Fast, modern traceroute with real-time TUI, per-hop stats
...It uses a full-screen terminal UI to continuously probe paths and refresh hop-by-hop measurements, which makes transient loss, jitter, and routing changes much easier to spot. The design emphasizes per-hop visibility with live statistics, and it enriches what you see by resolving network identity details like ASN and geolocation when available. It is also built for messy real-world routing, including multipath behavior, so it can probe with multiple flows and surface ECMP patterns instead of pretending there is only one stable route. For deeper path analysis, it can parse MPLS label information when present, helping you understand what a provider network is doing beyond plain IP hops.
