manaflow-ai/cmux is a Ghostty-based macOS terminal with vertical tabs and notifications for AI coding agents. According to the collected records, the latest release is v0.65.2. No changelog is given for this version, so what was added remains unverified.
The project focuses on organizing multiple agent tasks on a single screen. Vertical tabs are a way of stacking tabs vertically, and notifications tell you when agent work is proceeding outside the foreground. The README states that you can launch a browser beside the terminal, and that it supports SSH, Claude Code Teams, a notification panel, and a scriptable CLI and socket API. The repository description calls the app a tool for multitasking, organization, and programmability. It is a native open source app built with Swift and AppKit, and the GitHub star count is recorded as 28318. The repository was created on January 28, 2026.
There is, however, a lot that could not be verified. The license is shown only as NOASSERTION, so the actual terms of use are unknown. The novelty, technical, and quality scores are empty, and only the momentum score remains, at 6.0. There is also no material showing how well the features listed in the README actually work. The only thing that can be confirmed from these records is that this is a macOS desktop tool that brings AI coding agents together in one place.
