You already know Activity Monitor
isn't built for this.

Activity Monitor

System diagnostic tool

  • × Open Spotlight → search → wait for load → find process → confirm kill → done. 30 seconds.
  • × Process names don't match app names. Which "python3" is yours?
  • × No memory. You hunt the same zombie processes every single day.
  • × Kill one at a time. 47 Chrome helpers? Good luck.
  • × No auto-monitoring. You're the monitor.

PIDKill

Precision process killer

  • ✓ Open PIDKill. See targets. One click kills. 2 seconds.
  • ✓ Fuzzy search matches executable names, localized names, and paths.
  • ✓ Set your targets once. PIDKill remembers and auto-scans.
  • ✓ Kill all matching processes at once. Batch operations.
  • ✓ Continuous monitoring. Scan every 3–60 seconds, configurable.
  • ✓ Inspect: real-time disk & network I/O ranking. Record and replay sessions.
Real scenarios

Sound familiar?

iOS Developer
Xcode Residuals

Xcode crashed, but CoreSimulatorService and a few related processes are still eating memory. Opening Activity Monitor, searching, killing them one by one — tedious.

PIDKill: Add "Simulator" to targets. One click clears all residuals. SYS/3RD labels prevent accidental kills.
Full-Stack Engineer
Chrome Memory Hogs

Fans spinning. Dozens of Chrome Helper processes in Activity Monitor. Force-quit Chrome loses all your tabs. But which helpers are safe to kill?

PIDKill: Browse all Chrome helpers sorted by memory. Kill the heavy ones, keep your tabs alive.
Backend / DevOps
Docker Ghost Processes

docker-compose down finished, but port 8080 is still in use. A node process didn't exit cleanly. Maybe a redis-server too. Happens more often than you'd like.

PIDKill: Add docker, node, redis to scan list. See all residuals in one view, clear with one click.
UI/UX Designer
Adobe Background Daemons

You quit Photoshop but Adobe daemons keep running — CCXProcess, AdobeIPCBroker, CoreSync. Kill one in Activity Monitor, another respawns it.

PIDKill: Monitor all Adobe processes. Auto-scan kills them as they respawn. They stay dead.
Power User
Respawning Processes

Some processes restart seconds after you kill them. Creative Cloud, update agents, sync daemons — they have watchdogs that bring them right back.

PIDKill: Auto-scan every 3–60 seconds. Process respawns? PIDKill kills it again. Automatically. Persistently.
Features

Everything you need.
Nothing you don't.

Fuzzy Matching

Match by executable name, localized display name, or path. Find "AirDrop" by typing its Japanese name. No more guessing.

◉

Inspect: I/O Monitor

Real-time disk & network I/O ranking by process. Record sessions and replay them to trace what happened. Find the process thrashing your SSD.
