ttl

ttl is a fast, modern network diagnostic and traceroute tool written in Rust featuring a real-time terminal user interface (TUI).
It functions as an advanced alternative to traceroute and mtr, offering per-hop statistics, ASN/GeoIP lookups, and ECMP path detection.
It also supports multi-target tracing, path MTU discovery, NAT detection, and route flap alerts with sparkline visual themes.
In addition to the interactive TUI, it can output scriptable data (JSON, CSV) or run in a headless daemon mode with a Prometheus exporter.
