Backends

Seven implementations, one contract

Each backend is written to feel native to its framework, and each passes the same sixteen contract tests. The frontend cannot tell them apart, and neither, from the outside, can you.

GoGo

The reference implementation. Standard library plus a thin router, hexagonal to the core.

FastAPIPython

Async Python, type-hinted end to end, with asyncpg talking to Postgres.

NestJSTypeScript

Opinionated modules and dependency injection, the Angular of the backend.

ExpressTypeScript

Minimal and unopinionated, so the hexagonal structure has to be deliberate.

LaravelPHP

Batteries-included PHP running on FrankenPHP, the service layer kept framework-free.

SymfonyPHP

Components and explicit wiring, the enterprise end of PHP.

PhalconPHP (C extension)

A framework compiled as a C extension, for when PHP needs to be fast.
