BlackSheep VS orjson

Try BlackSheep | Kore | socketify | baize

As you can see, in this benchmark Starlite handily beats even blakchseep, a notoriously fast ASGI framework written in Cython

If you have something that really needs to go fast, I recommend blacksheep. FastAPI is slow as molasses compared to blacksheep, and as of to date, the fastest python async web framework with the established feature set. It’s written in cython, so that might something to consider if you want to work with the source code somehow.

Personally I haven’t used it outside of trying a few very basic things. I’d recommend blacksheep if you want small, performant and low overhead, or sanic which, in my opinion, is the best choice if you do not need all the Django fluff.

orjson is the fastest JSON library available for python. It natively manages dataclass objects, datetime, numpy and UUID objects.

As we began venturing down that road, a few things emerged that would constitute significant changes to some of the core parts of Litestar, but there were two things in particular that started a chain reaction of changes by opening up further possibilities: The new DTOs and our switch from orjson to msgspec.

In version 1.45.0, we introduced msgspec as our serialization backend, replacing orjson. This had some immediate performance benefits, but that's not the main reason we made the switch.

Doesn't orjson do that already?

orjson

For most cases, you would want to go with python’s standard json library which removes dependencies on other libraries. On other hand you could try out ujsonwhich is simple replacement for python’s json library. If you want more speed and also want dataclass, datetime, numpy, and UUID instances and you are ready to deal with more complex code, then you can try your hands on orjson
