A note on this playground

Code runs in your browser using open-source engines (Pyodide for Python, native JS for JavaScript, AlaSQL for SQL). Nothing is sent to OneCity's servers. No accounts, no tracking. If you save your work, copy-paste it somewhere else — refreshing the page resets the editor.
