One hotkey.
Every session in the air.
Juggler is a native macOS app that tracks your running coding agent sessions and cycles you to the next one that needs attention. No workflow changes. No new terminal.
brew install --cask nielsmadan/juggler/juggler
Press the hotkey. Land on the next idle session. Keep juggling.
Instant switching
Press one global hotkey from anywhere — any app, any Space — and Juggler takes you straight to the next session that's waiting for input.
Never lose a window
When you switch, Juggler highlights the terminal tab and pane with a color-coded flash. Across multiple monitors, you'll spot it immediately.
Zero workflow changes
No new terminal to learn. No forced worktrees. No limit to one repo. Keep your existing setup and workflow.
Running in two minutes.
Install
Grab the .dmg or install with homebrew.
Onboarding
Juggler guides you through granting Accessibility permissions, setting up your terminal integration, and installing the hooks that let it detect sessions.
Open your sessions
Start Claude Code or OpenCode sessions as you normally would. Juggler detects them automatically. No registration. No config.
Hit the hotkey
Press ⇧⌘K and you're at the next idle session. That's it.
What's in the box.
Global hotkeys
Cycle forward, backward, backburner, reactivate, toggle the UI. All global, all customizable.
Tab & pane highlighting
Color-coded flash marks the active session's tab and pane. Spot it instantly across monitors.
Notifications
Native macOS alerts when a session goes idle or needs permission. Click to jump there.
Menu bar & monitor
Popover for a quick glance. Full session monitor with all the details and jugglery animations.
Queue modes
Fair, Priority, or Static. Match Juggler to your tasks and your workflow.
Backburner
Park sessions you don't need right now. They stay tracked but skip the cycle. Reactivate when you're ready to continue
Idle time stats
Per-session and global idle vs. working time. See your actual throughput.
Guided setup
Onboarding walks you through permissions, terminal integration, and hooks. No manual config.
Hands stay on the keyboard.

Terminals
Coding agents
Requires macOS 14.0+ (Sonoma).
More integrations — WezTerm, Gemini CLI, Copilot — coming soon.
Your terminal. Your way.
Other session managers
Wrap sessions in a TUI or separate app. Give up splits, profiles, scrollback. Force tmux. Force worktrees. Limit to one repo. And who knows how long they will be maintained?
Juggler
Sits in your menu bar. Detects sessions via hooks. Activates your real terminal windows natively. Your workflow stays exactly as it was.
Stop hunting for idle sessions.
Free, open source, and built for people who run coding agents all day and hate using their mouse.
