Show HN: Online Python Compiler with Libraries

I don't understand. There is no compiling at all. It's interpereter and it's basically based on https://pyodide.org/
Maker here.
You're right, it's an interpreter and that would be the 100% accurate term.
For online coding environments, the two are often used interchangeably. More people search for 'compiler', so I'm using that widely on my site.

Who would search for "Python compiler"?
Honestly: It makes it sound like you literally have no idea what you're talking about. Not a good look for someone trying to sell a service.

Those who actually want to produce binaries from their Python scripts, which this doesn't do.

I personally saw how novice Python programmers searched for “Python compiler” while their actual intent was to find Python REPL/execution environment online (pythontutor, ideone, repl.it, trinket.io, etc)
Many of this services use “compiler” in their description. It may be technically true if they use Python implementation that compiles Python source to byte code first, and then interprets the resulting bytecode (like CPython, Pypy implementation do).

import requests
r = requests.get('https://theonion.com')
print(r.text)
Running arbitrary untrusted code seems like a potential security issue.
Edit: @porridgeraisin Got it, thanks! Does this mean outbound http requests only work with domains that support arbitrary requests via `Access-Control-Allow-Origin: *` ?
Maker here! Runs in an isolated Web Worker using Web Assembly, via Pyodide. Everything runs locally in your browser - no file system or other access. Scheduled run (paid plan) run on AWS lambda.
So, yes, sadly, network requests only work with domains with Access-Control-Allow-Origin: *. I'm looking at adding a backend CORS proxy to fix this.
We also have a Chrome extension with no CORS limitation. The extension lets you right-click Python code snippets on basically any site (Claude, ChatGPT, Deepseek etc.) to run it instantly.

You might check out https://e2b.dev, they already have a really robust sandbox system with nice SDKs.
Interesting, thanks
Yes, it has all the normal CORS restrictions. If you're curious, the PR that added support for this is here:
https://github.com/urllib3/urllib3/pull/3195
It runs on pyodide, i.e, a wasm interpreter that runs entirely in your browser.

Hi, great project! Can you add the library pylan? https://pypi.org/project/pylan-lib/
Yes! To use pylan:
- Click on the Clip name (the default one is 'Use Python Libraries') - Click 'Manage packages' - Enter 'pylan-lib' and Click 'Add' - Click 'Run'
The package will be installed, and the code will run!
The list of libraries is only a small subset of the compatible libraries - I should make that way clearer.

ah ok. Thanks!
Great project! Nice work!
It reminds me a bit of marimo: https://docs.marimo.io/guides/publishing/

Maker here. Thank you!
I looked briefly at Marimo when building - awesome project. I wasn't sure about building on Pydodide as it's obviously not full Python compatibility. But seeing someone else building a popular project on it helped me make that decision!

What am I paying for if it's running on my system ?
Not asking to deride , but could you elaborate what value this adds over simple installing python on my system ?
Looks awesome! big fans of pyodide, congrats on the launch
It uses Pyodide to execute Python in the browser using WebAssembly.
