GoKawiilTask Manager creator Dave Plummer launches cross-platform TMOG using AI-assisted coding
Dave Plummer, who originally wrote Windows Task Manager, has released TMOG, a system and process monitoring tool for macOS, Linux and Windows. He built it in under six weeks with two collaborators using Claude Code to accelerate development, and it's sold outside the App Store due to Apple's sandboxing restrictions on process management. A free version is available indefinitely, while a $39.95 Pro tier adds a record-and-replay feature called Flight Recorder for diagnosing past slowdowns.
The project is a real-world test of how much AI coding assistants can compress the time and team size needed to ship a native cross-platform utility, something that traditionally required dedicated engineers per OS or a compromise like Electron wrapping. Coming from someone who once hand-optimized Task Manager to 80KB, the endorsement carries unusual credibility about AI tools' current capabilities and limits for serious system-level software.
- TMOG monitors processes on macOS, Windows and Linux, with a paid Pro tier adding a replay-based slowdown diagnostic tool.
- Plummer built it in six weeks with two collaborators by relying heavily on Claude Code and a detailed 107-page spec.
- It's sold via Lemon Squeezy rather than Apple's App Store because sandboxing rules block apps from listing or killing system processes.
