A real Chrome load on mobile or desktop from our probe locations: performance score, Core Web Vitals, the loading filmstrip and the biggest savings.
Diagnostics we run every day when clients ask “why is my site slow” or “why does my email land in spam”, open to everyone.
A real Chrome load on mobile or desktop from our probe locations: performance score, Core Web Vitals, the loading filmstrip and the biggest savings.
A real Chrome load on mobile or desktop from our probe locations, with the same settings as Google PageSpeed: performance score, FCP, LCP, TBT, CLS, the loading filmstrip and where the biggest savings are. Plus network timing per location (median of 3 runs) and a page analysis from the page code.
Query Cloudflare, Google, Quad9 and OpenDNS at once and compare the answers.
A forgotten renewal takes down site and mail overnight. Reads registry data over RDAP, and for .rs over WHOIS from a probe location.
See how your site looks on the NEW server before switching DNS. No temporary subdomain: we fetch the site from the IP you enter, sending the real Host header, and serve it under a temporary link.
MX, SPF, DKIM and DMARC with a deliverability score and concrete fixes.
Six DNSBL lists (Spamhaus, SpamCop, Mailspike…), each first verified on its own test address. Leave empty to check your own address.
Missing or mismatched PTR is a leading cause of mail landing in spam, and almost nobody checks it. Verifies the full round trip.
Chain trust as a browser sees it, expiry, names, protocol and key.
HSTS, CSP, X-Content-Type-Options and more, scored with their values checked, after following redirects.
Checks a TCP port from outside, from every location. Answers the most common support question: is a firewall blocking me?
Checks availability from every probe location at once. Up from some but not others means a network or geo-block issue, not a site outage.
mtr shows loss and latency per hop, so you see WHERE traffic is lost. TCP traceroute passes through ICMP filters. Requires a probe node.
Your public IPv4/IPv6 address with reverse DNS.
LimaCloud is tuned so your site and mail pass every one of these checks, and we prove it with a benchmark before and after migration.
