Neon RLS is a new tool integrated into the Neon Data API, designed to simplify the implementation of row-level security (RLS) policies in PostgreSQL databases. It allows developers to manage RLS directly within their codebase and integrate with any authentication provider, thereby facilitating fine-grained access control with less complexity. By leveraging JSON Web Tokens (JWTs), Neon RLS enables authenticated database requests, which can be used in conjunction with RLS rules to enhance security. The tool supports integration with various authentication providers and offers a partnership with Drizzle ORM for a more intuitive setup of RLS policies. While it is recommended to use RLS for critical authorization logic, especially in multi-tenant enterprise applications, the decision to apply RLS universally remains a subject of debate. Neon RLS aims to make application development faster and more secure by allowing client-side applications without the need for a server or backend, although a backend is still advised for more substantial projects.
