What each one is

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

Dapper

A micro-ORM for .NET that extends ADO.NET connections to execute SQL queries and stored procedures, supporting both synchronous and asynchronous operations with features for object mapping, dynamic SQL building, and multi-result set processing.

Independently observed

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.
