HopCount

Terminal soul, mobile body.

HopCount is a focused network diagnostic app built for engineers, sysadmins, and developers who need reliable troubleshooting without distraction. Debug connectivity, trace paths, inspect SSL, analyze BGP, and monitor uptime with real answers. Distance-aware verdicts know distant links should read healthy, not degraded, and cancellable tests stop instantly with clean state. The interface is minimal. No ads, no popups, no accounts, no tracking. Just diagnostics and results. Built for network engineers who follow the packets, not assumptions.

How to use

Type a target and pick an op. Run diagnostics with latency, packet loss, jitter, and hop analysis, follow packets hop by hop, and inspect SSL certificates with full chain validation. Resolve DNS records and check propagation globally across multiple resolvers, query WHOIS, reverse DNS, MAC vendors, and IP reputation. Run advanced BGP routing analysis with live data, plus full offline analysis for path selection, policy testing, attribute decoding, and configuration help. Set continuous ICMP and HTTP monitoring with scrollable historical graphs, SLA tracking, anomaly detection, per-target thresholds, maintenance windows, and SSL expiry alerts, background-safe across reboots. Let playbooks run the right sequence for common scenarios, or get an instant health briefing for any target. Plan networks with the subnet, supernet, overlap, route summary, and VLSM calculators. Save, search, re-run, and share past sessions, and export your full configuration as an AES-256 encrypted backup you can restore on any device with a password. Network calls only go to targets you test or BGP data sources, everything else stays on your device.
