iTerm2 3.7 released with iOS companion app, Claude Code integration, tab groups, and more

The widely used open-source macOS terminal emulator iTerm2 has released version 3.7, a feature-packed update headlined by a new companion iOS app that puts the terminal in developers' pockets. The companion app, called iTerm2 Buddy, pairs with a Mac by scanning a QR code and communicates over an encrypted Noise channel, with an encrypted relay allowing the Mac and phone to stay connected even on different networks. End-to-end encryption ensures that data remains visible only to the user. Setup has been streamlined into a guided wizard that installs the necessary plugins, handles a single password prompt, and walks users through pairing their phone.

At the heart of the release is a notable expansion of iTerm2's AI capabilities. Alongside the phone pairing, version 3.7 introduces “orchestration”, a new kind of AI chat that can view all of a user's sessions and operate iTerm2 on their behalf, and a Claude Code integration that surfaces a new Session Status feature for Anthropic's coding agent. Sessions can now report status via a control sequence, the it2 command, or triggers, appearing on tabs as a custom subtitle, color, and dot icon, which makes it easy to see at a glance which Claude Code instance is waiting for attention. The integration also works with the new Workflows feature for viewing diffs and code reviews, and ties into clippings so AI-authored code review comments can be sent back to Claude Code directly.

The update also brings substantial organization and workflow improvements beyond AI. Named, colored tab groups, Chrome/Firefox-style, let users collect related tabs under a movable chip, while a new Workgroups feature can automatically spawn a whole cluster of related sessions from a single session, driving AI code review or in-terminal Git diffs. Floating, persistent Session Notes, a screenshot tool with highlights and redactions, and a session archive system that preserves and restores scrollback round out the release. iTerm2 3.7 is available now, with the full changelog on the project's website.
