Cursor Background Agent

Overview

Cursor Background Agents run in isolated Ubuntu VMs on Cursor's cloud. Assign a task and the agent clones your repo, creates a branch, writes code, runs tests, fixes lint errors, and opens a pull request, all without you watching. As of early 2026 each agent has a full desktop environment with a browser for UI verification. Up to 8 agents can run in parallel.

Best for
Teams who want to parallelize coding work across isolated cloud environments

Use cases

• Delegate a well-scoped ticket and review the PR later while staying in flow on something else
• Run parallel agents on independent bug fixes or feature branches simultaneously
• Let an agent do the implementation grunt work overnight and review the diff in the morning
• Visually verify UI changes by letting the agent open a browser and click through the app

Notes

Why it matters

Background Agents are Cursor’s answer to asynchronous autonomy. The rest of the AI editor market still ties the agent to your open IDE session. Background Agents run in the cloud, ship a PR, and let you review it on your own schedule.

How teams use it in production

The pattern that works: write a scoped, self-contained task brief with clear acceptance criteria. Assign it to a Background Agent. Review the PR diff, not the step-by-step. Use standard code review processes, the agent branch is just another branch.

What to watch

The per-task VM model is the right isolation primitive for agent work. The question is how Cursor extends it: multi-agent coordination, shared tool state across VMs, and richer approval checkpoints are all on the roadmap.
