tw93/Kaku: Fast Rust Terminal Built From the Ground Up for AI Coding — macOS-First, 3K Stars
GitHub·medium signal
Kaku is a macOS terminal written in Rust with AI coding workflows as the first-class design constraint, not a plugin bolted onto an existing shell. At 3K stars it occupies the same performance tier as Zed — minimal overhead when multiple agents are running — but focused on the terminal layer rather than an editor. The out-of-the-box AI coding positioning targets developers who want the coding agent environment to be as fast as the agents themselves.
