Baa

Baa is a menu bar utility for macOS that monitors memory and disk usage, detects idle processes, and frees system resources.

Baa is a menu bar utility for macOS that monitors system RAM and disk space, warning users before resources run out. It identifies leftover applications, zombie scripts, forgotten AI agent sessions, and idle development tools such as Docker and Ollama models. The software displays free RAM in the menu bar and changes color based on memory pressure. Users can review identified items, see how much memory each consumes, and clear them with a single click. It also detects and cleans up development junk filling up the disk, such as old builds and package caches.
