Editorial interest 84/100 Selection signal · not a rating of the site

A browser system that gives each agent an isolated Chrome session, shared observation, and a rewindable record of its actions.

Landing page captured for the 2026-08-29 issue.

Field notes

The system separates browser sessions by agent, including cookies, storage, cache, and a lease token intended to prevent cross-session access. Its visible demonstrations cover documentation, programming, news, and testing-oriented destinations across 24 listed sessions. The page describes 38 MCP tools, a shell CLI, and websocket-delivered frames, while screenshots can be returned by reference rather than inserted into an agent’s context.
