Managed Deep Agents in LangSmith now hosts a browser for agents and supplies four tools for snapshotting, batch actions, screenshots and handoff to a person, so agents can click, scroll and fill forms instead of relying on APIs. On 100 everyday tasks from WebVoyager on live websites, the toolset passed 90% for $1.98 in total, the highest pass rate among seven toolsets tested; the closest, Browserbase's MCP server, passed 89% at 9x the cost. Browser sessions can be scoped per thread or per user, and an agent can hand the browser to a person at a login page and resume afterward.
