Leftovers is a native macOS menu-bar app and CLI that detects and cleans up memory leaks and disk clutter left behind by AI coding agents, dev servers, and MCP servers. It stands out by reading true process footprints (RAM + compressed + swap) and offering safe, rule-based cleanup with protections and a JSON CLI for agents.

Target audience: macOS developers and power users running local AI agents
