Show HN: BustAPI – A Python framework with a Rust core claiming 50x Flask speed

[ZOROX]

Hi HN,

We’ve all accepted the "Python tax"—you trade execution speed for developer happiness. But what if that trade-off was a thing of the past?

I just came across BustAPI, and it’s basically a "cheat code" for Python web services. It’s not just another wrapper; it’s a hybrid engine that embeds a Rust (Actix-Web) core directly into the Python runtime.

Is this the end of the "slow Python" era? The benchmarks are pretty shocking. I’d love to see someone stress-test this against a production-grade Go or Node.js setup.

A new user "just came across" a clearly AI-written project and felt the need to post a clearly AI-written Show HN post about it? I'm rather skeptical.

Why not benchmark Flask/FastAPI with 8 workers instead of 4 for a more apples-to-apples comparison?

all framework except Catzilla run with 8 workers for benchmark

you should run yourself for testing.
