How to Use Supabase with Vibe Coding Tools
Use this when you are adding real data, auth, and storage, not just dropping in a database logo and hoping the defaults are sane.
Hard part most people skip
The hard part is not connecting Supabase. It is designing the schema, RLS, and auth behavior so the app is safe and understandable under real usage.

Use AI for
- +Scaffolding tables and CRUD flows
- +Generating auth flows and storage integration
- +Writing baseline SQL and helper functions faster
Do not trust AI with
- −Creating policies that are too broad or too magical to reason about
- −Spreading privileged logic into the frontend
- −Generating schema decisions without a clear model of the product
Do this manually
- •Decide who should read and write what before generating policies
- •Review every RLS policy yourself
- •Model the lifecycle of the core objects in the app before adding more tables
Workflow that actually works
Step 1
Sketch the core objects and who owns them.
Step 2
Add auth and the minimum schema first.
Step 3
Write and review RLS policies before generating more product features.
Step 4
Test with a second user account so you catch leaks and permission mistakes early.
Create a Supabase project
Sign up at supabase.com and create a new project. Note your project URL and anon key.
Design your schema
Use the Supabase dashboard or prompt your AI tool to generate SQL for creating tables.
Set up Row Level Security
Enable RLS on all tables and create policies to control who can read and write data.
Connect your app
Install the Supabase client library and initialize it with your project credentials.
Add authentication
Use Supabase Auth for email/password, magic links, or social logins.
Enable realtime if needed
Turn on realtime for specific tables to get live updates via WebSocket subscriptions.
