Claude Code on the web: how cloud sessions work, and when a shared space fits better

Claude Code on the web runs sessions in Anthropic's cloud. How to start one, move it to your terminal, share it, and when a Mirasim team space fits better.

The short answer

Claude Code on the web, at claude.ai/code, runs Claude Code sessions on infrastructure Anthropic manages instead of on your computer. A session keeps going after you close your laptop, you can check on it from any device, and it works on GitHub repositories. Cloud sessions are available on Pro, Max, Ultra and Team plans, and they count toward your plan's usage limits.

How cloud sessions work

Start one
At claude.ai/code, in the Code tab of the Claude app, by choosing a Cloud environment in the Claude desktop app, or with claude --cloud "task" in your terminal
Bring it to your terminal
claude --teleport pulls a cloud session into your terminal. It's one-way: an existing terminal session can't be pushed to the cloud
Environment
Each session runs in a cloud environment that sets network access, environment variables and setup scripts; a Default one is set up for you
Code hosting
Cloning and pull requests in Anthropic-hosted environments need GitHub; GitLab or Bitbucket repositories can be sent as a local bundle
Pull requests
Auto-fix can watch a pull request and respond to review comments and CI failures

Questions

Is Claude Code on the web free?
No. Cloud sessions come with Pro, Max, Ultra and Team plans, and Enterprise premium or Chat + Claude Code seats. They count toward the same usage limits as your other Claude usage.
What's the difference from Remote Control?
A cloud session runs on Anthropic's infrastructure. Remote Control lets your phone or browser reach a session that runs on your own computer.
Can teammates work in my cloud session?
They can open a shared link and see its latest state. In a Mirasim team space, teammates send messages into the same session as it runs.
Can a team share my Claude plan in Mirasim?
A personal Claude subscription is for its owner only, so a session your team shares runs on a shared key or space credit.
