@eternityspring: As a Ghostty user, the most annoying thing: restarting the computer loses all terminals that have been open for days — each project has to be set up from scratch. After reading this article, I tried cmux and it completely solved the problem. cmux, like Ghostty, is based on the libghostty rendering engine: performance is identical, and it even reads Ghostty's existing themes and font configurations, making migration zero-cost.

As a Ghostty user, the most annoying thing is restarting the computer and losing all the terminals that have been open for days — each project has to be set up from scratch. After reading this article, I tried cmux and it completely solved this problem. cmux, like Ghostty, is based on the libghostty rendering engine: performance is identical, and it can even read Ghostty's existing theme and font configurations, making migration zero-cost. But it has a killer feature — full state restoration: Windows, workspaces, etc. can all be restored exactly as before. Even after restarting the computer, nothing is lost, and Claude Code sessions are automatically resumed. Plus a vertical workspace sidebar designed for AI agents: each project's git branch, PR status, listening ports, and latest notifications can be seen at a glance. Even with three or four agents running in parallel, it stays organized. macOS native with Swift/AppKit, not Electron, free and open-source (GPL). https://github.com/manaflow-ai/cmux
