Anthropic brings Claude Code to the browser as a research preview
Anthropic has launched Claude Code on the web, a beta research preview that enables coding tasks to be delegated directly from the browser and executed on Anthropic-managed cloud infrastructure. The web interface lets users connect GitHub repositories, describe the work to be done, and run multiple coding sessions in parallel without opening a local terminal.
Parallel cloud sessions and developer workflow
The web experience is designed to let Claude start and manage coding sessions across repositories from a single interface. Each session runs in its own isolated environment with real-time progress tracking, and interactive steering is supported so tasks can be adjusted while Claude is working. The system can create pull requests automatically and produces concise change summaries, enabling faster iteration across simultaneous tasks.
The web interface is presented as a complement to existing Claude Code workflows. It is particularly suited for scenarios such as answering questions about repository structure and mappings, handling bug fixes and well-defined routine tasks, and performing backend changes where test-driven development can be used to verify updates. An early preview of Claude Code is also available on the iOS app as part of this research preview.
Security-first sandboxing and network controls
Every cloud task executes inside an isolated sandbox with network and filesystem restrictions. Git interactions pass through a secure proxy that restricts access to authorized repositories, aiming to keep code and credentials protected throughout the workflow. Custom network configuration options are available to control what domains a sandboxed session may reach; for example, domains required to download npm packages can be allowed so tests can run and changes can be validated. For technical detail, refer to Anthropic’s engineering blog and the sandboxing documentation:

Availability and limits
Claude Code on the web is available now in research preview for Pro and Max users. Access is provided at claude.com/code to connect repositories and begin delegating tasks. Cloud-based sessions share rate limits with other Claude Code usage; further operational details are in the product documentation: https://docs.claude.com/en/docs/claude-code/claude-code-on-the-web
