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 an auto-generated API. Query via anon key (RLS-enforced) or service_role key, run JOINs and raw SQL from the SDK.
Authentication
25+ providers — email/password, OAuth, magic links, passkeys, and phone auth — toggle any of them from the dashboard.
AI-Powered SQL Editor
Write and run SQL directly from the dashboard, with AI-assisted query generation and human-readable result summaries.
File Storage
S3-compatible object storage with bucket policies. Connect Amazon S3, Cloudflare R2, Backblaze B2, and more.
Cron Jobs
Schedule SQL snippets or HTTP requests on any schedule, with full run history and no external infrastructure needed.
Row Level Security
Define granular access policies directly in PostgreSQL. Your data stays secure without writing middleware.
See It in Action
Everything you need ships with the dashboard — no third-party tools required.
Beautiful Landing Page
Postbase ships with a polished, dark-themed landing page — ready to showcase your product from day one.

Tired of These Problems?
Vendor lock-in makes it impossible to switch providers
Cloud costs spiral out of control as you scale
No control over where your data lives or who can access it
Proprietary backends make debugging and customization painful
How It Works
From zero to production in minutes, not months
Install Postbase
One command to get your entire backend up and running. Docker, bare metal, or cloud — your choice.
Build Your Schema
Design your database with the table explorer or write raw SQL. Query it through an auto-generated REST API from the postbasejs SDK.
Ship to Production
Connect your frontend with the postbasejs client library. Authentication and storage are already configured.
