October 20, 2025 — San Francisco, CA: Anthropic has announced Claude Code on the Web, a new way for developers to delegate coding tasks directly from their browser. Now available in beta as a research preview, the feature allows developers to connect their GitHub repositories, describe what they need, and let Claude handle the implementation—all without leaving the browser.

Cloud Coding, Simplified

Claude Code on the Web runs entirely in Anthropic-managed cloud environments, enabling developers to launch and track multiple coding sessions in parallel. Each task runs in an isolated sandbox with real-time progress updates and the option to guide Claude’s work mid-session. Once completed, Claude automatically creates pull requests and detailed change summaries.

This setup is designed to accelerate bug fixes, backend refactors, and routine maintenance tasks, while keeping developers in control of higher-level direction.

Flexible Workflows

Anthropic says the web version complements existing Claude Code workflows. It’s especially effective for:

• Understanding project architecture and repository structure

• Fixing small bugs and implementing well-defined tasks

• Running backend changes and using test-driven development (TDD) to verify updates

Developers can also access Claude Code on mobile via the iOS app, making it possible to manage or trigger tasks while away from their main workstation.

Security-First Execution

All Claude Code sessions run in secure sandboxed environments with strict network and filesystem isolation. GitHub interactions occur through a proxy service, ensuring Claude can only access authorized repositories. Developers can optionally configure which external domains Claude can connect to—for example, to install npm packages or run integration tests.

Anthropic emphasizes that this security model protects both code and credentials throughout the workflow.

Availability

Claude Code on the Web is now available to Pro and Max users as part of the research preview. Developers can get started at claude.com/code by linking a GitHub repository and launching their first cloud-based session.

For more details, Anthropic has published technical documentation and an engineering blog explaining its sandboxing and cloud execution model.
