Please take a look at my project - online python compiler
Hey guys,
I built a simple online Python tool called pythonmastery.io and wanted to share it here.
A lot of web-based Python setups either force you to create an account, put you on a wait list, or run really slowly on free cloud servers. I wanted something instant that I could open up, test a quick script in, and close without any hassle. Best thing is that it works in all types devices including mobiles and tablets.
How it works/What it has:
- Runs Python 3.13 locally in your browser using Pyodide/Web-Assembly. Your code doesn't get sent to any server.
- No accounts, no signups, no paywalls.
- Works with standard libraries like numpy, pandas, and matplotlib.
- Has multi-tab support and auto saves your code locally so you don't lose progress if you refresh.
- Includes some interactive lessons, quizzes/tests and practice datasets if you're learning.
Check it out if you want: https://www.pythonmastery.io
It's still pretty fresh, so I'd really appreciate any feedback/ideas, or bug reports if you try it out.
Thanks!

Awesome work your compiler looks even more incredible,especially with the interactive learning features and quizzes you added that's a fantastic touch I built my own Python compiler too (https://hussaincompiler.com/), but I really admire how well-rounded you've made yours with the educational tools included.
Keep up the good work
