Kaku is a deeply customized fork of WezTerm, designed for an out-of-the-box experience.

• Zero Config: Polished defaults with JetBrains Mono, opencode theme, optimized macOS font rendering, smooth animations.
• Built-in Shell Suite: Comes pre-loaded with Starship, z, Delta, syntax highlighting, autosuggestions, and autocompletions.
• Fast & Lightweight: 40% smaller binary, instant startup, lazy loading, stripped-down GPU-accelerated core.
• Lua Scripting: Retains the full power of WezTerm's Lua engine for infinite customization.

1. Download Kaku DMG & Drag to Applications
2. Or install with Homebrew: brew install tw93/tap/kakuku
3. Open Kaku. The app is notarized by Apple, so it opens without security warnings
4. On first launch, Kaku will automatically set up your shell environment

Kaku comes with intuitive macOS-native shortcuts:

Kaku comes with a carefully curated suite of CLI tools, pre-configured for immediate productivity:

• Starship: A fast, customizable prompt showing git status, package versions, and execution time.
• z: A smarter cd command that learns your most used directories for instant navigation.
• Delta: A syntax-highlighting pager for git, diff, and grep output.
• zsh-completions: Extended command and subcommand completion definitions.
• Syntax Highlighting: Real-time command validation and coloring.
• Autosuggestions: Intelligent, history-based completions similar to Fish shell.

Kaku uses ~/.config/kaku/kaku.lua for configuration, fully compatible with WezTerm's Lua API, with built-in defaults at Kaku.app/Contents/Resources/kaku.lua as fallback.

Run kaku in your terminal to see all available commands such as kaku update, kaku reset, and kaku config.

I heavily rely on the CLI for both work and personal projects. Tools I've built, like Mole and Pake, reflect this.

I used Alacritty for years, but its lack of multi-tab support became cumbersome for AI-assisted coding. Kitty has some aesthetic and positioning quirks I couldn't get past. Ghostty shows promise but font rendering needs work. Warp feels bloated and requires a login. iTerm2 is reliable but showing its age and harder to deeply customize.

WezTerm is robust and hackable, and I am grateful for its powerful engine. However, I wanted an environment that was ready immediately, without extensive configuration—and something significantly faster and lighter.

So I built Kaku to be that environment: fast, polished, and ready to work.

Achieved through aggressive stripping of unused features, lazy loading of color schemes, and shell optimizations.

1. Why is the Homebrew cask named kakuku instead of kaku?

   The name kaku conflicts with another package in Homebrew's official repository (an unmaintained music player). kakuku is a cute variation that's easy to remember.

2. Is there a Windows or Linux version?

   Not at the moment. Kaku is currently macOS-only while we focus on polishing the macOS experience. Windows and Linux versions may come later once the macOS version is mature.
