Bilt integrates with Supabase to give your app a full backend — user authentication, a PostgreSQL database, and real-time data — without writing backend code.

​
Connecting Supabase

1

Open your project

Go to your project’s chat interface
2

Connect Supabase

Click the Supabase connection option or ask the AI: “Connect to Supabase”
3

Authenticate

Sign in with your Supabase account via OAuth. Bilt uses PKCE flow for secure authentication.
4

Select organization and project

Choose which Supabase organization and project to connect.

​
What you get

Once connected, your Bilt app can:
  • User authentication — Sign up, log in, password reset, and session management via Supabase Auth
  • Database — Read and write data to PostgreSQL tables
  • Real-time subscriptions — Live updates when data changes
  • Row-level security — Supabase’s built-in security policies protect your data

​
How it works with the AI

After connecting Supabase, you can ask the AI to build features that use it: 
Add user registration and login screens using Supabase auth

Create a table for user posts and display them in a feed

Show real-time notifications when a new message arrives
The AI generates the code that connects to your Supabase project — API calls, auth flows, and data queries.

​
Database inspector

Bilt includes a database inspector that lets you:
  • Browse your Supabase tables and their data
  • See column types and relationships
  • View auth users
  • Run SQL queries directly
This helps you understand what the AI built and verify that data is being stored correctly.

​
Connection types

TypeDescription
