iPerf3 Client & Server vs Punktfunk

Requires access to an iPerf3 server (local, VPN, or remote). This is not a general Internet speed test. iPerf3 Client & Server brings the standard iPerf3 tool to iPhone and iPad with a clean, native UI. One purchase also unlocks the Mac version. Measure real throughput across Wi-Fi, cellular, VPN, or LAN. Compare routers and access points, validate ISP or VPN changes, and find bottlenecks. Key features: - Client and server modes - TCP/UDP tests, including bidirectional and reverse - Advanced controls: duration, parallel streams, bandwidth caps, window size, MTU - Shortcuts automation + x-callback-url for power users - Saved server profiles and favorites - History with charts and CSV/JSON export - Detailed metrics: throughput, latency, jitter, packet loss Automate repeatable workflows with Apple Shortcuts or x-callback-url (run tests, fetch results, and chain actions). Built for network engineers, sysadmins, and power users who need accurate, repeatable results.

Punktfunk is the next generation of local game streaming. Stream from your Linux PC, headless server or laptop to your Apple devices — with low latency and built-in support for virtual displays. That means the resolution matches exactly the device you are streaming to. Windows hosts are supported as well. Both our client apps and the server/host are open source. Punktfunk sets itself apart from existing solutions through lower latency, which we achieve with our own QUIC-based protocol. More features: • Comprehensive DualSense controller support (adaptive triggers, LEDs and rumble) • Xbox controller support • Microphone passthrough: optionally forward the microphone from your client to the host • Heavily optimised client with Metal-based rendering • 1 Gbps+ ready: a lot of work went into supporting high bitrates, so high resolutions and refresh rates are possible. Requires a good network/Wi-Fi • (Experimental) Browse the host's game library on the client and launch games directly • Windows hosts: 10-bit colour and HDR support • Statistics: glass-to-glass latency measurement • Mouse and keyboard support
