cmux

--- Lawrence Chen, Austin Wang, Mike Staub, Kevin Li, David Chu, Max Metcalfe, and Desen Meng looked at every terminal emulator out there—iTerm2, Hyper, Warp, Ghostty—and realized something: they're all built for humans. Every single one. But the future of coding isn't just human-centric—it's agent-centric. So they built cmux, the first terminal actually built for AI coding agents.

Here's the thing: AI coding agents are exploding. Devin, Cursor, Windsurf, Claude Code—they're all trying to automate software development. But they still need a terminal to execute commands, run scripts, and interact with development environments. The problem? Existing terminals don't understand agents. They don't optimize for agent workflows. They don't give agents the UI they need. cmux fixes that. It's Ghostty-based with vertical tabs and notifications specifically designed for how AI agents work—because apparently no one else thought to build a terminal that speaks fluent AI.

This is open-source, which means the community gets to shape where it goes. And given that Manaflow AI built this, they're clearly thinking about the agent infrastructure layer in a way most people aren't. Every developer tool is racing to add "AI features." Manaflow said "let's build the actual operating system for AI developers." That's the play.
