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.
