modbender Supabase RLS Generator
Row Level Security is powerful but the policy syntax is tricky. This reads your schema and generates proper RLS policies.
One command. Zero config. Just works.
Quick Start
npx ai-supabase-gen ./prisma/schema.prisma
What It Does
- Reads your Prisma schema
- Generates Supabase RLS policies
- Handles common patterns (own data, team access)
- Includes policy enable statements
Usage Examples
# Generate from Prisma
npx ai-supabase-gen ./prisma/schema.prisma
Best Practices
- Enable RLS - it's off by default
- Test policies - verify they work as expected
- Use helper functions - auth.uid(), auth.role()
- Think about all operations - SELECT, INSERT, UPDATE, DELETE
When to Use This
- Setting up Supabase security
- Adding RLS to existing tables
- Learning RLS patterns
- Securing multi-tenant apps
