Pterocos - Online Code Editor (With AI)

Question

I built a free, browser-based editor that supports multiple languages - including Python, SQL, and Lua - without any local setup. (no signup) (no install) to use!

Why I built it
I wanted a single place to quickly prototype:

• Python scripts without activating a virtual environment
• SQL queries (SQLite and DuckDB) for data analysis
• Lua snippets for game or config logic
• HTML/CSS/JS alongside backend code

What Pterocos includes

• Python – run scripts instantly
• SQL – SQLite and DuckDB support
• Lua – lightweight scripting
• Web – HTML, CSS, JavaScript
• All in one online editor: https://pterocos.eu.org

Perfect for

• Learning a new language without installing anything
• Testing database queries quickly
• Building small web apps with Python + SQLite
• Sharing runnable code examples

What's next?
I am actively adding features. What would make this more useful for you? Faster Python libraries? More database options? Better sharing?
