Everything You Need to Ship

A complete backend platform with all the tools developers love — open-source and self-hosted

PostgreSQL Database

Full Postgres power with auto-generated APIs. Row-level security, migrations, and real-time subscriptions built in.

Authentication

Email, OAuth, magic links, and phone auth out of the box. Built-in user management with role-based access control.

Real-time Subscriptions

Listen to database changes in real-time. Build collaborative apps, live dashboards, and chat with zero extra infrastructure.

File Storage

Upload, transform, and serve files with a simple API. Image optimization, access policies, and CDN delivery included.

Edge Functions

Deploy serverless functions that run close to your users. Write in TypeScript, deploy globally, scale automatically.

Row Level Security

Define granular access policies directly in PostgreSQL. Your data stays secure without writing middleware.

Tired of These Problems?

1

Vendor lock-in makes it impossible to switch providers

2

Cloud costs spiral out of control as you scale

3

No control over where your data lives or who can access it

4

Proprietary backends make debugging and customization painful

// With Postbase, you own everything
import { createClient } from 'postbase-js'
const postbase = createClient(
'your-server-url',
'your-anon-key'
)
const { data } = await postbase
.from('posts')
.select('*')
.order('created_at')
