Former Microsoft Dev Creates Cross-Platform Task Manager App TMOG

David Plummer, a former Microsoft developer, has created a new task manager app called TMOG (Task Manager OG) that works on macOS and Linux in addition to Windows. Plummer was responsible for developing the original Task Manager tool for Windows back in the 1990s.

TMOG is built using Claude Code, an AI-assisted development platform, which required Plummer to provide a 100+ page document detailing his requirements. The app uses Qt 6 on Linux, Swift/AppKit on macOS, and Direct2D on Windows, all sharing a common C++ core.

The task manager offers a real-time dashboard of system usage data, including per-process resource usage, power, CPU speed, and disk space. It also has a 'Flight Recorder' feature that enables users to rewind data to help identify issues when they occurred, rather than after the fact.

However, this feature, along with others such as a CPU benchmarking tool, is only accessible behind a $39.95 paid Pro tier. The app is currently in beta and available for download on Ubuntu, but users should expect bugs, especially considering it's free to use for live monitoring without the paid plan.
