Managed Deep Agents v0.10: Browser use and asynchronous subagents
LangChain releases Managed Deep Agents v0.10, letting agents work on websites without an API and hand the browser window to a person to sign in. It also adds asynchronous subagents that run long tasks in the background.
What the article says
On October 29, 2026, LangChain announced Managed Deep Agents v0.10, in public beta. It adds two capabilities: browser use, so agents can act on sites that have no API, and asynchronous subagents that work in the background.
The browser runs in its own LangSmith sandbox and exposes tools for reading pages, interacting and taking screenshots. When a login or two-factor step appears, the agent hands control to the user, which keeps passwords out of model messages. For subagents, an "async" setting runs them on their own thread, and they notify the agent when they finish. The release also brings Slack-related changes and breaking changes: connectors.mcp() and the sandbox scope option are removed.
