15541554## Limitations
15551555 
1556* **Platform availability:** Browser use is available on the Claude API and [Google Cloud](https://platform.claude.com/docs/en/build-with-claude/claude-on-vertex-ai).
1556* **Platform availability:** Browser use is available on the Claude API and [Claude Models on Google Cloud (Google managed)](https://platform.claude.com/docs/en/build-with-claude/claude-models-on-google-cloud/google-managed).
15571557* **Whole-input streaming only:** When you stream, each member's `input` arrives as one complete `input_json_delta` ([Client toolsets](https://platform.claude.com/docs/en/agents-and-tools/tool-use/tool-reference#client-toolsets)).
15581558* **Element references are best-effort:** Highly dynamic pages (virtualized lists, canvas-rendered interfaces, pages that re-render on scroll) might not expose stable references, and Claude falls back to screenshots and coordinate clicks there.
15591559* **`read_console` and `read_network` depend on your browser automation:** They report only what it can capture, and only from the moment it attached to a tab.
