Anthropic has added a built-in browser to Claude Code. The tool can now access websites directly, rather than being limited to local development servers. This lets Claude look up documentation, review designs, or browse any other web content while working on a task.
Sandbox by Default
The browser runs in a sandboxed environment. Sessions are not persisted by default, and users choose whether to retain browser state between tasks. Each session starts with a clean profile: no saved logins, no history from the user's personal browser. This setup works well for building and testing applications, or for any site where user identity is not needed.
For cases where Claude needs to act on behalf of the user in authenticated sessions, Anthropic points to the separate Claude extension for Chrome. That extension trades some isolation for access to logged-in applications.
An Industry-Wide Shift
OpenAI has simultaneously announced it is shutting down its standalone ChatGPT Atlas browser and moving that capability into an internal browser inside the ChatGPT desktop app. Both companies also maintain their own Chrome extensions. The direction is clear: tighter browser integration directly inside AI development tools. For developers using FameSystems hosting and working with Claude Code, this means more flexibility when testing deployments right from within the development environment.
