OpenPacketLoss vs iPerf Falcon

OpenPacketLoss-Server is a lightweight utility that transforms your computer into a dedicated network testing endpoint. By hosting the server on your own hardware, you can measure the precise quality of the connection between two points on your network, eliminating the unpredictable variables of the public internet. How to Use It Run the Server: Launch the app on a stable PC or laptop—this becomes your "target" device. Connect the Client: Use any OpenPacketLoss client on a different device (such as a phone, tablet, or another PC). Troubleshoot: Start the test to view real-time packet loss, jitter, and latency. Why Run Your Own Server? Testing against a server you control allows you to isolate your hardware. You can instantly determine if connection drops are caused by faulty cables, weak Wi-Fi, or router congestion, or if the issue is actually with your Internet Service Provider (ISP).

iPerf Falcon turns professional network throughput measurement into a clear, approachable native app. Check Wi-Fi coverage, LAN wiring, routers, NAS devices, servers, or home broadband—and use real measurements to find the bottleneck. This is not a conventional speed test tied to someone else's server. Connect to an endpoint you choose, let this device listen, or automate the full test path over SSH. You control both the target and the test. Three ways to get started Connect • Enter any iPerf host and port, or choose from 8 free public servers • Check port reachability with one tap; Falcon Pro can also save and pin frequent targets Listen • Turn your iPhone, iPad, or Mac into an iPerf server • Listen on all interfaces or choose an IPv4 address from Wi-Fi, Ethernet, cellular, or VPN • See exactly which address and port the other device should use • Start once and accept multiple client connections continuously, with each session saved separately until you stop listening SSH (Falcon Pro) • Connect to OpenWrt, Linux, or another SSH device; start the iPerf server, run the test, and clean up automatically • Authenticate with a password, an OpenSSH private key, or no credential on a lab device configured to allow it • Run the server remotely, or listen locally and have the SSH endpoint connect back Professional measurement without the friction • Both iPerf3 and iPerf2 engines, switchable in one place • TCP and UDP with upload, download, and bidirectional modes • A graphical form for direction, protocol, duration, parallel streams, bitrate, and more • A live speed gauge and throughput chart—tap the chart to inspect any moment • Separate upload and download speeds, charts, and metrics for bidirectional tests • Live Ping, TCP RTT, retransmissions, UDP jitter, and packet loss • Raw iPerf output whenever you need it, plus a searchable parameter and command reference Keep the results that matter • Save every run automatically, or keep only the tests you choose • Add notes, search instantly, and rerun with the same configuration • Export individual results as CSV or JSON, or create a shareable result card Falcon Pro One purchase unlocks these features on iPhone, iPad, and Mac: • SSH remote orchestration • Advanced graphical options and iPerf command-line configuration—paste a command to parse and synchronize the graphical form, then save complete commands for quick reuse • Five built-in scenarios for VoIP, 4K streaming, gaming, NAS backup, and Wi-Fi roaming, plus custom presets • Saved targets and SSH endpoints • Charts and metric comparisons for up to 6 runs, plus batch history export Designed for Apple devices Falcon stays focused on iPhone, while iPad landscape and Mac use a two-column layout that keeps parameters and results visible together. Light and dark appearances are supported, along with Simplified Chinese, Traditional Chinese, English, Japanese, Korean, German, French, Spanish, and Russian. Privacy first No account is required, and there are no ads or analytics trackers. Test history stays on your device. SSH passwords and private keys are stored only in the system Keychain. Falcon connects only to test targets you choose.
