  "github_readme_excerpt": "# Fastrace\n\nFast, dependency-free traceroute in pure C. Minimal syscalls, clear output, significantly faster than standard traceroute.\n\n## Features\n\n- **IPv4 and IPv6** dual-stack support\n- **Multiple probe modes**: UDP (default), ICMP Echo, TCP SYN\n- **Output formats**: Text (default), JSON, CSV\n- **Performance metrics**: RTT percentiles, jitter, statistics\n- **Adaptive concurrency**: Automatic window sizing based on network latency\n- **Zero dependencies**: Only libc + raw sockets\n\n## Performance\n\nFastrace is designed for speed. By using non-blocking sockets, batch I/O, concurrent probing, and optimized syscalls, it completes traces significantly faster than the standard `traceroute` utility.\n\n### Benchmark: `google.com`\n\n| Tool         | Hops | Time   | Response Rate |\n| ------------ | ---- | ------ | ------------- |\n| **fastrace** | 13   | ~1.5s  | 74.4% (29/39) |\n| traceroute   | 11   | ~30s   | \u2014             |\n\n**fastrace** completes the trace **~20x faster** while providing richer output including load-balanced path detection.\n\n\u003cdetails\u003e\n\u003csummary\u003eFull output comparison\u003c/summary\u003e\n\n**fastrace:**\n\n```\nsudo ./fastrace google.com\nfastrace 1.0.0\nTracing route to google.com (142.250.180.174)\nMaximum hops: 30, Probes per hop: 3, Protocol: UDP\nTTL \u2502 IP Address                              (RTT ms)    Hostname\n\u2500\u2500\u2500\u2500\u253c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\n1   \u2502 \u2192 192.168.1.1                           (  6.15 ms)\n2   \u2502 * * * (timeout)\n3   \u2502 * * * (timeout)\n4   \u2502 \u2192 185.89.159.5                          ( 14.77 ms)\n5   \u2502 \u2192 37.26.80.129                          ( 14.68 ms)\n6   \u2502 \u2192 193.77.91.225                         ( 29.88 ms) bsn-77-91-225.static.siol.net\n7   \u2502 \u2192 193.77.107.46                         ( 31.69 ms) bsn-77-107-46.static.siol.net\n8   \u2502 * * * (timeout)\n9   \u2502 \u2192 142.250.180.174                       ( 37.91 ms) mil04s44-in-f14.1e100.net\n      \u2514\u2192 142.251.235.178                       ( 39.32 ms)\n      \u2514\u2192 192.178.44.134                    ",
