Score: 5.7/10 (Innovation: 5, Technical: 6, Documentation: 5, Utility: 6)

CertObserver provides a Certificate Transparency search engine that groups related certificates and includes deduplication of pre-certificates and final certificates. It is interesting because it addresses a known gap in monitoring TLS certificates with features like DNS scope options and near-real-time data, useful for security and domain management.

Target audience: security engineers, devops, domain owners
