GitHub's Copilot app runs several coding agents side by side

The GitHub Copilot app is built around running several coding agents at the same time. Each session runs in its own git worktree, a real, isolated copy of your branch. Agents can work in parallel without breaking each other's changes, and the app sets up and cleans up every worktree for you.

GitHub's own example runs three tasks at once in one repo: building a new sort feature, doing an accessibility review and running the test suite. A single sessions view shows how each one is doing. Each session also keeps its own context, so you can switch between them without explaining the task again. The agents don't share one brain. They're separate workers, and you're the one who merges their work. In GitHub's words, your time goes to "reviewing and making decisions" instead of watching each step.

The app launched in technical preview at Microsoft Build on June 2 and opened to every Copilot plan on July 7, including Copilot Free and GitHub Education. GitHub suggests trying it first with two small tasks.

Why it matters: the developer's job is moving from writing code to reviewing it, and isolated worktrees are what let you run several agents at once without merge chaos.
