218218| `bridge.claudeusercontent.com` | [Claude in Chrome](/docs/en/chrome) extension WebSocket bridge |
219219| `*.frame.claudeusercontent.com` | [Artifact](/docs/en/artifacts) content reads. The CLI fetches an artifact's files from this host when Claude opens one, and only when the Artifact tool is [available](/docs/en/artifacts#availability) for your account. To turn the tool off and drop this requirement, set [`"enableArtifact": false`](/docs/en/settings-reference#enableartifact) or [`CLAUDE_CODE_DISABLE_ARTIFACT=1`](/docs/en/env-vars); Claude Code also honors the deprecated [`disableArtifact`](/docs/en/settings-reference#disableartifact) setting. See [Disable artifacts](/docs/en/artifacts#disable-artifacts) for how these settings interact |
220220| `raw.githubusercontent.com` | Changelog feed for [`/release-notes`](/docs/en/commands). In interactive sessions, Claude Code also fetches it in the background at startup when its cached changelog doesn't yet cover the running version, such as the first start after an update; non-interactive and cloud sessions never fetch it |
221| `*-review.googlesource.com` | Gerrit change lookup on `googlesource.com` checkouts. When a Claude Desktop Code tab session starts or resumes on a [trusted](/docs/en/permissions#project-allow-rules-and-workspace-trust) checkout whose `origin` is a `googlesource.com` host, Claude Code asks that host's `-review` server anonymously for the open change matching HEAD's `Change-Id`, once per start or resume. Other session types skip the lookup, and no other Gerrit host is contacted. Optional: disable with [`CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC`](/docs/en/env-vars) |
221222| `http-intake.logs.us5.datadoghq.com` | Operational telemetry events, sent only when the CLI uses the Anthropic API directly, never for Amazon Bedrock, Google Cloud's Agent Platform, or Microsoft Foundry. Optional: disable with [`DISABLE_TELEMETRY`](/docs/en/data-usage#telemetry-services) or `DO_NOT_TRACK` |
222223| `browser-intake-us5-datadoghq.com` | Operational error reports, sent when the CLI uses the Anthropic API directly and a server-side rollout gate enables them. Optional: disable with `DISABLE_ERROR_REPORTING` or `DISABLE_TELEMETRY`; see [Telemetry services](/docs/en/data-usage#telemetry-services) |
223224| `formulae.brew.sh` | Update version checks on Homebrew installs. Other install methods don't contact this host |
