Netutilus

One click answers the classic question: is it your Wi-Fi or your provider? Netutilus probes your router, times your DNS, tests direct internet addresses, and checks web reachability. It tells you exactly where the problem lies and lets you export a report card (PNG, CSV, JSON, or text) that you can easily attach to a support ticket with your ISP.

Keep your public IP, country, ISP, and VPN state just one click away. See the exact moment your VPN drops or your IP changes, get a warning when IPv6 leaks around your tunnel, and keep a local log of every change. Everything stays strictly on your Mac.

Measure download, upload, latency, and jitter over four parallel streams. Netutilus also calculates a bufferbloat grade from A+ to F, revealing how much your latency rises under load—the number one cause of lag in video calls and games. Track your network's performance over time using automated scheduled tests, visual history charts, and detailed ISP reports.

Know the moment someone new joins your Wi-Fi. The LAN Scanner learns your trusted devices and sends an instant notification when an unknown one appears. Trust or ignore new connections right from the alert—with no cloud accounts, tracking, or extra hardware required.
