Hi everyone, I built Pterocos (https://pterocos.eu.org) - a free online editor that runs Python (plus C#, Rust, Ruby, SQL, Lua) entirely in your browser. No installation, no account required. **Why this might be useful for educators:** - Students can start coding immediately - no local setup - Zero cost - completely free, no premium version - Runs on any device with a browser (Chromebooks, school computers, tablets) - Perfect for teaching Python basics, data structures, or algorithms - Also supports SQL (SQLite/DuckDB) for data science teaching The editor runs entirely client-side - your code never leaves your browser. No tracking, no ads, no sign-ups. Try it: https://pterocos.eu.org I'd love feedback from educators! How could this tool better serve your teaching needs? Thank you, Amine KHD
