Network monitor for macOS

See where your Mac's network data goes.

Bytetally tracks every app's bandwidth, keeps you under your data cap, and lets you throttle or block any app — all on your Mac. Nothing is ever uploaded.

See the websites, not just the apps

Beyond knowing which app is using data, see the websites it talks to — and which apps reach a given website. Traffic routed through a local proxy like ClashX or Surge still resolves to the real destination.

Both directions: app → websites, website → apps

Data caps & alerts

Set a monthly, weekly or daily cap — and a separate budget for each Wi-Fi network. Bytetally warns you before you go over, and flags unusual uploads.

Control any app, one click

Right-click an app to disconnect it, set an up/down speed limit, or give it its own data quota — no rules to write.

Control a single website

When one website is eating your data, block or throttle just that one — no need to cut off the whole app. A rule can target an exact host, and the Rule Centre shows how many times each rule actually fired.

Scope a rule to one app, or all apps

Overage auto-response

When a cap is reached, Bytetally can automatically cut the network or throttle it — so you never blow through a limit while you're away from the keyboard.
