## What it is
A Prisma generator plugin that produces fully typed Kysely database types directly from your Prisma schema. It lets you keep Prisma's migration and schema workflow while writing type-safe SQL queries with Kysely instead of the Prisma Client.

## Use cases
- generate kysely types from prisma schema
- use prisma migrations with kysely queries
- write type-safe raw SQL with prisma schema
- replace prisma client with kysely
- generate database types for cloudflare d1
- get typescript types for sql queries from prisma

## When to choose
- you like Prisma's schema language and migration flow but find the Prisma Client too limiting
- you need multi-table joins or raw SQL performance without losing type safety
- you're targeting Cloudflare D1 or other databases where Kysely is preferred

## When to avoid
- you're happy with the Prisma Client's query API
- you don't use Prisma for schema management or migrations
- you need runtime query building rather than type generation
