URI-based connections (e.g., postgresql:// or mariadb://) allow switching between supported databases without code changes, as outlined in the README's driver table.

Handles query parameter templating with declared OCaml types, ensuring compile-time type safety and reducing runtime errors, as demonstrated in the tutorial examples.

Integrates with multiple async runtimes like Lwt, Async, Eio, and Miou, providing adaptability for different OCaml application architectures.

Offers an experimental pgx driver for unikernel environments, enabling database access in MirageOS projects, though it's not recommended for production.
