WebsiteBench: Can AI Agents Rebuild Websites Through Browser Exploration?

WebsiteBench is a benchmark in which agents explore a production-level website through a browser and must reverse-engineer a full-stack version matching its appearance and behavior as closely as possible. The repository provides quickstart instructions using uv, Docker, and the harbor run command to evaluate single tasks from local-tasks/ or all tasks, with results written to jobs/.
