05 · Why Kaku<br>A terminal should let you start working first.

I live in the terminal. I used Alacritty for years for its speed, then wanted stronger tabs and panes as my work shifted toward AI coding. Kaku builds on a fast, proven engine, adds practical defaults and shell tools, and puts an assistant within reach, all in one fast, quiet macOS app.

06 · Questions<br>Common questions

How do I install Kaku?<br>Download the DMG from GitHub Releases, or use the Homebrew tap: brew install tw93/tap/kakuku. An unrelated kaku package exists, so the tap avoids the wrong one.<br>How is Kaku different from iTerm2?<br>iTerm2 is a mature macOS terminal. Kaku is a lighter, faster alternative with practical defaults, fast tabs and panes, a curated shell suite, and an AI assistant, ready out of the box.<br>How is Kaku different from Warp?<br>Warp is closed source and built around a cloud account. Kaku is MIT open source, requires no account, and AI requests only go to the Provider you configure.<br>Is Kaku paid?<br>No, Kaku is an MIT-licensed open source project.<br>Does Kaku run on Windows or Linux?<br>Not yet, the current focus is getting the native macOS experience solid first.
