I built a free domain health-check tool — enter a domain, get a scored diagnostic report
Hi all,
I built a small free tool and thought some of you might find it useful:
Enter a domain and it generates a one-page health report: WHOIS info, DNS records, mail security (SPF/DKIM/DMARC), TLS/SSL config, security headers and web availability — with an overall score, grade and fix suggestions.
For example, lowendtalk.com scores 85/100, grade A:

It's free, no signup. Part of TCPLab (tcp.lc), a network toolbox I'm building for devs and sysadmins — IP tools, ping/port/SSL checks and a few others.
Happy to take feedback or bug reports here. Thanks!
Thanked by 1dosai

why ?
Fair question. I built it for quickly checking my own and client sites (one page instead of jumping between 5 different tools), and figured others here running servers might find it handy. It's free, no signup — just sharing in case it's useful. Open to feedback.
