What you'll learn

Your terminal is your entire IDE when using Claude Code. This video compares iTerm2 (the battle-tested veteran) with cmux (the new agent-first challenger) and shows you when to use each one.

cmux brings features no traditional terminal has: vertical workspace tabs showing git branch, PR status, and listening ports. A 4-tier notification system with blue pane rings, sidebar badges, popovers, and macOS alerts. A built-in WebKit browser for localhost preview. And a socket API that lets agents control their own workspace.

🔑 Key takeaways:
• iTerm2: Deep search, mature features, rock-solid stability, universal compatibility
• cmux: Agent notifications, workspace metadata, built-in browser, socket API
• When to use iTerm2: General dev work, search-heavy workflows, mixed AI + manual coding
• When to use cmux: Multi-agent sessions, full-stack with localhost preview, heavy Claude Code usage
• Power user tip: Use both — iTerm2 for general work, cmux for agent sessions

cmux is free, open source (AGPL), and reads your existing Ghostty config. Download from cmux.dev.
