Why browser-only execution

Praxis Codicis does not send your code to a server. JavaScript, TypeScript, Python, SQL, and Lua run within the tab you are currently viewing, and C/C++ experiments also run separately within the browser.

So running costs are low, and practice records stay on my device. We do not include languages ​​that are difficult to run using just a browser. Rather than pretending that anything is possible, set clear boundaries for what you can do.
