Kaku
Fast, zero-config terminal built for AI coding workflows
Overview
Kaku is a macOS terminal emulator built specifically for AI-assisted coding workflows. A customized fork of WezTerm written in Rust, it ships ready to use with JetBrains Mono font, an optimized color theme, Starship prompt, z directory jumper, Delta syntax highlighter, zsh completions, and autosuggestions — all preconfigured out of the box. Kaku delivers a 40% smaller binary than WezTerm (~40MB vs ~67MB) with instant startup and optimized shell bootstrap times around 100ms. It maintains full WezTerm Lua API compatibility, so existing configurations carry over. Designed as the ideal terminal companion for AI coding tools like Claude Code, Codex CLI, and other CLI-based agents, Kaku provides a fast, polished environment that stays out of your way while you work.
