1212The browser use tool lets Claude navigate, read, and interact with webpages in a browser that your application runs. It works with the page both through its structure (the accessibility tree, elements, forms, and tabs) and through pixels (screenshots and viewport coordinates), whereas the [computer use tool](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool) works with a whole desktop through screenshots and coordinates alone. It's an Anthropic-defined [client toolset](https://platform.claude.com/docs/en/agents-and-tools/tool-use/tool-reference#client-toolsets): one `browser_toolset_20260801` entry in your `tools` array gives Claude 27 member tools by default, such as `navigate`, `read_page`, `left_click`, and `screenshot`, plus four more (`javascript_exec`, `file_upload`, `read_console`, and `read_network`) when you [enable them](https://platform.claude.com/docs/en/agents-and-tools/tool-use/browser-use-tool#enable-optional-member-tools). Your application runs every call against its own browser automation; nothing runs on Anthropic's side. It isn't currently available in [Claude Managed Agents](https://platform.claude.com/docs/en/managed-agents/tools). This page says "your application" for the agent loop that calls the Messages API and "your executor" for the part of it that drives the browser and produces tool results.
