Fast Network Speed Test — three speed engines in one app: Netflix Fast.com, our internet speed test, and your local network. Pick a mode, hit Start, and watch the live 250° arc gauge climb. Fast Network Speed Test bundles three independent measurement engines behind one premium speedometer UI — so you can benchmark your real internet connection, the Netflix CDN edge closest to your ISP, or the raw throughput between two PCs on your LAN, all in the same app. MODES ★ Fast.com mode: the real Netflix Open Connect speed test. It discovers the edge caches deployed inside your ISP and streams from them — the same numbers Fast.com shows, measured by our own pure C engine. ★ Internet mode: our own speed engine via speed.scorpiox.net — download, upload, ping, and jitter in one run. ★ LAN mode: raw PC-to-PC throughput, latency, and jitter for 1 GbE / 10 GbE networks, with a built-in server you can start on the second machine. KEY CAPABILITIES ★ Three selectable mode tiles — pick Fast.com, Internet, or LAN with one tap ★ Live 250° arc speedometer with 96pt readout and 10 Hz tick animation ★ Real-time throughput sparkline while the test runs ★ Four metric cards: ping, jitter, download, upload ★ Instant cancellation in under 50 ms — abort any test mid-run ★ Built-in LAN server: start it on one PC, benchmark from the other ★ Test history: last 20 runs with mode, timestamp, and full results ★ Raw JSON export: copy any result for diagnostics or logging ★ Privacy-first: no ads, no telemetry, no account required PERFECT FOR • Checking what speed your broadband plan actually delivers • Comparing Netflix edge performance against your own ISP • Verifying 1 Gbps, 2.5 Gbps, and 10 Gbps LAN line rates • Measuring latency and jitter before a big match or video call • Diagnosing slow connections, bad cables, and bottleneck switches MODERN WINDOWS EXPERIENCE Built with WinUI 3 in a dark cyber-obsidian theme with electric cyan gauges, centered layout, and full localization in 13 languages. Your internet, your LAN, your numbers — measured the honest way.
