I've built a free online editor that supports Python (plus SQLite, DuckDB, Lua, HTML/CSS/JS).
It runs entirely in the browser - no installation required. and No Signup
You can use it to:
- Prototype Python scripts instantly
- Test SQL queries (SQLite and DuckDB)
- Build small web apps with Python backend logic
- Practice coding without setting up a local environment
Check it out: https://pterocos.eu.org
I'd love feedback from the Python community. What features would make this more useful for you?
Thanks!
