Netra

Netra is a self-hosted network traffic observability tool that runs as a single binary, using eBPF to capture and analyze traffic from a mirrored network port without sitting inline on production traffic. It provides real-time dashboards of protocol and top-talker traffic, heuristic scan and DDoS detection, GeoIP enrichment, and an AI assistant that can answer questions over the collected traffic history. It's aimed at network and infrastructure engineers who want visibility without deploying a heavier commercial platform.
