# Alacritty vs Kitty Published January 1, 2026 ยท Updated August 10, 2026 Kitty is the top pick for most Mac users looking at terminals. It is free and open-source and installs in one Homebrew command. Alacritty is the stronger choice if you want terminal. As of October 2026, both install with brew install --cask alacritty and brew install --cask kitty. For most Mac users in 2026, Kitty is the better choice for terminals because it is a free, install-in-one-command replacement for Warp. Both install with a single Homebrew command, so the switching cost is low. Choose Alacritty instead if you want terminal. ## Head to head | Factor | Alacritty | Kitty | | --- | --- | --- | | Price | Free | Free | | Open Source | Yes | Yes | | Replaces | โ€” | Warp ($20/month) | | Best for | terminal, gpu, fast | terminal, gpu, fast | | Install | brew install --cask alacritty | brew install --cask kitty | | Category | Developer Tools | Developer Tools | ## Alacritty GPU-accelerated terminal emulator Install: `brew install --cask alacritty` [Alacritty on Bundl](https://bundl.run/apps/alacritty) ## Kitty GPU-based terminal emulator Install: `brew install --cask kitty` [Kitty on Bundl](https://bundl.run/apps/kitty) ## Features - **Window Management.** Kitty and Ghostty both win integrated window management over Alacritty; Kitty goes deeper on layouts and remote control. - **Graphics and Media.** Kitty leads the protocol; Ghostty is compatible enough for many image workflows; Alacritty stays text-first. - **Configuration.** Tie on preference: Alacritty for short TOML files, Kitty for scriptable depth. - **Performance & Latency.** Both are GPU-fast; pick on features, not microbenchmarks. - **Font Support & Ligatures.** Kitty wins for typography that needs ligatures and advanced font shaping. - **Extensibility (Plugins).** Kitty's kitten framework wins when you want first-party extension points. - **Remote Connectivity.** Kitty's SSH kitten is the better fit for frequent remote work. - **Cross-Platform Support.** Alacritty wins on reach thanks to native Windows support. - **Native macOS feel (tabs, Metal, system chrome).** Among Alacritty and Kitty, Kitty feels denser on Mac; Ghostty is often preferred when pure native chrome is the priority (see three-way section). - **Multiplexer independence.** If 'Alacritty or Kitty' hinges on whether you want another config language for panes, Kitty removes that requirement for local work. ## FAQ ### Alacritty or Kitty: which should I install on a Mac? Install Kitty if you want native tabs, splits, images, ligatures, and remote control without learning tmux first. Install Alacritty if you already use tmux or Zellij and want the lightest GPU window with short TOML. Most single-Mac developers land on Kitty. ### Alacritty vs Kitty vs Ghostty: who wins? There is no universal winner. Kitty wins feature depth (kittens, sessions, remote control). Ghostty wins native macOS UI feel with Metal/AppKit chrome while still supporting the Kitty graphics protocol. Alacritty wins minimalism and native Windows support. Pick the constraint you refuse to compromise: panes without tmux (Kitty/Ghostty), smallest surface (Alacritty), or Windows fleet sameness (Alacritty). ### What versions are current in August 2026? Alacritty advertises 0.17.0 downloads on alacritty.org. Kitty's changelog lists 0.48.2 on 2026-07-30 as a current patch in the 0.48 line. Ghostty ships continuous open-source releases from ghostty.org; check the download page for the build you install. ### Which is faster? All three are GPU-accelerated and fast enough that interactive latency is rarely the decider. Choose features, native UI preferences, and platform support instead of chasing benchmark screenshots. On M-series Macs Alacritty, Kitty, and Ghostty all feel immediate for shell work. ### Does Alacritty have tabs? No native tabs or splits. Use tmux, Zellij, or separate OS windows. That is intentional design, not a missing bug-fix item. Kitty and Ghostty both provide native tabs and splits. ### Can Kitty show images? Does Ghostty? Yes for Kitty: graphics protocol and icat kitten display images in the terminal. Ghostty supports the Kitty graphics protocol so many image-capable TUI tools work there too. Alacritty does not centre on an image protocol. ### Which is better with Neovim? All three work. Kitty's keyboard