(2025-10-20) Vibe Check Claude Code Now Works On Mobile And The Web

Vibe Check: Claude Code Now Works on Mobile and the Web. I’ll admit that I've been using OpenAI's Codex for most of my coding lately, but Kieran still swears by Claude Code, running multiple instances in parallel as part of his compounding engineering workflow. So when Anthropic gave us early access to the cloud and mobile version of Claude Code that just launched, we all carved out time to test the same promise: Can you actually run Claude Code from your phone? Can you assign it a coding task while you're away from your desk and pick it up later? Does "anywhere" truly mean anywhere?

the dream is being able to kick off a Claude Code session on my laptop and then keep it running in the cloud when I go to a meeting. So my question was: Is Anthropic's cloud and mobile version the one that finally delivers? Short answer: Not yet.

getting the cloud environment to handle our setup was a pain, the mobile app lacks important features like inline code diffs, and most importantly, you can’t kick off a task on your computer and then transition it to the cloud.

A caveat: This version is a work in progress. Anthropic is leaning into AI's new normal—ship early, iterate fast, improve in public. What we tested will likely be better by the time you read this.

The cloud and mobile version of Claude Code is Anthropic's answer to remote coding. Like OpenAI’s coding agent Codex, it promises to spin up virtual machines in the cloud with your codebase, letting you delegate coding tasks without keeping your laptop open.

It boots up a cloud environment with your repository, sets environment variables (like which domains it can access), and starts working. You can watch its progress, see its to-do list, and—here's where it differs from Codex—keep chatting with it while it works. In Codex, you have to stop execution to talk to the agent. Claude Code's interface treats it as an ongoing conversation.

Normally, when you run Claude Code on your laptop, the AI needs your computer to stay on and connected; it's using your machine's processing power and your local copy of the code. "Cloud" means Anthropic runs everything on its remote servers instead. Your code lives there, the AI runs there, and the work happens whether your laptop is open or not. You can check progress from your phone, pick up where you left off from a different computer, or just walk away while Claude keeps working.

If Claude Code Cloud could nail both—let you chat with it mid-execution and deliver a mobile experience that works—it would solve the two biggest pain points in the category.

For this vision to deliver on its promise, it needs a few core ingredients:

In practice, almost every one of those core ingredients Claude Code needs to bring this promise to life breaks down when you try to use them.
