Our scan also samples projects by dependency (Solana 2,661, Ethereum and EVM 1,496, 3D and games 2,818, agent frameworks and SDKs 10,983); counting those, it appears in 20 projects, and what it is used with below comes from all of them. The most used alternative in our scan is Drizzle ORM (251 projects). Projects that use it most often also use Express (70.0%), dotenv (70.0%), nodemon (65.0%).
