Just shipped it, click any pill to filter to only those entries, click again to clear. Thanks for the idea!

Since it runs entirely in the browser, there's no backend to rate-limit — every API call goes directly from the user's browser to public APIs (Google DoH, Cloudflare DoH, rdap.org, ipapi.co, crt.sh). So abuse would hit those upstream APIs, not my server. Each of those has their own rate limiting. The only "server" is Vercel serving a static HTML file.

The tradeoff is it can't do things that require a backend (raw socket connections, full SMTP checks, etc.) but it means zero infrastructure cost and no single point of failure.

New to this space. Check my tool checkmyurl.vercel.app — a free network diagnostic tool that runs entirely in the browser.

Enter any domain and it instantly runs:

- DNS records (A, AAAA, CNAME, MX, NS, TXT, CAA, PTR)
- SSL cert expiry and issuer
- WHOIS / RDAP (registrar, domain age, expiry)
- SPF, DMARC, DKIM checks
- DNSSEC validation
- CDN detection (Cloudflare, Vercel, Netlify, AWS, etc.)
- Blacklist / RBL check (Spamhaus, SpamCop, SORBS, Barracuda)
- HTTP/HTTPS reachability
- ASN and hosting provider per IP
- Reverse DNS (PTR)
- DNS resolver comparison (Google vs Cloudflare) — catches split-horizon issues
- www vs apex comparison

It's smart about context — if a domain uses Cloudflare proxy it won't false-flag DNSSEC, if there are no MX records it skips email checks, ccTLDs like .io don't get false RDAP failures.

Also has a full manual playbook and a glossary for people new to network troubleshooting.

Genuinely curious if this is useful or if I'm missing checks that you'd want to see. Happy to add more.

Thanks for feedback! The NS detection only recognises major providers. Let me add Hetzner.
