Legal Alternatives for Bandwidth Management

If you need to manage bandwidth on your own network:

  1. Router QoS (Quality of Service) – Most modern routers let you set bandwidth limits per device. This is legal, effective, and doesn’t require shady software.

  2. NetLimiter (Windows) – Controls how much bandwidth your own PC uses. Does not attack others.

  3. SoftPerfect WiFi Guard – Scans for unknown devices but does not block them. Useful for security, not sabotage.

  4. Talk to the network admin – If someone is hogging bandwidth in a shared home or office, ask them to limit streaming/gaming during peak hours or upgrade the plan.

Option 1: GitHub Open-Source Alternatives (Recommended)

While the original V2 is not on GitHub, the most trusted repository for this type of utility is NetCut or BetterCAP. However, for the exact legacy tool, look for archived repositories from reputable cybersecurity researchers.
