Not in model cards

Browser agents complete 2,454 tasks on 452 live websites from the global top 1,000 by traffic. Tasks either read information or write data: creating, updating and deleting records, logging in and downloading files. The board compares browser agent products.

It expands WebVoyager from 15 to 452 sites. The README was last updated in May 2025, and the board ranks agent products rather than models. Live websites change, so results drift over time. The README does not say how runs are graded. About 100 GitHub stars.

Rtrvr AI tops the leaderboard with 81.4%

Best score per entry from the benchmark's own leaderboard, read on November 12th, 2026. Where a model ran with several settings or harnesses, we keep its best. Names in gray aren't in our model list: fine-tunes, agent systems, products and older models. They don't count toward leaders. The best model we track is OpenAI Computer-Using Agent (CUA), at 59.8%.
