Tiny Shield

Tiny Shield monitors all network traffic on macOS 15 or later, presenting each connection with human‑readable hostnames instead of raw IP addresses. It aggregates sent and received data into visual charts, allowing users to see real‑time activity and identify which domains their Mac is contacting.

The tool lets users block unwanted traffic at multiple levels: specific domains or websites can be denied, and entire applications can be prevented from accessing the internet. It works with DNS‑Over‑HTTPS and can extract hostnames from browsers such as Chrome and Firefox, providing precise control over outbound connections.

Designed for developers, Tiny Shield runs as a system extension that operates with minimal performance impact, offering a lightweight, fast solution for network security and monitoring on macOS. It is distributed under a simple, one‑time license with two years of updates.
