Ghostty
Terminal emulator built in Zig with platform-native UI and GPU acceleration. 2ms key-to-screen latency. Metal on macOS, Vulkan/OpenGL on Linux. By the co-founder of HashiCorp.
Ghostty is a terminal emulator built from scratch in Zig by Mitchell Hashimoto (co-founder of HashiCorp). It uses a custom GPU rendering pipeline targeting Metal on macOS and OpenGL 3.3/Vulkan on Linux, delivering 2ms key-to-screen latency at the threshold of human perception. The macOS app is a true SwiftUI application with real windowing, menu bars, and a settings GUI rather than a web-wrapped Electron shell. It outperforms every competitor in raw rendering benchmarks while looking and feeling completely native on each platform. There are no AI features built in, which is the point: Ghostty is for developers who want the fastest, most reliable terminal possible and run their AI tools (Claude Code, Codex CLI, etc.) inside it. For anyone frustrated with Electron-based terminals, Ghostty is the performance ceiling.
