Welcome to CraftNova
What is CraftNova?
CraftNova is a free platform for playing and sharing browser games made with AI.
Every game is a single HTML file that runs right in your browser, so there's nothing to install. Open a game on your phone or PC and start playing in seconds.
Made with AI, by everyone
You don't need to know how to code. Describe the game you want to ChatGPT, Claude, Gemini, or any other AI, and it can write the whole thing for you.
Before you start, paste the guidelines from the posting page into the chat. They tell the AI how to build a game that fits any screen and runs safely on CraftNova.
Safe to play
Every game runs in an isolated sandbox. Games can't read your account, your cookies, or anything else on the site, and they can't send data anywhere. That's why you can try games from people you've never met without worrying.
Stream and share freely
All games on CraftNova are OK to stream and record.
Upload your playthroughs to YouTube, share your high scores on X, and help great games find more players.
Now in beta
CraftNova is in public beta and is run by a small team in Japan. Games from both Japanese and English-speaking creators appear here, and games marked "All Countries" are shown on both sites with AI-translated titles.
If you find a bug or have an idea, let us know through the contact form. Rankings are coming in the full release.
During the beta, you may run into unexpected behavior or unannounced maintenance. Thanks for your patience.
