Claude Code on the web

Claude Code on the web runs coding tasks remotely in isolated, Anthropic-managed VMs without requiring local setup. Connect any GitHub repository you have access to, describe the work, and Claude autonomously reads code, writes changes, runs tests, and pushes a branch with an auto-generated pull request—all while you're free to work on other things or close your browser entirely.

Core Capabilities:

• Asynchronous Execution: Delegate well-defined tasks that run independently. Start multiple tasks in parallel across different repositories; each runs in its own isolated environment and creates separate PRs when complete.
• Zero Local Setup: Work on repositories you don't have cloned locally. Claude handles environment initialization, dependency installation, and setup scripts defined in your repo configuration.
• Transparent Operation: Monitor progress in real-time through the web interface. Claude shows its complete action plan step-by-step before execution, and you can intervene or provide guidance at any point.
• Configurable Security: Each task runs in a per-task VM with restricted write scope, controlled network access (disabled, allowlist, or broader), and a secure GitHub proxy that keeps credentials out of the execution environment.

Best Use Cases:

• Test-Driven Development: Write comprehensive test suites first, then let Claude implement code to make tests pass. Ideal for backend changes where behavior can be validated automatically (e.g., "Add rate limiting to /api/search with 100 req/min per key—write tests first, then implement").
• Documentation Tasks: Generate or update technical docs, changelogs, API documentation, and code comments. Claude reviews commit history, extracts changes, and follows existing formatting patterns without supervision.
• Scoped Refactoring: Restructure code with clear boundaries—split large files, extract services, organize modules—while test suites validate nothing breaks. The isolated environment lets Claude iterate until tests pass.
• Parallel Bug Fixes: Queue multiple issues from your backlog simultaneously. Each runs independently in its own VM, tackling several fixes at once without manual oversight.

When to Use Web vs. Claude Code CLI in the Terminal:

Use the web for well-scoped tasks with clear requirements that don't need frequent course correction—bug fixes, changelog updates, refactors validated by tests. Use your terminal/IDE for exploratory work, unclear requirements, rapid iteration, or when you need immediate feedback and frequent direction changes. If you realize mid-task you need to provide guidance, use "Open in CLI" to continue interactively.

Security & Environment:

VMs include pre-configured development tools and language ecosystems. Network access is configurable per task. GitHub authentication uses a secure proxy so credentials never exist in the VM. Each environment is destroyed after task completion, ensuring complete isolation between tasks.

Key Developer Benefits:

✓ Batch repetitive work and review later
✓ Contribute to repos without local clones
✓ Run multiple tasks concurrently
✓ Full transparency—see the plan before execution
✓ Seamless handoff to terminal when needed
