Show HN: I forked JetBrains' new agent IDE to host Claude Code
github.comThinkRail is JetBrains' open-source IDE shell for AI coding agents: worktree-per-tab, chat + file tree + terminal, but hardwired to one agent (Pi).
My fork adds a plugin API so it can host others too, starting with Claude Code running in the same UI.
What's new over upstream:
- A prototype of real plugin system - Claude Code as a first-class citizen — config, IDE bridge, and terminal status all wired in as a builtin plugin, so you get Claude Code sessions in the same worktree-scoped UI as `pi`. - Seven other builtin plugins split out the same way: blueprint (interactive specs), PDF preview, branch graph, a live drawing/visualize surface, and file-type icons
Nightly builds via a Homebrew tap are provided.
