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

yuu1ch13

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 Happy to answer any questions.

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.

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

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. https://developer.apple.com/documentation/SwiftUI/Applying-L... https://developer.apple.com/documentation/technologyoverview... 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.

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?

Ugh that screenshot. I really hate transparent terminals. I can live with slight transparency and a pretty low detail background but this would be so hard to read. This doesn't make me want to use it. I'm not on Mac anyway but still. I just use Konsole at the moment, sometimes kitty if I need something really low resource.

What is this obsession with transparent things?

A product tagline that: - name drops some technical thing, instead of saying what it does - mentions some other non feature Cool I guess?
