Our take
A genuinely large DNS and email-security scanner — SPF, DMARC, DKIM, DNSSEC, TLS, subdomain-takeover, ~80 tools across 19 scoring categories — running free on Cloudflare Workers with no API key, and the hosted endpoint answers health checks. The catch is provenance: it's a solo pseudonymous developer with zero followers, the whole codebase (900+ TS files) materialized in about four months, and the license is source-available BUSL-1.1, not open source. Real and useful today; treat it as a young one-person project, not infrastructure.
