Anthropic announced the launch of Claude Code on the web (October 20, 2025), a cloud-based coding agent available in the browser as a research preview. Users can connect to a GitHub repository and describe their requirements in natural language. Claude then handles modifications in a managed, isolated environment, running multiple tasks in parallel. Pull requests are automatically created and change summaries are generated, allowing users to monitor progress in real time and make corrections at any time. This web-based platform complements the existing Claude Code workflow and is designed for managing backlogs, routine fixes, and concurrent development.
Claude Code utilizes sandboxed execution for security: sessions run in an isolated environment, with file system and network isolation. Git operations are proxied through a secure proxy, allowing access only to authorized repositories. Developers can configure accessible domains (e.g., allowing dependencies to be pulled for test runs) and receive notifications and block unauthorized access. A research preview is now available for Pro and Max users, with an early access experience also available on iOS. Cloud sessions share rate limits with other Claude Code usage. Please refer to the official documentation for more details.
Frequently Asked Questions
Q: What is the relationship between Claude Code on the web and the local plugin/terminal version?
A: The web version provides cloud-hosted parallel sessions that complement your local workflow. You can delegate tasks without opening a terminal and still return to your local session when needed.
Q: How do I get started?
A: Connect to the GitHub repository on the web, describe your task, and start a session. Research previews are available to Pro and Max users.
Q: Where is the parallel capability reflected?
A: You can open sessions for multiple repositories or multiple tasks simultaneously in a single interface, track progress independently, and automatically generate PRs and change notes upon completion.
Q: How to ensure safety and compliance?
A: Each task runs in a sandbox with restricted network and file systems. Git can only access authorized repositories through a secure proxy. The domain names allowed for access can be configured as needed.
Q: Is it supported on mobile devices?
A: Yes. During the research preview period, the mobile experience will be available simultaneously on the iOS app, and we will quickly iterate based on feedback.
