Client libraries for every language

ExtraBase ships with intuitive client libraries. The same API you love, now available in JavaScript, TypeScript, Python, Swift, Dart, and more.

Auto-generated TypeScript types from your schema
Fully typed query builder with IDE autocomplete
Real-time subscriptions with a single line of code
Built-in auth helpers for SSR frameworks
Read the docs
import { createClient } from '@extrabase/js'
const client = createClient('YOUR_URL', 'YOUR_KEY')
// Query your database
const { data, error } = await client
.from('posts')
.select('*, author:users(name)')
.eq('published', true)
.limit(10)
// Subscribe to realtime changes
client.channel('posts')
.on('postgres_changes', { event: 'INSERT' }, cb)
.subscribe()
"

We built our entire realtime chat application on ExtraBase in less than a week. The automatic API generation and Row-Level Security saved us months of custom backend work.
