What it is

Ghostty is a cross-platform terminal emulator built on GPU acceleration and native platform UIs (Cocoa on macOS, GTK/Win32 elsewhere) that prioritizes speed, features, and native look-and-feel simultaneously. The core engine is libghostty—a C/Zig library providing standards-compliant terminal emulation (VT100+ control sequences) that can be embedded into other applications or wrapped by native UI frontends. Monorepo structure: pkg/ contains reusable packages (fontconfig, freetype, breakpad, apple-sdk, android-ndk, dcimgui) with Zig build manifests (build.zig/build.zig.zon); core terminal emulation is likely in main source tree (not visible in file list excerpt). Platform-native…

Start here

Open these first:

  • pkg/README.md — Overview of all pkg/ dependencies and their integration into the Ghostty build system.
  • pkg/fontconfig/build.zig — Core fontconfig Zig binding build configuration; essential for font system initialization.
  • pkg/freetype/build.zig — FreeType2 binding build configuration; critical for glyph rendering pipeline.
  • pkg/harfbuzz/build.zig — HarfBuzz text shaping build configuration; required for complex text layout and rendering.
  • pkg/glslang/build.zig — GPU shader compilation build setup; essential for GPU acceleration features.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repository: git clone https://github.com/ghostty-org/ghostty.git && cd ghostty. Check HACKING.md (referenced in README for development setup) for build instructions. Based on build.zig and build.zig.zon…

Daily commands:

No package.json, Makefile, or clear dev-server pattern evident. Inferred from build.zig structure: zig build (or zig build --help to list targets). Platform-specific: zig build macos / zig build linux / `z…

Key cautions & unknowns

  • Concentrated ownership — top contributor handles 68% of recent commits
  • Polyglot build system: Zig build orchestrates C, C++, Swift, Metal, and GLSL—missing SDK paths (apple-sdk, android-ndk) will silently fail. Platform coupling: Swift code (macOS) and likely Win32 (Windows) are…
  • Published-advisory coverage was unavailable for the captured dependencies.
  • Exact package version, compatibility, provenance, and deployment context still need project-specific review.
