Find out what stack any website is using
Hoverify is a tech stack checker that reports the frameworks, CMS, analytics and plugins a site runs, then keeps going into hosting, DNS, SSL and WordPress details. When a client asks what their old site was built on, this is where you look.
What stack is this website using?
Site Stack opens on the technologies and keeps going: where the site is hosted, what its DNS says, which certificate it presents and, on WordPress, which theme and plugins are installed.
Technologies
Frameworks, libraries, CMS platforms, analytics and plugins, each with a confidence score and a version number where the site exposes one.
Hosting
The hosting provider, server IP, ASN, IP range and ISP, down to the city, region and local time.
DNS
A, AAAA, CNAME, MX, TXT and NS records, with their values and TTLs written in units you can read.
SSL
The certificate, who issued it, how long it's valid and which TLS version the server negotiated.
WordPress
The active theme with its author, version and preview, plus installed plugins with icons, ratings and premium badges.
Confidence scores. Every detection says how sure it is on a 0 to 100 scale, so you can tell a fingerprint from a guess.
Versions. Where a site exposes the version it's running, Hoverify reports it alongside the name.
Certificates. Issuer, validity window and TLS version, read off the certificate without a terminal.
The details that decide whether you take the project
Knowing a site runs React is mildly interesting. Knowing it's on shared hosting, behind a certificate that expires in three weeks, running a theme the author abandoned, is the part that changes your estimate.
Where it actually lives
The hosting provider, server IP, ASN, IP range and ISP, with the location down to the city and its local time. Useful when a site feels slow from one continent and fine from another.
WordPress, in detail
The active theme with its author, version and preview, and the installed plugins with icons, ratings and a badge on the premium ones. It's the fastest way to see what a migration is really carrying.
Export a report clients can read
Turn the whole stack into a document you can send. Clients rarely want a screenshot of a browser panel, and this saves you rebuilding one in a slide deck.
Five sections. Hosting, technologies, DNS, SSL and WordPress each get a checkbox, so you send only the parts that matter.
PDF or JSON. One switch. PDF for the client, JSON for the spreadsheet or the script.
One click. Hoverify builds the report from what it already read, so nothing is fetched twice.
Six record types. A, AAAA, CNAME, MX, TXT and NS, each with the value the resolver returned.
Nameservers. The NS records tell you who a domain delegates to, which is often the host you were looking for.
Readable TTLs. Record lifetimes in hours and minutes rather than raw seconds you have to divide.

Frequently Asked Questions
Have a question we haven't answered? Get in touch.
How do I find out what stack a website is using?
Open the site and run Site Stack. It reads the page and the response for known signatures and reports the frameworks, libraries, CMS, analytics and plugins it recognizes, each with a confidence score and a version number where the site exposes one.
How accurate is the detection?
It's inference, not a guarantee. Detection runs on the open-source webappanalyzer fingerprint set, so it finds what a site reveals through markup, script URLs, headers, cookies and global variables. A site that bundles everything or sits behind a proxy will show less, and the confidence score tells you when a match is a guess.
Does it check DNS and SSL too?
Yes. Site Stack pulls A, AAAA, CNAME, MX, TXT and NS records with their TTLs, and reads the SSL certificate along with its issuer, validity window and TLS version. Those lookups go out to public DNS and certificate services, since a browser extension can't resolve them on its own. It does not do a WHOIS lookup, so there is no registrar.
Can I export the results?
Yes. Tick which of the five sections you want in the report, then export it as PDF or JSON. The PDF is the one clients tend to want; JSON is for when the stack is going into a spreadsheet or a script.
Does it work on WordPress sites specifically?
WordPress sites get their own tab. Hoverify identifies the active theme with its author and version, and lists installed plugins with icons, ratings and a badge on the premium ones.
Which browsers does the tech stack checker work in?
Chrome, Edge, Brave and other Chromium browsers are fully supported. Every tool runs in the Firefox build too; it carries an experimental label because Chromium gets fixes and new features first.
Is the tech stack checker free?
Site Stack is one tool inside Hoverify, a paid extension with a 14-day refund policy that covers you if it doesn't earn its place. The tool isn't sold or trialled separately. One license runs in 3 browsers at a time and nothing auto-renews. See the pricing.
Know what you're inheriting before you quote
Hoverify puts the stack checker next to the SEO audit, the CSS inspector and the screenshot tools. Read the stack, run the audit and export both as reports the client can read without you in the room.
- 3 browsers per license
- 14-day refund
- No auto-renewal
