v0 Database Setup Template

A complete authentication and database integration template for v0 projects with Supabase

Supercharge v0's AI with Database Context

The schema extraction tool generates JSON files that give v0 deep understanding of your database

Enhanced Understanding

• Application logic and data relationships
• Security policies and access control
• Data validation and constraints
• Query optimization opportunities

Better Code Generation

• Accurate SQL matching your schema
