What is it?

Ghostty Config is a browser-based tool for editing Ghostty terminal settings without hand-writing the config file. You adjust fonts, colors, cursor styles, transparency and other options through categorized pages, and the tool previews the effect in real time before exporting a ready-to-use config.

Settings are generated from a typed schema based on Ghostty's own config specification. Only values that differ from Ghostty's defaults are written to the output, which keeps the exported file short. Each setting includes inline help, platform badges (macOS, Linux, GTK) and minimum Ghostty version indicators.

The app is built with Svelte, TypeScript and Bun, and includes a built-in theme library, a font playground, a keybinding builder, and import/export with shareable URLs. The hosted version is deployed on Cloudflare Workers, and the static build can be run locally or self-hosted.

Key features

  • 01Visual editor for categorized Ghostty settings with inline documentation.
  • 02Built-in library of Ghostty color themes with live preview.
  • 03Real-time interactive terminal preview that re-themes as you edit.
  • 04Keybinding builder with trigger and action validation.
  • 05Import, export and shareable URLs, outputting only non-default settings.
  • 06Platform and minimum version badges for each setting.

Use cases

  • Setting up a new Ghostty terminal without memorizing config syntax.

  • Sharing a terminal configuration with teammates via a link.
