v0.1.0 — Initial release

A small, native macOS (SwiftUI) app that puts a UI on top of your Ghostty config file — that's really all it is. It reads your actual ~/.config/ghostty/config.ghostty and drives your installed ghostty CLI (+show-config, +list-themes, +validate-config), so it doesn't reimplement anything or keep its own options list that could drift out of date.

What you can do with it:

• Browse every option with its official docs, default, and your current value.
• Edit safely — each change is checked with ghostty +validate-config before it touches your file.
• Search options by intent, preview and apply themes, and rebind keybindings.
• Optionally have Ghostty reload the moment you save.

Install: download the zip below, unzip it, and drag Ghostty Config Editor.app into /Applications.

Note

First launch: this build is ad-hoc signed and not notarized, so macOS Gatekeeper blocks it once with "Apple could not verify … is free of malware." This is expected — clear it either way (just once; macOS remembers afterward):

• System Settings: open the app, click Done on the warning, then go to System Settings → Privacy & Security, scroll to Security, and click Open Anyway next to the app's name. On macOS 15 (Sequoia) / 26 (Tahoe) this is the reliable route — the older right-click → Open trick no longer works dependably.
• Terminal (fastest): xattr -dr com.apple.quarantine "/Applications/GhosttyConfigEditor.app", then double-click.

Built and tested against Ghostty 1.3.1 — the full list is in the CHANGELOG.

It's an unofficial, community tool, not affiliated with the Ghostty project. If it's useful to you, a star helps other people find it — and issues and PRs are welcome.
