Dave Plummer built Windows' original Task Manager. Now he has vibe coded a version that runs on macOS and Linux too.
Plummer wrote the first Task Manager at Microsoft roughly three decades ago, and it has stayed a Windows-only fixture ever since, the tool millions of people open to kill a frozen app or check CPU usage. His new build changes that, extending the utility to Apple's and Linux's operating systems for the first time. He made it using "vibe coding," the now-common practice of prompting an AI model to generate most of the code rather than writing it by hand. The result is a familiar Windows tool showing up on platforms it was never designed for.
The bigger story here is what it says about AI-assisted coding rather than about Task Manager itself. A single developer porting a 30-year-old Windows utility to two other operating systems, without a company or a release cycle behind him, is the kind of project that used to take a team. It is a small but concrete sign that vibe coding has moved past toy demos into recognizable, nameplate software.
Whether Mac and Linux users, who already have Activity Monitor and system monitors of their own, actually need a Task Manager clone is a separate question entirely.
