Thanks for checking out BroadcastDetector!

I built this tool after struggling with hard-to-diagnose issues in enterprise and SMB networks – especially broadcast storms and switch loops that silently bring everything down. Most tools focus on Layer 3 and above, while this one keeps an eye on the chaos at Layer 2.

It’s fully passive (no active probing), uses `tcpdump` + `pyshark` under the hood, and stores all detection logs locally in CSV (MAC, VLAN, timestamps, etc). It runs well on low-power devices like Raspberry Pi 4/5, which makes it ideal for plugging directly into a trunk port and letting it monitor multiple VLANs.

If you’ve ever had to troubleshoot sudden ARP storms or mystery broadcast floods, I’d love to hear how you handled them – or what tooling you use. Feedback on performance, packet handling, or edge case behavior is super welcome.

Would also love suggestions if anyone’s worked on similar tools or has ideas for improving broadcast visibility in a lightweight way.

Thanks again!
