TypeScript ORM that feels like writing SQL.

Drizzle ORM is a TypeScript ORM for SQL databases designed with maximum type safety in mind. It comes with a drizzle-kit CLI companion for automatic SQL migrations generation. Drizzle ORM is meant to be a library, not a framework. It stays as an opt-in solution all the time at any levels. The ORM's main philosophy is "If you know SQL, you know Drizzle ORM". We follow the SQL-like syntax whenever possible, are strongly typed ground up, and fail at compile time, not in runtime.

Neurosync is a javascript ORM that is offline & real-time capable.

ORM you say? Neurosync doesn't do anything crazy directly with a database - the database to Neurosync is a facade typically backed by a REST API. It's an ORM in the sense that it handles creating, updating, and deleting relational data to any degree you wish.
