## Best for

Developers running several coding agents in parallel who want isolation without leaving the IDE.

## Why it deserves attention

ThinkRail opens a repo as a project and cuts workspaces as real git worktrees, each with its own branch, files, terminals, and chat, so several agents can work without touching your main tree. The pi agent runs in-process across Monaco tabs, diffs, and a spec graph it reads and maintains. It is Apache-2.0 from JetBrains InnovationHub, has 7,000+ GitHub stars, and the Mac build is available now. It is early, so expect rapid changes and a much smaller extension ecosystem than VS Code.
