Show HN: Calyx – Ghostty-Based macOS Terminal with Liquid Glass UI

It's only a few lines of code to use the built-in liquid glass.

As far as I can tell, this doesn't use it.

Also, for the vibe that this is going for, very surprised the title bar was left in.

Code has lots of claims that something is done and it isn't.

Hi everyone, I'm the developer of Calyx.

I was a Ghostty user but kept running into the same problem: too many tabs, no way to organize them. Ghostty doesn't have tab groups or a plugin system, so I built Calyx using libghostty as the rendering engine.

The idea is simple — keep Ghostty's speed, but add the workflow features I was missing:

  - Tab Groups — color-coded, collapsible groups to organize tabs by project

  - Command Palette (Cmd+Shift+P) — search and run any action

  - Session Persistence — tabs, splits, and working directories survive restarts

  - Notification Badges — OSC 9/99/777 notifications with per-tab badge counts

  - Built-in Browser — open docs right next to your terminal

  - Terminal Search (Cmd+F) — find text in terminal output

  - Git Diff View — inline source control diffs

  - IPC MCP Server — programmatic control from tools like Claude Code (Demo: https://youtu.be/LHY-NJEqBTg)

  - Scrollbar, cursor-click-to-move, Liquid Glass UI throughout

You should post a screenshot in the README to give people an idea of what the terminal looks like.

Sorry, not my cup of tea. I think UI peaked with minimal/material/flat a few years ago, which also made me more calm.

Besides that, I think readability could be an issue.

Forgive me if I got it wrong but isn’t the chrome supposed to be taken care by the OS (Liguid Glass in this case) and Ghostty to just behave as Ghostty?

If I use Calyx but I have set up macOS to be non liquid glassy as much as possible with Accessibility features, etc. will Calyx just be GHostty?

It would be hard to convince me to move away from iterm2. But a theme for it would get massive adoption.

Is this a joke
