About Code Arena
Code Arena — Code Arena, formerly known as LMArena, is a professional platform designed for developers to test and compare top AI coding models side-by-side. By entering a single prompt, users can generate multi-file applications or websites and evaluate the quality, reasoning, and accuracy of different AI models in real time. The platform supports exporting ready-to-run code directly to GitHub or a local IDE. It also features 'Image to Code' capabilities, allowing users to transform screenshots or mockups into functional code, and includes a leaderboard to track the performance of various AI models.
