| deployment.options | `{"self_hosted":true}` | - |
| description.long | A Rust library that provides type-safe database access with compile-time verification, featuring both a query builder API and raw SQL support across multiple database systems including PostgreSQL, MySQL, and SQLite. | An open-source ORM for Node.js that emphasizes working with SQL queries rather than abstract objects, built on the Knex query builder. It supports TypeScript and multiple database backends while maintaining access to raw SQL when needed. |
