## What it is
A CLI tool that generates Kysely TypeScript type definitions by introspecting your database schema. It supports PostgreSQL, MySQL, SQLite, MSSQL, and LibSQL, outputting a .d.ts file for type-safe query building.

## Use cases
- generate kysely types from database schema
- create typescript type definitions for sql database
- type-safe database queries with kysely
- introspect postgres schema into typescript types
- generate db types for mysql or sqlite
- keep database types in sync with schema

## When to choose
- you use Kysely and want type-safe queries without hand-writing interfaces
- your database schema changes often and you want to regenerate types
- you want a simple, focused codegen tool with multi-database support

## When to avoid
- you use an ORM other than Kysely (e.g. Prisma, Drizzle have their own codegen)
- you need runtime schema validation rather than compile-time types
- you don't use TypeScript

## Facets
- artifact type: cli-tool
- maturity: active
- function: cli, database, orm, type-system, developer-tools
- domain: databases, developer-tools, backend, web-development
- platform: cli, cross-platform
