A macOS Activity Monitor alternative that actually explains things
Sysplained is a free, native macOS app that turns cryptic terminal output into a clear visual dashboard. Where Activity Monitor shows raw numbers for processes and a little network activity, Sysplained covers 12 views — network interfaces, listening ports, connections, DNS, routing, processes, disk, and more — and explains, in plain English, what each one means. Think of it as Activity Monitor with a wider lens and a built-in guide.

Why people switch
- It explains, not just measures.Every view comes with contextual hints and a glossary, so you understand what you're looking at instead of guessing.
- It covers the network.Interfaces, listening ports, connections, DNS, routing, ARP neighbors, and Wi-Fi — none of which Activity Monitor surfaces well.
- It's private and lightweight.~11 MB, all processing local, no telemetry, no account. Runs only standard macOS commands through a strict allowlist.
- No terminal required.You get the same information ifconfig, netstat, lsof, and dig provide — presented visually and explained.
