Seed Gen

Seed Generator

Testing with realistic data reveals bugs you'd never find with lorem ipsum. This tool reads your schema and generates proper seed data.

One command. Zero config. Just works.

Quick Start

npx ai-seed ./prisma/schema.prisma

What It Does

• Reads your database schema
• Generates realistic seed data
• Respects relationships and constraints
• Works with Prisma, SQL, Drizzle, and more

Usage Examples

# Generate from Prisma schema
npx ai-seed ./prisma/schema.prisma

# More records
npx ai-seed ./prisma/schema.prisma -n 50

# From SQL schema
npx ai-seed ./schema.sql -o seed.ts

Best Practices

• Make it repeatable - use a seed for random data
• Respect constraints - unique fields, foreign keys
• Test edge cases - empty strings, nulls, limits
• Keep it realistic - real names, real emails

When to Use This

• Setting up dev environments
• Testing with realistic data
• Demo environments
• Performance testing

How It Works

Parses your database schema, understands the types and relationships, and generates a seed script with realistic data. Uses faker-style data that looks real but isn't.
