Unlike Flask or FastAPI, this framework builds its core HTTP server in Rust, but lets you write your API code comfortably in Python. It runs as a single process with multiple workers, taking full advantage of Python's no-GIL mode. In microbenchmark tests with the WRK tool, it crushes 120,000 requests per second (RPS) without GIL, double the 50-60k RPS with GIL and still outperforms both Flask and FastAPI.
