Overview
Kysely brings type-safe SQL queries and schema migrations to TypeScript projects with adapters for PostgreSQL, MySQL, SQLite, and more.
Pros
- Strong TypeScript type safety for queries and schemas
- First-class schema migrations support
- Works with multiple SQL dialects via adapters
- Lightweight and close to raw SQL
- Good developer experience for typed database code
Cons
- Smaller ecosystem than major ORMs
- Requires writing SQL queries manually
- No full ORM features like model relations by default
- Some advanced workflows need extra setup or plugins
Verdict
Kysely is excellent for TypeScript teams that want type-safe SQL without a heavy ORM abstraction. It is best for projects where developers prefer explicit queries and predictable migrations. The main trade-off is less built-in ORM convenience compared to tools like Prisma or TypeORM.
