Description

proc-janitor is a daemon that scans for orphaned processes (those with PPID=1) that continue running after their parent terminal or application exits, and cleans them up automatically. It supports configurable scanning intervals, target and whitelist patterns, and safe termination with grace periods. The tool helps prevent memory waste from zombie processes like Node.js or MCP servers, improving system performance and user convenience.
