Ghostty is a modern, open-source terminal emulator created by Mitchell Hashimoto (co-founder of HashiCorp, creator of Terraform and Vagrant). Released as open-source in December 2024, it became one of the most-discussed developer tools on Hacker News and GitHub within months of launch, reaching ~50K GitHub stars by early 2026.
Key Features
Native Metal Rendering (macOS) – The only terminal emulator that uses Apple's Metal framework directly, rather than routing through the deprecated OpenGL compatibility layer. This gives Ghostty native ProMotion (120Hz) support, adaptive sync, and power-efficient rendering on Apple Silicon.
Native macOS UI – Uses AppKit and SwiftUI for its UI, meaning native tabs, native fullscreen, and native font rendering. It feels like a Mac app — not a cross-platform wrapper.
Quick Terminal – A global hotkey drops a Quake-style terminal over any application, similar to iTerm2's hotkey window.
Simple Key-Value Config – Plain text configuration (no YAML, no TOML, no JSON — just key = value pairs) that is easy to read and version-control.
Zero Telemetry – No accounts, no tracking, no cloud. As of December 2025, Ghostty moved under Hack Club's 501(c)(3) as fiscal sponsor, deliberately contrasting its model with VC-backed terminals.
Fast Scrollback – Supports up to 25 million lines of scrollback, a key requirement for long-running AI agent sessions.
Why Use Ghostty?
Ghostty is the terminal for developers who want the absolute best native macOS experience without compromise. If you care about frame rate, input latency, Apple Silicon efficiency, and privacy — and you don't need a GUI preferences pane or Windows support — Ghostty is the strongest choice in 2026.

Curated highlights from Reddit and other communities, not user-submitted reviews.
“Developers praise Ghostty's zero-config onboarding and platform-native UI, noting that it runs out of the box in under 5 minutes with thoughtful defaults, completely bypassing the heavy configuration required by other modern terminals.”
Medium: Why Everyone's Talking About Ghostty
“Its GPU-accelerated performance is highly regarded—especially its efficient rendering on macOS Retina displays and its minimal resource footprint compared to Electron-based alternatives.”
Hacker News: Ghostty 1.0
“Ghostty's move to a 501(c)(3) non-profit fiscal sponsorship under Hack Club has strongly resonated with the community, ensuring long-term stability and mission-driven development free from VC pressures or mandatory telemetry.”
“Ghostty officially supports only macOS and Linux, with no Windows version available, which remains a dealbreaker for developers requiring a unified cross-platform terminal experience.”
Sesame Disk: Ghostty Terminal Review: Emulator Features and Performance
“There is no GUI settings manager; all customization must be done via a file-based configuration. Power users migrating from iTerm2 miss the visual profile management and point-and-click interface.”
“While performance is generally excellent, users have reported edge-case bugs with font rendering for non-Latin scripts (such as Arabic) and occasional crashes when displaying very large continuous text streams.”
