What each one is

The product in its own terms, so the numbers below have context.

Kysely

Leader

A JavaScript and TypeScript SQL query builder that provides compile-time type safety and database schema validation. It works across multiple runtimes (Node, Deno, Bun, Cloudflare Workers, browsers) with zero runtime dependencies and emphasizes composable, type-safe queries over higher-level abstractions.
