Overview
Tagline Brand's website · 2026-10-04
PyPy is, on average, about 3 times faster than CPython 3.11 due to its Just-in-Time (JIT) compiler. It also offers lower memory usage for memory-hungry Python programs, high compatibility with CFFI, Cppyy, and popular libraries like Twisted and Django, and built-in stackless mode for massive concurrency.
