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?

[yuu1ch13]

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.
