SpeedPing

Network diagnostics usually means four terminal windows and a prayer. SpeedPing folds the essentials into one lightweight desktop app for macOS, Windows and Linux.

Three tools, one window: realtime multi-host ping monitoring with live latency, packet-loss and jitter graphs; integrated iperf3 bandwidth testing (TCP/UDP, reverse mode, parallel streams, custom parameters) with live throughput graphs; and an animated hop-by-hop traceroute visualization with per-hop latency — the network path as a picture instead of a wall of asterisks.

Stable releases plus nightlies. Built for sysadmins, homelabbers, and anyone who has ever said "the internet feels weird today" and wanted evidence.
