A native macOS application for comprehensive network performance testing and diagnostics.
Run Apple's built-in network quality test with real-time progress, detailed results, and performance insights.
Compare results across multiple providers — Apple, Cloudflare, and M-Lab — to get a complete picture of your network performance.
Built-in tools for ping, traceroute, and DNS lookups.
Visualize your network path with geographic traceroute mapping.
Detect potential ISP throttling by comparing speeds with and without VPN.
Measure local network performance between devices on your network.
Track results over time. Export to PNG, CSV, JSON, or PDF.
