CyberManager is a lightweight, high-capacity virtualized task manager. Powered by the native NT engine, it offers instant search and a compact mode. The ultimate alternative to Windows Task Manager.
Free and open source (GPLv3) — no ads, no tracking, and no data collection. Just enjoy it.
Most task managers either freeze under heavy load or bury basic features behind complex UIs. CyberManager gives you instant process control, real-time telemetry, and deep system insights — all in a frameless, neon-styled interface that stays responsive no matter how many processes you run.

Windows may show a SmartScreen warning the first time you run the CyberManager installer — this is an unsigned hobby app, so Windows hasn't built reputation for the file yet. This is expected; the source is public so you can inspect exactly what it does. The same can appear when launching the portable build.

I’ve spent countless hours building and refining CyberManager for my own use. I recently decided to share it with the world as part of the CyberGems set of free and open-source tools.
If you’d like to support future updates, I’d truly appreciate it. You can also show your support by starring the repo on GitHub. Thank you! 🙏
