In a comparative analysis of three AI coding tools—Claude Code, Codex, and Google Antigravity—each was tasked with creating a multi-page website for a luxury architectural firm named 'Rajhans.' Codex, despite being set to maximum settings, delivered a basic wireframe lacking visual detail and sophistication, earning a low score due to its slow performance and minimal output. Google Antigravity 2.0, powered by the Gemini 3.5 engine, provided a faster experience and produced a visually appealing black-and-gold theme, though it had some layout issues. Claude Code (Opus 4.8) stood out as the most effective tool, demonstrating a deep understanding of design principles and technical execution, resulting in a premium, image-centric website. While it had minor issues with asset choices, its attention to detail and adherence to semantic HTML earned it the highest score of 9 out of 10, showcasing the significant differences in capabilities among AI developer tools.
