Mirasim vs Cursor Cloud Agents

Cursor Cloud Agents run Cursor's agent in cloud VMs and hand back pull requests. Mirasim hosts a space where your team steers Claude Code, Codex and others together.

The short answer

Both keep agents working while your computer is off. Cursor Cloud Agents start Cursor's agent in a cloud virtual machine from Slack, GitHub, Linear, the web or your phone, and hand the work back as a branch or pull request. Mirasim hosts a team space where your coding agents stay on and several people steer the same session together.

What are cloud agents?

Cloud agents, also called background agents, are coding agents that run on a remote machine instead of your laptop. You hand them a task, close the lid, and come back to a branch, a pull request or a finished session. Cursor Cloud Agents, Codex Cloud and Claude Code on the web are vendor-run versions. In Mirasim the remote machine is a space your team shares: a team space we host, or your own server.

What Cursor Cloud Agents do well

  • Start a task from wherever the request shows up: a Slack thread, a GitHub or Bitbucket comment, a Linear issue, or the API.
  • Each agent gets a full development environment, set up by the agent, from a snapshot, or from a Dockerfile.
  • Agents return screenshots, videos and logs of what they changed, and you can take over the agent's remote desktop to try the software.
  • Run as many as you like in parallel, without your computer online.

What Mirasim does well

  • Run the agents themselves, unmodified: Claude Code, Codex and eight more, each on its own sign-in, or on Mirasim credit.
  • A shared, live session: teammates watch the same turn and send into it, instead of each reviewing a separate pull request afterwards.
  • The same space from the desktop app, the phone apps and a browser.
  • Start on your own computer for free, and move to a team space when you need it to stay on.

Questions

Can I run Claude Code in the cloud with Mirasim?
Yes, in a team space we host, and it keeps running after you close your laptop. A personal Claude subscription is for its owner only, so a session your team shares runs on a shared key or space credit.
Can Mirasim run Cursor's agent?
No. Mirasim runs Claude Code, Codex, Kimi Code, DeepSeek Harness, OpenCode, Qwen Code, Pi, Antigravity, ZCode and Grok Build.
Do I need my computer on?
Not for Cursor Cloud Agents or a Mirasim team space. If you run Mirasim on your own computer instead, it has to stay on and awake.
