Most configurators generate a clean new file. Ghostty Studio opens the one you already maintain and changes only what you review.

• Preserves your document. Comments, ordering, includes, unknown keys, line endings, and blank lines stay where you put them.
• Makes every write visible. Preview the result and inspect the exact diff before anything reaches disk.
• Asks Ghostty, then leaves a way back. Ghostty validates the candidate and Studio creates a local restore point before saving.
• Stays on your Mac. No account, cloud service, telemetry, or remote image loading.

Current support

	Preview support

Read the exact version and configuration boundaries in the compatibility guide.

The journey

1. Open the real source. Studio discovers the standard macOS and XDG roots, follows supported includes, and explains when another source wins.
2. Adjust with context. Search reviewed settings or use the background studio for local PNG and JPEG images, fit, position, tiling, visibility, and switching.
3. Review the write. Nothing leaves the draft until you inspect its summary and exact diff.
4. Validate and save. Studio checks for outside edits, asks the installed Ghostty to validate, writes atomically, and keeps a private restore point.

Settings whose type, range, source behavior, or version contract is not yet proven remain searchable but read-only. Studio does not guess at write semantics.

Download

Download the latest preview for an Apple Silicon Mac running macOS 11 or later. The release page includes a SHA-256 checksum.

macOS may ask you to confirm the first launch because the preview is not notarized. Use the normal macOS security review flow; do not disable Gatekeeper. You can also build from source.

Run from source

You need Ghostty, Xcode Command Line Tools, Node 22.22.2, pnpm 10, and the pinned Rust toolchain.

pnpm install --frozen-lockfile
pnpm tauri dev

Run the complete frontend, website, and Rust checks with:

pnpm check

pnpm dev opens a read-only browser demo with sample data. pnpm package:macos-local creates an ad-hoc local package for development; it does not establish publisher identity.
