Hi! Iâm Gabriel! I made DEMOLAND! Iâm a designer, developer, and teacher. I made DEMOLAND to make learning and writing code less scary for my students.
DEMOLAND lets you read, write, and test code without leaving your web browser. This site features âbooksâ containing collections of code demos.
I built DEMOLAND for creative people interested in code! DEMOLAND is a place to start experimenting with code without worrying about if itâs 100% âcorrectâ or the best it can be.
YES IT IS!!!! Itâs more important than ever to learn how to code now that AI exists. This is because youâre now much more likely to use code than ever before! But regardless of if youâre coding by hand or prompting, you need to understand how code works, how to read it, and how to edit it.
In 2023, I started DEMOLAND and coded the first few versions by hand (with help from the CodeMirror library). I rebuilt DEMOLAND in 2026 with a greatly expanded featureset, which I was only able to achieve through the help of AI. I have many conflicted feelings about AI and avoided it for many years. I started using it in 2026 because my students were using it, and while I have many conflicted feelings about its many costs (ethical, environmental, etc.), I would not have been able to build this version of DEMOLAND without it.
DEMOLAND is part of GD with GD. If you want to get in touch, reach out to me (Gabriel)!
