Build Your Backend Without Limits.
The open source alternative to Supabase and Clerk. PostgreSQL database, 25+ auth providers, file storage, and cron jobs — all self hosted and under your control.
Tell Us You Use a BaaS Without Telling Us
Checked your Supabase bill after a viral tweet?
That free tier didn't stand a chance.
Firebase said your data structure is 'not recommended.'
Cool, thanks for the vibes based database advice.
Waiting for a support ticket reply from a $50B company.
Meanwhile you're self hosting Postbase in 5 minutes.
Vendor migrates your region and 'forgets' to tell you.
Found out from the outage, obviously.
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
Everything You Need to Ship
A complete backend platform with all the tools developers love — open source and self hosted
Postgres Database
Every project is a full Postgres database, the world's most trusted relational database.
- 100% portable
- Built-in Auth with RLS
- Easy to extend
Authentication
Add user sign ups and logins, securing your data with Row Level Security.
25+ more integrations
Storage
Store, organize, and serve large files, from videos to images.
Cron Jobs
Schedule SQL snippets or HTTP requests, with full run history and no external infra.
Data APIs
Instant ready-to-use REST APIs.
Same Great Postgres Energy, Zero Vendor Lock In
We're not here to dunk on Supabase — it's a great product, and honestly the inspiration behind half of this feature list. But when the bill shows up after your launch day traffic spike, you deserve options.
- No surprise invoices when your side project gets a little traction
- Nobody's telling you which features are 'Pro only' this week
- Self host it, fork it, read every line — it's actually yours
Fetch Some Rows, Judge for Yourself
Real Relational Data, No Google Graveyard Risk
Firebase is fast to prototype with, until you need to query across collections and suddenly you're denormalizing everything by hand. Postbase gives you real PostgreSQL — and a company history longer than "we'll deprecate this in 2027."
- Actual SQL — JOINs, transactions, and relations that make sense
- No NoSQL data modeling gymnastics just to run a simple query
- Google can't sunset it — you're running the servers
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.
Built on tools you already trust
PostgreSQL
Next.js
Docker
Node.js
Railway
GitHubHow 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.

Your Data Doesn't Leave the Building
Row Level Security
Native Postgres RLS policies — access control lives in your database, not a bolted on rules engine.
You Hold the Keys
Service role and anon keys are yours. No third party sits between your app and your data.
Full Audit Trail
Every query runs against a database you control — logs, backups, and history are never a support ticket away.
No Data Sharing
Self hosted means your users' data never leaves infrastructure you chose.
Already on Supabase or Firebase? Bring Your Schema.
The SDK is intentionally familiar — if you know .from().select(), you already know Postbase. Export your Postgres data, point the SDK at your new instance, done.
Pricing? It's Whatever Your Server Costs.
No per seat fees, no row limits, no "contact sales" for basic features. Run it on a $5 VPS or a fleet of servers — the software is free either way.
What Developers Are Saying, Everywhere
Moved off Supabase after the third pricing tier surprise. Postbase's table editor feels almost identical, RLS just works.
self hosted this on a $6 droplet and it's handling our whole MVP without breaking a sweat
the AI SQL editor caught a missing index before I even ran the query lol
postgres + auto rest api + auth in one docker command. why did i wait this long to try this
Our agency switched three client projects over. Clients love that they own the data outright now.

Real JOINs, real transactions. Coming from Firestore this feels like using an actual database again.
cancelled my supabase pro plan today. postbase on railway costs me less than my coffee budget
cron jobs built in means I finally deleted that janky external scheduler service
storage buckets + RLS policies configured in an afternoon, docs were actually clear for once
migrated our internal tool's data with pg_dump in like ten minutes, no drama
Recommending this to every dev in our community group now, especially for client work.
