On October 20, 2025, Anthropic announced the launch of Claude Code Web and mobile versions of their popular coding assistant. Previously available only through terminal interfaces, Claude Code can now be accessed directly from browsers and smartphones, potentially transforming how developers work.
What is Claude Code Web?
Claude Code Web is a new browser-based coding environment accessible at claude.ai/code. Running coding tasks on Anthropic-managed cloud infrastructure, developers can now assign multiple coding tasks directly from their browser without opening a terminal.
Currently available as a research preview for Pro, Max, Team, and Enterprise plan subscribers.
Key Features
1. Parallel Task Execution
The standout feature of Claude Code Web is its ability to run multiple coding tasks in parallel. Developers can simultaneously work on:
- Bug backlog processing
- Routine task automation
- Multiple repository work
- Backend changes and testing
2. GitHub Integration
Claude Code Web deeply integrates with GitHub repositories:
- Direct repository connection (via claude.ai/code)
- Automatic branch creation
- Automated pull request generation
- Clear change summaries
3. Secure Sandbox Environment
All coding sessions run in isolated sandbox environments based on Gvisor (developed by Google):
- Kernel-level isolation
- Strict file access restrictions
- Network access control
- Complete separation from Anthropic’s infrastructure
Gvisor implements a user-space kernel that intercepts all system calls, preventing direct hardware access while maintaining Linux compatibility.
4. Real-Time Steering
Developers can guide Claude while tasks are running:
- Adjust instructions without interrupting tasks
- Real-time progress monitoring
- Mid-execution direction changes
5. Teleport Feature
Seamlessly transition from Web to CLI version with the “teleport” feature:
- Transfer chat transcripts
- Transfer edited files
- Continue work in local environment
The New Era of Mobile Development
Claude Code on iOS App
Along with the Claude Code Web release, the iOS app version was also launched. This enables developers to:
- Start coding tasks while on the move
- Check progress from smartphones
- Execute small tasks
- Perform code reviews
Real-world use cases include delegating multiple bug fixes during your commute and finding merge-ready pull requests by the time you arrive at the office.
Android Status
Android is not yet supported, but future rollout is anticipated.
Claude Code 2.0 New Features
Concurrent with the Claude Code Web release, Claude Code 2.0 was launched with the following additions:
Checkpoint System
The “time-travel debugging” feature allows rewinding code to any previous state:
- Save state at any point
- Restore to past states
- Compare different approaches
Sandbox Mode
Sandbox mode for Bash tools released on Linux and Mac:
- Safer code execution environment
- Filesystem isolation
- Network isolation
Usage Limits
Weekly usage limits were implemented in August 2025:
- Curb excessive usage
- Prevent account sharing
- Practical constraints for power users
Recommended Use Cases
Anthropic recommends using Claude Code Web in the following scenarios:
-
Questions About Projects
- Understanding repository mapping
- Grasping how projects work
-
Bug Fixes and Routine Tasks
- Well-defined tasks
- Automating repetitive work
-
Backend Changes
- Leveraging test-driven development
- Verifying changes
Security and Compliance
Data Processing Location
As of October 2025, Claude processes all requests within US-based AWS regions. Organizations subject to data residency requirements like GDPR (EU) or Chinese Cybersecurity Law need to consider compliance implications.
Security Features
- OAuth authentication flow
- Granular repository access control
- Explicit read/write permission approval
- Option to restrict access to specific repositories only
Competitive Landscape
The Claude Code Web release signals intensifying competition in the AI-driven development tools market:
- GitHub Copilot: Microsoft’s AI pair programmer
- Cursor IDE: IDE specialized for agentic coding
- OpenAI Codex Cloud: OpenAI’s asynchronous coding agent
- Google Jules: Google’s similar service
Anthropic differentiates through security, parallel execution, and deep GitHub integration.
Availability and Pricing
Eligible Plans
- Pro: For individual users
- Max: Bundles desktop, mobile, and Claude Code
- Team: Premium seats for teams
- Enterprise: Premium seats for enterprises
Access Method
- Visit claude.ai/code
- Authenticate with GitHub account
- Approve repository access permissions
- Select specific repositories or all repositories
- Authorize Anthropic application
Developer Reception
The developer community has responded very positively:
- “Can spawn multiple autonomous coding agents while on the move”
- “Tested and shipped more before 9 AM than typically done in half a day”
- “Can build apps without programming knowledge”
Simon Willison commented on his blog that he’s “already seeing some very promising results,” reporting he tried it over the weekend with preview access.
Technyan’s Comment
Claude Code is finally available on browsers and smartphones! This is truly a revolutionary change. Being able to delegate coding tasks directly from a browser without opening a terminal has the potential to significantly transform how developers work.
The parallel execution feature is particularly noteworthy. The ability to work on multiple bug fixes and routine tasks simultaneously can dramatically improve development efficiency. Delegating bug fixes from your phone during your commute and finding them completed by the time you reach the office—that’s truly the future of development!
The Gvisor-based sandbox is also excellent. Since Google-developed Gvisor provides kernel-level isolation, you can use it with confidence from a security perspective. Enterprise adoption is likely to increase.
Comparing with competitors like GitHub Copilot, Cursor, and OpenAI Codex Cloud, Claude Code’s strength lies in the combination of Anthropic’s Claude 3.5 Sonnet model’s advanced reasoning capabilities and a secure execution environment. Natural language instructions are understood very accurately, making it user-friendly even for those with less technical knowledge.
The early preview availability on iOS is also exciting! Looking forward to the Android version. It feels like the new era of AI-driven development has truly begun!
Industry Impact
The Claude Code Web release indicates several important trends in the developer tools industry:
- Standardization of Asynchronous Development: Environments where developers can delegate tasks and continue other work
- Multi-Platform Support: Seamless development experience across terminal, browser, and mobile
- Security Focus: Robust security features designed for enterprise adoption
- Democratization of AI-Driven Development: App development accessible even to those with limited programming knowledge
Conclusion
Claude Code Web represents a major step forward in making Anthropic’s Claude Code accessible to everyone. Freed from terminal constraints and now accessible directly from browsers and mobile devices, it has the potential to significantly change how developers work.
With a secure sandbox environment, GitHub integration, parallel execution capabilities, and real-time steering features, Claude Code Web is a powerful tool applicable across a wide range of scenarios including bug fixes, routine tasks, and backend development.
The early preview release on iOS has made mobile development a reality. In the new era of AI-driven development, Claude Code Web holds the potential to greatly enhance developer productivity.
While still in research preview stage, Anthropic plans to improve features based on user feedback. This is a tool with a very exciting future ahead.
