Install: brew install fragroute

About:
Fragroute is a network tool that intercepts, modifies, and rewrites outgoing TCP packets for a specified host. It operates by bridging network traffic, allowing users to inject delays, drop packets, or duplicate connections to test application resilience. This utility is essential for simulating adverse network conditions and evaluating how network services behave under stress.

Key Features:

Intercepts and rewrites egress TCP traffic
Configurable packet manipulation (drop, delay, duplicate)
Bridging capability for transparent network interception
Lightweight and command-line driven

Use Cases:

Simulating poor network quality to test application robustness
Security auditing of network services under adverse conditions
Debugging network protocol behavior

Alternatives:

tc (Traffic Control) – Built-in Linux utility for traffic shaping; more complex syntax but native integration.
netem – Linux kernel module for network emulation; often used via the 'tc' command.
