wtf is ghostty?

Ghostty is a terminal emulator, the program developers use to run text-based commands and tools. It aims to solve a common frustration: most terminals force you to pick between speed, useful features, or an interface that feels native to your operating system. Ghostty tries to deliver all three at once, so you get a snappy, polished app on both Mac and Linux. Under the hood, it achieves this speed through a multi-threaded design and GPU-accelerated rendering. Instead of just being a standalone app, the core terminal logic is also packaged as a library called libghostty. This means other developers can embed a full terminal directly into their own applications without building one from scratch. It supports modern terminal standards like image rendering, clipboard integration, and light/dark mode notifications. The primary users are developers who spend significant time in the command line and want a faster, more capable alternative to default options like Mac's Terminal.app or iTerm. A startup engineer juggling multiple terminal windows with splits and tabs, or a team building a custom code editor that needs a built-in terminal, would benefit directly. The project is already stable and reportedly used by millions daily. A notable tradeoff is the project's philosophy on "native" experiences. Rather than building a single, generic interface that looks the same everywhere, it builds distinct apps for each platform, SwiftUI on Mac, GTK on Linux. This means more work for the developers but a better experience for users. The project is also careful about creating custom features that only work in its own app, preferring to support existing standards to avoid fragmenting the terminal ecosystem.
