Appreciate it! Calyx has more than just the looks though. Tab groups, session persistence, command palette, git sidebar. Might be worth a try. https://github.com/yuuichieguchi/Calyx

The README has the full feature list. The tagline is just a one-liner. https://github.com/yuuichieguchi/Calyx

Good question! The OS handles Liquid Glass automatically for standard UI elements (title bars, sidebars, toolbars). I use .glassEffect() on those parts. But the terminal content area is a custom Metal-rendered surface from ghostty, so the OS can't automatically apply glass to it.

On the accessibility point, if you disable transparency effects, the glass parts will respect that. But Calyx won't just become Ghostty. The features beyond glass (tab groups, command palette, session persistence, notifications, browser tabs, git viewer, etc.) are all still there. Glass is the visual layer, not the core of what Calyx adds.

Hi, thanks for the feedback! To clarify, I do use the built-in .glassEffect() modifier on SwiftUI components (sidebar, tab bar, command palette, browser toolbar). The terminal surface itself is the hard part. It's backed by ghostty's Metal renderer which draws its own opaque background, so simply slapping .glassEffect() on it doesn't work. I've been working on improving transparency there but it's not as simple as a few lines of code when you're wrapping a GPU-rendered terminal engine. The titlebar is intentional for now, but I'm considering options there.

None of the UI elements in the screenshot follow apple liquid glass styles / guidelines afaict, whether or not glassEffect() is being used.

Fair point. I'll review the guidelines more carefully and update the styling. Thanks for pushing on this.

Hi, thanks for the feedback. I've added a screenshot to the README. Hope you like it.

To be fair: no, I dislike it. It looks completely unreadable. I still don't know why Apple thinks this is a good idea.

This is not what Liquid Glass actually looks like on first-party macOS applications. This needs way more blur and opacity to match even the control center widgets.

I've updated the glass styling since then. Would appreciate it if you could take another look. https://github.com/yuuichieguchi/Calyx

Apple isn't suggesting to adopt this for your terminal, given they haven't made the native terminal glassy.

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.

Do you have a screenshot!? I'll happily move to Calyx if it looks to my taste.

Hi, I've added a screenshot to the README. Thanks for the nudge!

Did you have trouble using tmux to organize your terminal sessions?

Hi, thank you for asking. Honestly, I didn't know about tmux when I started this project. I was only familiar with Ghostty and cmux, and I really wanted a translucent terminal with Liquid Glass. Plus, building my own means I can customize it however I want going forward. So I just went for it.

Also, tmux is really a different approach. Sometimes people just want to manage it on their workstation instead of on the server side.

Thanks! If you try it out, feel free to open issues or share feedback on GitHub.

v0.7.2 released: Basic Auth for self-hosted ntfy servers

Nice — different use case but same underlying problem. ntfy is the right call when you're away from the machine. Voxlert handles it when you're nearby but in another window: each Claude Code session gets a distinct character voice (SHODAN, StarCraft Adjutant, GLaDOS) so you hear which session needs attention without alt-tabbing.

The two actually pair well — ntfy for remote approval, Voxlert for ambient desk awareness.
