A Rust-written compiler/VM for Python 3.13 bytecode, total size under 200kb, with SSA optimizations and now a mark-sweep GC .

Does Edge Python run full Python scripts?

Mostly – core ops yes, but some advanced features error out with VmErr. Getting there fast.

Is Edge Python faster than CPython?

Blazing on recursive fib due to memoization; loops on par. Real-world

Can I use Edge Python for embedded devices?

Absolutely the goal – tiny footprint screams IoT, MicroPython rival without subsets.

Edge Python's 200KB Beast Awakens with Real Garbage Collection

fib(45) done in 11 milliseconds. That's Edge Python – a 200KB Python 3.13 compiler written in Rust, now with proper garbage collection. CPython's still gasping at two minutes.

Edge Python benchmark table: fib(45) 0.011s vs CPython 1m56s

⚡ Key Takeaways

Edge Python adds mark-sweep GC, VmErr, and fixes in under 200KB – embeddable Python dream. 𝕏
fib(45) benchmark warps via memoization, but loops prove parity with CPython. 𝕏
Bold bet: Could power IoT/WASM Python, echoing Lua's lightweight legacy. 𝕏
