Hangar

A terminal session manager for Claude Code — built for engineers who live in git worktrees.

---

Features

Live Session Monitoring

Every Claude session shows real-time status — running ●, waiting ◐, or idle ○ — updated instantly via Claude Code lifecycle hooks.

PR Badges & Overview

Worktree sessions with open PRs display color-coded badges in the sidebar (green = open, purple = merged). Press P for a full-screen PR dashboard with CI check status.

Inline Diff View

Press D to open a pager-style diff overlay for any session's working directory — scroll, page, and jump to hunks without leaving Hangar.

Todo Kanban Board

Press t to open a per-project kanban board with todo → in progress → in review → done columns. Press Enter on a card to spin up a new Claude session + worktree for that task.

Worktree-First Workflow

Every new session automatically creates a git worktree from the latest base branch. Press W to merge, clean up, and close in one step.

Send Text Without Attaching

Press x to send a message to any session — no attach/detach needed.
