These signals show the company serving the site. A reseller or an agency may be the one paying for it.
How the check works
Every site leaves a trail: where its name points, who owns the server, what the server calls itself and what the platform adds to each page. We read all of it in one go.
DNS and network
Where the site's name points, the network that owns that IP address, and the nameservers that answer for the domain.
The server's own name
Hosting companies name their servers, and that name often gives the host away even when the IP belongs to a big data center.
Platform fingerprints
One visit to the home page reads the headers and markup that platforms like Kinsta, WP Engine, SiteGround, Hostinger and Cloudways leave.
Questions
How do you find out who hosts a website?
We look up the site's DNS and the IP address it points to, find which network owns that IP, read the server's own name (reverse DNS), check the nameservers, and fetch the home page once to read the headers and markup that hosting platforms leave behind. The strongest signal wins: a platform's DNS alias or fingerprint first, then the server name, then the network.
Why does it say the site is behind Cloudflare?
Cloudflare, Fastly, Sucuri and other CDNs answer for the sites behind them, so the address everyone sees belongs to the CDN, not the host. When a platform still shows through, such as Kinsta or WP Engine headers, we name it. When nothing shows, we say the host is hidden instead of guessing.
What does it mean when a site runs on DigitalOcean, Vultr or AWS?
Those are cloud providers that rent servers. The owner may run the server themselves, or use a managed platform such as Cloudways that sets up and looks after cloud servers for them.
How accurate is it?
High confidence means a signal that only that host leaves, such as its own DNS alias, its server names or its platform headers. Likely means a good clue, such as the nameservers or a cache plugin a host installs for its customers.
Is it free?
Yes, with up to 30 checks an hour from one connection. Each result has its own link you can share.
Found the host. Is it any good?
We test hosts on our own WordPress sites, from 9 regions, and publish the numbers.
