Edge Python's a Rust-written compiler/VM for Python 3.13 bytecode, squeezing into <200KB with full features like GC and dicts — for embedded/WASM.

Can Edge Python run CPython code?

Mostly — benchmarks show it, but edge cases lurk; test your scripts on the GitHub repo.

Is Edge Python faster than MicroPython?

On fib(45), obliterates it; loops match CPython. GC adds pauses, but size crushes competitors.

Why build Edge Python in Rust?

Rust's zero-cost abstractions + safety let it beat C hacks while staying tiny and crash-proof.

Imagine squeezing a full Python interpreter into 200KB for your IoT gadget — that's Edge Python now, with garbage collection that actually works. But does this kill MicroPython, or just tease us?
