- Safe and soundCertificate, security headers, redirects and DNS

Type a domain such as example.com or paste a full link into the website checker, then press Check website. The full report opens on its own page. While every check runs at once you watch it happen: the test computers light up on a world map, each part ticks off as its answer lands, and a live feed shows what just came back. Most parts finish in five to ten seconds; Google's speed test takes up to 40.
- Pick where to check from under Check from: worldwide, or Asia, Europe, the Americas, the Middle East or Pakistan, with 5, 10 or 20 places.
- Read the top of the report first: a health score from 0 to 100, one sentence that says whether the site is up and in good shape, and a score for performance, availability, security, email and the domain.
- Scroll through the sections or jump to one from the bar that stays at the top. Each finding links to the section that explains it.
- Press Download PDF report to keep the whole report as a file, ready to send to a client or a developer.
When the address redirects, for example from http to https or to www, the checker follows it and reports on the page visitors really end up on.
What each section of the website health check shows
- Speed: Google's lab test in a mid-range phone or a computer, a score from 0 to 100, Core Web Vitals for real Chrome visitors, what would help most and every file the page loaded.
- Uptime: whether the site loads from each place, how long each step takes from finding the server to the last byte, and what to try when it does not open.
- Ping: round trip, packet loss and jitter from each place.
- Security: an SSL certificate check that shows who it is for, who issued it, how many days it has left and whether browsers trust it, plus a security headers check graded from A to F.
- Redirects: every hop of the redirect chain with its status code, the time it adds, loops and temporary moves.
- Technology: the CMS, shop platform, framework, CDN, analytics and other tools the site is built with.
- Domain: WHOIS data from the registry, with the domain's age, expiry, registrar, transfer lock and DNSSEC, and its DNS records.
- Email: SPF, DKIM, DMARC and mail servers, judged the way Gmail and Yahoo judge them.
- Traffic: the site's world rank by links and how Chrome's real visitors split between phones and computers.
Every section leads with charts: score rings, bars that show where a value sits between good and poor, a world map, timelines for the certificate and the domain, and donut charts for page weight, technology and devices. The raw numbers, records and commands sit under Full details in each section.
Good, needs work or poor: how website response time is rated
A place is rated good when the first byte of the page arrives within 0.8 seconds, needs work up to 1.8 seconds and poor after that, the limits Google uses for time to first byte. If one region is slow and the rest are fast, the server is far from those visitors and a CDN would help. If every place is slow and most of the time is the server preparing the page, look at caching or your hosting. The Speed tab then shows what the browser does after that first byte.
A page for each check
Some people search for just one part. The WHOIS lookup, the DMARC checker and the is it down checker are this same site checker, and their report opens at the section they asked for, so every answer is one scroll away whichever page you start on.
Privacy and limits
Uptime, ping, redirects and technology run on Globalping, a free network of probes from jsDelivr. Their results are public for up to six months, so the checker leaves out login details, the part after ? and paths that look private, unless you choose to keep them. DNS and email records are read from your browser through Cloudflare's resolver and WHOIS through RDAP. The speed test and Chrome's real-user report go through our server to Google. PieToolkit stores nothing about the sites you check; see the privacy page.
Every visitor gets 250 free Globalping tests an hour, and each place counts as one test. Sites on a private network, such as localhost or a 192.168 address, are refused.
Questions
Why are some parts empty for an IP address?
WHOIS still names who holds the address, but email and traffic belong to domain names, so the report leaves those sections out and scores the rest.
Can I test from my own country or internet provider?
Yes. Open More options and type a city, a country, a provider name or an AS number.
Can I share or save the report?
Press Download PDF report for a file with the health score, what to fix first and every section. The page address can be shared too; whoever opens it starts the check with one click, so the results are always fresh.
