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.

Export & customize

Export your data as CSV or JSON at any granularity, and switch the menu-bar item between live rate, today's total, and quota percentage.

Your network data never leaves your Mac.

Most network monitors phone home. Bytetally does the opposite: every byte is analysed locally, there's no account to create, and the app is fully sandboxed for the Mac App Store.

FAQ

Good questions.

What is Bytetally?+
Bytetally is a network monitor for macOS. It shows how much network data each app uploads and downloads, helps you stay under a data cap, alerts you to unusual activity, and can throttle or block an app's network access. All analysis happens on your Mac.
Does Bytetally upload or collect my data?+
No. Traffic analysis runs entirely on-device and no browsing content or traffic data ever leaves your Mac. There is no account. The only network request the app makes is to validate your purchase receipt.
Is Bytetally free?+
Yes — core monitoring is free. Pro features (full history, data caps, per-app control, auto-response, export) come with a free trial, then a subscription or a one-time lifetime purchase.
Does it work with VPNs and proxies?+
Yes. Bytetally recognises VPN tunnels and local proxies such as ClashX and attributes traffic back to the originating app.
What do I need to run it?+
A Mac running macOS 14 Sonoma or later. Bytetally is on the Mac App Store and fully sandboxed.
