We would love for people to create many labs!
Our system for creating labs runs entirely on the user’s web browser (client side). We do this so that users can immediately start their exercises - they don’t need to install anything, they don’t need to create an account somewhere, and we don’t have to run arbitrary code provided from users on some server.
The current system we implement is called checker.js,
There may be other systems you can also use in the future.
For more about how to create labs with checker, see create_checker.
