>;
  return <button onClick={() => signIn('http://localhost:3000/callback')}>Sign In</button>;
}

Why Developers Choose It

Auth0 charges $23/mo at 1,000 MAU. Clerk costs $25/mo:

  • 50K MAU free — most apps never need a paid plan
  • Beautiful by default — login pages look professional out of the box
  • Organizations — multi-tenant SaaS auth built in
  • Self-hosted — zero auth costs forever

A SaaS startup was paying $230/mo for Auth0 at 10K MAU. They migrated to Logto Cloud — 50K MAU free, same social login providers, and the login page looked better without any custom CSS.
