Bobber

A native macOS floating companion for monitoring multiple Claude Code sessions at a glance.

What it does

Bobber sits as a floating panel on your desktop, showing all your active Claude Code sessions in real-time. It watches for events via a Claude Code plugin, displays session status, pending permissions, and lets you jump between terminal windows.

Key features:

• Floating always-on-top panel that doesn't steal focus
• Real-time session monitoring with status indicators (active / idle / blocked / completed)
• Priority system (Focus / Priority / Standard) for organizing sessions
• Permission request cards with approve/deny actions via Unix socket IPC
• Global hotkey (Option+B) to toggle the panel
• Menu bar icon with session count
• Jump-to-terminal for any session

Install

# Clone and build
git clone https://github.com/winrey/bobber.git
cd bobber
swift build -c release

# Copy the built app
cp -r .build/release/Bobber /usr/local/bin/

# Install the Claude Code plugin
cp -r plugins/claude-bobber-plugin ~/.claude/plugins/

Usage

# Run Bobber
swift run
# or after installing to PATH
Bobber

Then start any Claude Code session — Bobber will automatically detect and display it.

Controls:

• Option+B — Toggle panel visibility
• Click a session row — View session details
• Right-click a session — Set priority, rename, or hide
• Right-click a project header — Set default priority for all sessions in that project

Architecture

Sources/Bobber/
├── Models/          # BobberEvent, Session, PendingAction, SessionPriority, BobberConfig
├── Services/        # SessionManager, EventFileWatcher, PermissionServer, HotkeyManager, ...
└── UI/              # FloatingPanel (NSPanel), PanelController, SessionRowView, ...

• Event pipeline: Claude Code plugin writes JSON events to ~/.bobber/events/ → FSEvents watcher picks them up → SessionManager updates state → SwiftUI views react
• Permission IPC: Unix domain socket at /tmp/bobber.sock — plugin sends permission requests, Bobber shows cards, user decides, response flows back
• Zero dependencies: Pure Swift + SwiftUI + AppKit, built with SPM

Requirements

• macOS 13 (Ventura) or later
• Swift 5.9+
• Claude Code CLI
