Show HN: Leftovers – find the processes your coding agents left running on macOS

Score: 7.5/10 (Innovation: 6, Technical: 8, Documentation: 9, Utility: 7)

Leftovers is a macOS menu-bar app that tracks down resource-hungry processes and forgotten background jobs left behind by coding agents, showing true memory footprint (RAM + compressed + swapped) rather than just resident memory. It also handles disk cleanup, git worktree pruning, and scheduled LaunchAgent management, with a CLI mode that agents themselves can call. The focus on agent-leftover cleanup is a timely niche, and the process-safety rules and threshold documentation are unusually thorough.

Target audience: macOS developers using coding agents, and devops engineers managing local dev environments
