Code Arena

Choosing an AI coding model is easier when you can see how different models handle the same task. Code Arena, formerly known as LMArena, lets developers enter one prompt, generate multi-file applications or websites side by side, and compare leading models' code quality, reasoning and accuracy in real time.

Once you have compared the results, you can export ready-to-run code directly to GitHub or a local IDE and continue working with it in your own project. The platform also turns screenshots and mockups into functional code through its Image to Code feature, while a leaderboard helps you track how different AI models perform and make sense of the available choices.
