Litestar
Modern, opinionated ASGI framework with first-class support for OpenAPI, dependency injection, DTOs, and WebSockets — a batteries-included FastAPI alternative
Visit Litestar →Litestar covers more out of the box than FastAPI does by default — built-in dependency injection scoping, DTOs (data transfer objects) for controlling exactly what gets serialized, and first-class OpenAPI generation, aimed at teams who want more structure without assembling it from separate packages.
Worth comparing directly against FastAPI or Robyn if raw framework speed and a more opinionated, batteries-included feature set both matter — see FastAPI vs Robyn vs Flask for how the ASGI framework landscape compares more broadly.
