Harness

GPU-rendered native macOS terminal that keeps agent sessions running and alerts you when one needs input.

Desktopfreeglobal

Harness is a native macOS terminal, GPU-rendered for performance, built specifically for running AI coding agent sessions. It keeps sessions alive and alerts the user the moment an agent needs input, rather than requiring the user to keep checking back. It's aimed at developers who run AI coding agents in the terminal and want to know immediately when one is waiting on them.
