Themes

Cruncher ships with four built-in dark colour themes. The active theme is stored in your config file and applied across the entire UI — the editor, log rows, charts, and syntax highlighting all react automatically.

Setting the Theme

Add (or update) the ui.theme key in ~/.config/cruncher/cruncher.config.yaml:

ui:
  theme: nord

You can also change the theme at runtime from Settings → General without editing the file manually — the selection is written back to the config file immediately.

Restart is not required; the change takes effect as soon as you save via the UI.

Available Themes
