TUIs

Keystone Terminal includes several terminal user interfaces as part of the default workflow.

Core TUIs

  • Helix for editing
  • Zellij for multiplexing and session layout
  • Lazygit for Git workflows
  • Yazi for file management

Productivity and personal workflow TUIs

Depending on enabled modules, Keystone also includes:

  • Himalaya for email
  • Calendula for calendars
  • Cardamum for contacts
  • cfait for tasks
  • Comodoro for timers

Why Keystone uses TUIs

The Keystone terminal environment is designed to stay keyboard-first and to work consistently across NixOS, macOS, and other Linux systems.

TUIs are a good fit because they:

  • work locally and remotely,
  • compose well inside Ghostty and Zellij, and
  • preserve a similar workflow across graphical and headless machines.
