Rig
Gives each coding agent, such as Claude Code, Cursor or Codex, its own cloud Linux desktop with a running dev server, tests and a signed-in Chrome, so the developer's laptop stays free while several agents work at once.
Rig gives each coding agent a Linux desktop in the cloud that already has the project's code, a running development server, tests and a Chrome browser signed in to the developer's own accounts. The coding agent itself keeps editing code on the developer's laptop; the heavier surrounding work, such as running a dev server per branch, checking the UI in a browser, or running tests, moves into that cloud desktop instead, so several agents can run at once without the laptop slowing down.
A cloud desktop pauses automatically after a period of inactivity and wakes again in a couple of seconds, and one command copies browser logins from the developer's own Chrome, Arc, Edge, Brave, Firefox or Safari profile into every new desktop it creates. The agent can also use computer use and Model Context Protocol tools to see the whole screen and click, type and take screenshots, and the developer can open the same desktop's screen in a browser tab at any time to finish a login or enter a two-factor code.
