iperf3 vs 3X Client

iperf3 Mobile is a professional LAN throughput tool for home labs and power users. It embeds open-source iperf3 so you can run real, wire-compatible client and server tests across your local network, not a consumer internet speed test. ONE APP, CLIENT AND SERVER • Run as a client against any stock iperf3 server (Mac, Linux, NAS, or another device) • Run as a foreground server so phones, tablets, Macs, or Apple TV can be the other end of the path • One active test at a time, matching classic iperf3 behavior TEST THE WAY YOU ALREADY DO • TCP and UDP • Upload, download (reverse), multi-stream, and bidirectional • Live throughput chart plus UDP loss and jitter where applicable • Duration presets, stream count, and UDP target bitrate • Default port 5201, the same default as stock iperf3 FIND OTHER DEVICES • Bonjour discovery for other iperf3 Mobile servers on your LAN • Always enter a hostname or IP for stock iperf3 (-s) peers SHORTCUTS AND AUTOMATION • Run client tests from the Shortcuts app with host, port, duration, streams, protocol, and more • Start or stop the in-app server from Shortcuts (server keeps the app foreground while listening) • Structured results return throughput for multi-step automations and Siri BUILT FOR APPLE PLATFORMS • Universal purchase for iPhone, iPad, Mac, and Apple TV • tvOS UI sized for the living-room endpoint • Mac as a convenient always-reachable lab peer while the app is open PROPER TOOLING • Embeds upstream iperf3 (esnet/iperf); open-source license included in the app • Local Network access is used only for tests and peer discovery Need a quick start? Start the server on one device (or run stock iperf3 -s on a Mac/NAS), then point the client at that host and port.

3X Client is a native iOS administration application for managing 3x-ui server panels. Features: - Client Management: Edit, update, and manage inbound client configurations, data usage limits, expiry dates, and IP limits. - Server Status: View overall system health, including CPU load, memory usage, disk space, and network throughput. - Log Viewer: Read live server logs to inspect system events and troubleshoot connections. - Protocol Support: Visualizes VLESS, VMess, Trojan, Shadowsocks, and WireGuard inbounds configured on your server. Requirements: Requires a running 3x-ui server instance. This app is an administrative interface and does not provide built-in VPN server infrastructure or proxy connections.
