Claude Code Complete Guide

Claude Code Web Explained – Browser-Based Cloud IDE for Delegating Development

What is Claude Code Web?

Claude Code Web is Anthropic’s cloud-executed coding environment introduced in October 2025. Built on Claude Artifacts, it lets you trigger code generation, testing, documentation, and pull-request creation directly from a browser or the Claude iOS app—no local setup required1.

Key Capabilities and Benefits

Capability snapshot

  • Cloud execution: Tasks run inside Anthropic-managed sandboxes that install dependencies, run tests, and produce PRs without touching your local machine.
  • Parallel task management: Launch multiple requests across different repositories simultaneously. Each task ships a dedicated pull request, helping you burn down maintenance queues quickly.
  • Mobile-ready workflow: The same interface is available in the Claude iOS app, so you can approve or adjust work while traveling or away from your laptop.
  • Artifacts integration: Reuse Claude Artifacts to generate UI mockups, documentation, or design systems, and feed them straight into your code tasks.
  • Secure delegation: gVisor-class sandboxing keeps network and filesystem access constrained to approved resources, protecting credentials and proprietary code.

Typical Use Cases

  • Fixing bugs and maintenance chores: Point Claude to issues with reproduction steps and let it deliver tested fixes and PR summaries.
  • Repository discovery and documentation: Ask Claude to explain service architecture, summarize dependencies, or audit configuration files.
  • Refactoring and modernization: Coordinate bulk updates across multiple repositories with clear, separate pull requests.
  • Mobile hotfixes: Launch emergency tasks or review PRs from your phone when you’re away from the office.

How It Differs from Other Tools

The desktop/CLI version excels at custom toolchains and low-latency tweaks, but requires local environment prep. The web version removes setup overhead and hardware constraints.

Claude Code Web standardizes end-to-end task execution—prompt in requirements, receive a tested PR. It also integrates with Artifacts and supports full mobile usage.

Fine-grained sandbox controls, laws directives, and Agent Skills let you tailor behavior while keeping code execution confined to approved resources.

Security and Control

According to Anthropic’s announcement1: - Every task runs inside an isolated sandbox; network and filesystem access require explicit allowlists. - GitHub interactions move through an Anthropic proxy, so access tokens never leave your control. - You can specify permitted domains (for npm, PyPI, internal package mirrors, etc.) to unblock necessary downloads. - Task history and logs can be exported for audit trails that align with internal security policies.

Pricing and Availability

  • Eligible plans: The research preview is available to Claude Pro and Max subscribers. Team and Enterprise rollouts will follow.
  • Usage quotas: Web tasks share the same rate limits as the wider Claude Code offering. If you plan to queue multiple parallel runs, Max is recommended.
  • Supported devices: Modern Chromium- and WebKit-based browsers plus the Claude iOS app. Android support is on Anthropic’s roadmap.

Getting Started: From Setup to PR

Step-by-step walkthrough
  1. Visit claude.com/code and sign in with your Claude Pro/Max account.
  2. Click Connect a repository, authorize GitHub access, and pick the repo and branch you want to automate.
  3. Describe the task—include goals, acceptance criteria, tests to run, or laws that guide the agent’s behavior.
  4. Monitor the live execution log in your browser and redirect the workflow if Claude needs clarification.
  5. Review the resulting PR: you’ll get a diff summary, test results, and contextual explanations ready for merge.
  6. Install/update the Claude iOS app to queue or monitor tasks when you’re away from your desk.

Frequently Asked Questions

Can I try Claude Code Web for free?

You’ll need a Claude Pro or Max subscription. During the research preview there’s no additional fee, and usage counts against your existing Claude Code limits.

How does it work with my CI/CD?

Claude creates pull requests that then trigger your existing CI pipelines. If tests fail, you can feed the logs back to Claude Web to request a fix and resubmit.

Is it safe for private or government repositories?

Only approved repositories and domains are accessible, and everything runs inside constrained sandboxes. Pair this with org-level GitHub controls and audit logs for compliance-heavy environments.

Do I have to abandon Copilot or Codex?

No. Many teams pair Claude Code Web for bulk automation with Copilot/Codex for in-editor assistance or review automation.
