- Its stated benchmark compares memory and CPU across 30 real websites on one 8 GB E2B machine.
Field notes
The site describes a two-live-tab policy: recently used pages stay active in Chromium while the remaining tabs sleep. It says sleeping tabs retain scroll position, form values, history, storage, and login state, and that findInTabs() can search them while asleep. The benchmark section reports tests on an 8 GB E2B machine, including 30 real websites and a run with 10 agents opening tabs at once; those figures are presented by the project.
