What is it?

NetFluss is a macOS menu bar app that shows real-time upload and download rates for your network adapters, along with total WAN bandwidth reported by supported routers. A popover lists per-adapter details, Wi-Fi information, IP addresses, and the top apps currently using the network.

Beyond live rates, it keeps historical statistics by adapter and by app over ranges from one hour to one year, and includes a Network Slice window that shows which remote hosts, services and apps are active right now. It also offers a speed test with M-Lab and Cloudflare providers, and a DNS switcher, Wi-Fi network switcher and a built-in VPN client that supports OpenVPN, WireGuard and IKEv2/IPsec/L2TP.

Supported routers are Fritz!Box, UniFi, OpenWRT and OPNsense. A Windows version is in public beta, built with the same feature set.
