ttl is a fast, modern traceroute and network diagnostic tool written in Rust with a real-time TUI, per-hop latency/loss/jitter statistics, and ASN/GeoIP/reverse-DNS enrichment. It extends classic traceroute/mtr with ECMP path enumeration, path MTU discovery, NAT detection, MPLS label parsing, and a Prometheus-exporting daemon mode.

Use cases

• trace network paths with per-hop latency and packet loss stats
• diagnose why my connection is slow or dropping packets
• detect ECMP load balancing and enumerate parallel routes
• find the path MTU between two hosts
• look up which ASNs and IXs my traffic traverses
• continuously monitor route stability with alerts on path changes
• export traceroute metrics to Prometheus

When to choose

• you want a modern, faster alternative to mtr with a rich TUI
• you need ECMP detection, MTU discovery, or NAT detection in one tool
• you want scriptable JSON/CSV output or headless Prometheus monitoring
• you need ASN, GeoIP, and PeeringDB IX enrichment during traces

When to avoid

• you only need a one-shot simple traceroute with no stats
• you need a GUI-based network diagnostic tool
• you cannot grant raw socket / setcap privileges on the host
