NetCurb helps you control data use on your Mac, especially on phone hotspots and capped connections. I burned through 1GB of data while I was travelling because some Mac process decided to update something. This app helps prevent that from happening. See per-app uploads and downloads, block background apps, and set data allowances for home, work, or travel. Free includes monitoring, unlimited manual blocking, usage history, CSV export, and limits for one app.

Could you build this?
No Real-time per-app network monitoring and traffic blocking on macOS requires specialized Apple Network Extension entitlements and low-level system daemon architecture.
What it would actually take: A production version requires Swift or Objective-C interacting with Apple's NetworkExtension framework, specifically NEFilterDataProvider or NEAppProxyProvider, alongside a privileged system helper daemon. The critical hurdles are securing Apple-approved developer entitlements for content filtering and reliably managing process-to-socket attribution without kernel panics or connection leaks. This requires deep systems-level macOS engineering and privilege-separated architecture.
