​
Run it

Edge Python ships as a WebAssembly module. The fastest way to try it is the playground — no install, runs entirely client-side via WebAssembly. Open the playground ->

​
Embed it

To run Edge Python in your own host (browser app, server, edge runtime), you need two artifacts:
  1. The compiler module: compiler_lib.wasm (~130 KB).
  2. A loader for your platform — the canonical browser loader is demo/edge.js; WASI hosts wire it up via their runtime’s import API.
Build the WASM yourself: 
git clone https://github.com/dylan-sutton-chavez/edge-python
cd edge-python/compiler
cargo wasm
# → target/wasm32-unknown-unknown/release/compiler_lib.wasm
There is no separate native CLI binary. The host runtime owns I/O, network, and module fetching — that’s what keeps Edge Python sandboxed by construction.

​
Your first program

Open the playground and paste: 
greet = lambda name: f"Hello, {name}!"

for who in ["world", "edge", "python"]:
    print(greet(who))
Output
Hello, world!
Hello, edge!
Hello, python!

​
A taste of the language

Edge Python is a functional subset of Python 3.13. Functions are first-class values. Lambdas, currying, higher-order functions, and comprehensions are central. 
# First-class functions
ops = [abs, len, str]
print([f(-3) for f in ops])

# Currying
add = lambda x: lambda y: x + y
print(add(3)(4))

# Pure functions get memoized automatically
def fib(n):
    if n < 2: return n
    return fib(n - 1) + fib(n - 2)

print(fib(20))
Output
[3, 2, '-3']