protocol, image support, and multi-pane layouts appeal to many Neovim users. Ghostty is popular when font rendering and native tabs matter. Alacritty users often pair with tmux and stay happy. ### Is Kitty stable on macOS Tahoe? Recent Kitty changelogs explicitly mention Tahoe-related fixes and workarounds. Keep Kitty updated after OS point releases. Ghostty's native AppKit path is also aimed at current macOS behaviour. ### How do I configure each? Alacritty uses ~/.config/alacritty/alacritty.toml. Kitty uses kitty.conf with optional includes and kitten UIs for some tasks like font selection. Ghostty uses a simple configuration file focused on readable keys rather than a plugin runtime. ### Which should beginners install? If you want fewer decisions on a Mac, Kitty or Ghostty are friendlier than Alacritty because tabs and splits work without a multiplexer. If a mentor already standardised on tmux plus Alacritty, follow that stack for consistency. ### Are they free for commercial use? All three are open source. Review Apache 2.0 (Alacritty), GPL-3.0 (Kitty), and MIT (Ghostty) obligations if you redistribute modified binaries. ### What about iTerm2? iTerm2 remains a popular macOS-native alternative with profiles and its own experiments. This page compares Alacritty and Kitty as GPU-first open terminals and places Ghostty in the three-way because search demand groups those three together. ### Alacritty or Kitty for a beginner on Mac? Kitty (or Ghostty). Beginners who install Alacritty without a multiplexer often bounce because there are no tabs. If a team mentor already standardised on Alacritty plus tmux, follow that stack so configs match. ### What are the dealbreakers? Alacritty dealbreakers: you need ligatures, inline images, or tabs without tmux. Kitty dealbreakers: you need a native Windows terminal, or you refuse GPL-3.0 for redistribution. Ghostty dealbreakers in the three-way: you need Windows-native parity or the full kitten remote-control surface. ### How much migration effort should I plan? Font and colour ports are usually under an hour either direction. Pane muscle memory is the real cost: leaving Kitty tabs for Alacritty means learning tmux or Zellij; leaving Alacritty for Kitty means unlearning a few tmux chords if you drop the multiplexer for local work. Keep both apps installed during a one-week bake-off. ### Is Kitty faster than Alacritty in 2026? Not in a way that should decide your install. Both are GPU-accelerated. Alacritty is tuned for a smaller feature surface; Kitty stays competitive while carrying more UI state. Measure paste of large logs and Neovim redraw on your own M-series Mac instead of trusting social media FPS clips. ### Does GPL-3.0 on Kitty matter for me? For personal use, almost never. It matters if you ship a modified Kitty binary inside a proprietary product. Alacritty (Apache 2.0) and Ghostty (MIT) are more permissive for redistribution scenarios. Read the licences if that is your job; otherwise pick on features. ## Sources - [Alacritty official site](https://alacritty.org/) - [Alacritty GitHub releases](https://github.com/alacritty/alacritty/releases) - [Kitty terminal home](https://sw.kovidgoyal.net/kitty/) - [Kitty changelog](https://sw.kovidgoyal.net/kitty/changelog/) - [Kitty GitHub repository](https://github.com/kovidgoyal/kitty) - [Alacritty GitHub repository](https://github.com/alacritty/alacritty) - [Ghostty official site](https://ghostty.org/) - [About Ghostty](https://ghostty.org/docs/about) - [Introducing Ghostty (Mitchell Hashimoto)](https://mitchellh.com/writing/ghostty-and-useful-zig-patterns) - [Terminal Trove comparison table (2026)](https://terminaltrove.com/compare/terminals/) ## Related - [Ghostty vs Alacritty](https://bundl.run/compare/ghostty-vs-alacritty) - [Warp vs Alacritty](https://bundl.run/compare/warp-vs-alacritty) - [Alacritty vs WezTerm](https://bundl.run/compare/alacritty-vs-wezterm) - [WezTerm vs Kitty](https://bundl.run/compare/wezterm-vs-kitty) - [Ghostty vs Kitty](https://bundl.run/compare/ghostty-vs-kitty) ```json { "@context": "https://schema.org", "@graph": [ { "@type": "Organization", "@id": "https://bundl.run/#organization", "name": "Bundl.run", "url": "https://bundl.run", "logo": { "@type": "ImageObject", "url": "https://bundl.run/og-image.png", "width": 1200, "height": 630 }, "description": "The Ninite for Mac.
