Web Agent Benchmarks: WebArena, WebVoyager, Mind2Web and More (2026)

Browser Use has published a guide to web agent benchmarks, comparing what they test and how they score it.

It separates controlled sandbox tests such as WebArena, live-site tests such as WebVoyager, and offline datasets such as Mind2Web that compare predicted steps with recorded human actions. The guide also points to benchmarks for screenshot-based agents, deep research and enterprise workflows.

Scores need context: Browser Use says changing only the judge model on the same 104 finished runs produced scores from 62.5% to 83.7%. Its advice is to run your own real tasks more than once rather than choose an agent by a public score alone.
