The Current State of Browser Agents
summary
Web Bench benchmarks browser agents across 450+ sites with ~5,000 read and write tasks and shows concrete numbers: about 80% success on read tasks, fully autonomous write tasks fall roughly 50%, and a substantial gap to an operator with human oversight (~75–80%). Results attribute failures to both agent mistakes and infrastructure limits (captcha, login, proxies) and note agents are often usable but painfully slow for real‑time workflows.
