About:
Fastrace is a lightweight, dependency-free traceroute utility implemented in pure C. It provides network path visualization by sending packets with increasing TTL values to map the route to a destination. Its minimal implementation makes it highly portable and suitable for embedded systems or environments where standard traceroute is unavailable.
Key Features:
  • Zero dependencies (pure C implementation)
  • Lightweight and highly portable
  • Simple command-line interface
  • Fast execution and low resource usage
Use Cases:
  • Network troubleshooting and path analysis on resource-constrained systems
  • Embedded systems diagnostics where standard tools are unavailable
  • Learning and educational purposes for network programming
Alternatives:
  • traceroute – Standard system utility, usually pre-installed but may have dependencies or larger footprint
  • mtr – More feature-rich with continuous monitoring capabilities, but heavier dependency tree
