JetBrains open-sources ThinkRail, an agentic IDE that gives each coding agent its own git worktree
The Apache-2.0 InnovationHub project wraps the pi coding agent in Monaco tabs, terminals and diffs, runs parallel agents in separate worktrees, and keeps project intent in a graph of SPEC.md files the agent reads and updates. It's an experimental incubator project; install with the one-line script in the repo and run thinkrail (TechNewsReel).
