Domain Intelligence Scraper

romy/domain-intelligence-scraper

Domain Intelligence Scraper performs comprehensive passive OSINT on any domain — combining 8 free data sources into one output record: WHOIS, RDAP, DNS records, subdomains (from 3 independent sources), open ports + CVEs, passive DNS history, IP geolocation, and HTTP security headers

Certificate Transparency Log Firehose

jungle_synthesizer/certificate-transparency-log-firehose-scraper

Streams newly-issued certificates from public CT logs (Google, Cloudflare, DigiCert, Sectigo, TrustAsia) with a keyword/pattern watch-list match — delta-since-last-run, not a one-domain lookup.

Day-zero startup leads from Certificate Transparency: crt.sh finds domains whose FIRST TLS cert was just issued, we enrich each new site's OWN website with MX/DNS-verified emails + phones + socials + tech stack + A-D launch-readiness. Be first to a newly-launched business. Per-result, no keys.

New Domain Delegations — Daily Domain Monitoring Feed

oswaldocarabano/new-domain-delegations

Daily domain monitoring feed of names that just appeared in registry zone files, filtered by keyword or TLD. Often searched as a newly registered domains list: we report zone entry, the earliest public signal, which is not quite the same thing. The README explains why.

Domain Expiration, DNS & SSL Intelligence Auditor

unrivaled_fortress/domain-whois-expiration-dns-intel

Audit domain age, expiration dates, DNS records (A, MX, NS), and SSL certificates. Built for domain investors, SEO drop-catchers, and cybersecurity analysts.

RSS Feed Reader - Any RSS/Atom Feed to JSON

rowfeed/rss-feed-reader

Convert any RSS 2.0 or Atom feed URL into clean JSON: one row per item with title, link, published date, author, summary and categories. Bad feeds become error rows, not crashes.

Checks GitHub Pages sites on custom domains: DNS records for the apex and www, HTTPS status of each required path, the HTTP-to-HTTPS redirect, the certificate host name, dangling-domain risk, and the Pages API state when a token is given. Gives PASS, WARN

Monitors any RSS/Atom feed, JSON Feed, or Substack publication archive and returns structured post rows with title, URL, publish date, summary, tags, word count, and paywall status.

Check domain availability, WHOIS registration data, and DNS records (A, AAAA, MX, NS, TXT, CNAME) for any list of domains. Identify expired domains, find nameservers, detect mail providers, and analyze domain infrastructure. Uses public DNS APIs — no API key required.
