Score: 6.0/10 (Innovation: 4, Technical: 6, Documentation: 8, Utility: 6)

Wafmeow is a Go-based WAF fingerprinting tool that ports wafw00f's 172-product fingerprint catalogue into a fast, concurrent CLI and importable library. It supports live scanning, offline analysis of saved HTTP responses and httpx exports, and structured JSONL/CSV output, making it useful for large-scale security pipelines. While the core idea is a port rather than a novel approach, the engineering around concurrency, evidence quality and pipeline integration is solid.

Target audience: security engineers, penetration testers, devops, backend developers
