NetMute

Apps track you. NetMute hangs up.

NetMute is a per-app firewall for macOS that sits in your menu bar and shows which app is contacting which domain right now. One click takes any app offline. App X-Ray lists every connection per app and grades each app from A to F. Tracker Shield blocks known tracker and ad domains system-wide. Per-app data limits protect you on hotspot and tethering, profiles switch automatically per Wi-Fi, and the weekly report shows who is listening the most. Built on Apple's Network Extension: local-first, no account, no subscription — all network analysis runs entirely on your Mac.

You decide what your Mac is allowed to send

Every app on your Mac quietly contacts servers in the background — analytics, telemetry, ad networks, often even when you're not using it. NetMute is a per-app firewall for macOS: you see which app talks to whom, and switch off what shouldn't get through with a click. No account, no cloud, everything stays on your device.

NetMute — the world map shows where your Mac sends data

See where in the world your Mac sends data

The heart of the new version is a world map: it shows which countries your apps connect to, shaded by how much data went to each. Tap a country and you see *which* app is sending there — ranked by volume.

The important part is how it works: the map is built from a country database that lives inside the app (around 2.5 MB), assembled from the public regional-registry files that govern the internet's address allocation. No third-party geolocation service, no online lookup — looking at where your Mac connects never reveals where you are.

Cryptic hostnames, made readable

App X-Ray translates unreadable server names into the service behind them: `googlevideo.com` becomes YouTube, with the server's country flag and exactly how much was sent and received. A list of addresses turns into a sentence you can actually read.

What it sees — and what it can't

NetMute sees where a connection goes and how much moved — never what is inside it. The encryption happens inside each app before the data reaches the filter; the contents are unreadable by design. That's not a limitation — it's the promise: it sees the address on the envelope and the postage, never the letter.

More than just seeing

Tracker Shield — blocks known tracking domains, per app or system-wide.
Data limits — cap how much an app or your whole Mac may use; reset-proof counting, optional hard stop. Handy on a metered hotspot.
Per-network usage — home Wi-Fi and hotspot kept apart, with hotspot detection.
Reports — Today / week / month, sent and received split out.

Small, deliberate, fair

NetMute is an indie app, built by one person in Munich. No subscription, one-time price, no account, no data collection. Seeing is free — the Dashboard, App X-Ray and Reports open without Pro. Only system-wide blocking is the Pro feature.
