Site Stack

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 lists the technologies a site runs and keeps going: where it's 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, grouped by category. The PDF report adds versions and a confidence score for each.

Hosting

The hosting provider, server IP, ASN 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 chain, who issued each certificate, when it expires and whether the chain has problems.

Theme (1)

GeneratePress

Author: Tom Usborne

Version: 3.6.1

GeneratePress is a lightweight WordPress theme built with a focus on speed and usability.

Plugins (3)

Autoptimize

Rating: 4.7

Version: 3.1.16

Autoptimize makes optimizing your site really easy. It can aggregate, minify and cache scripts and styles.

Contact Form 7

Rating: 4.0

Version: 6.2.3

Contact Form 7 is a plugin designed to be a practical tool for all WordPress users who embrace free software.

Classic Editor

Rating: 4.9

Version: 1.7.0

Classic Editor is an official plugin maintained by the WordPress team that restores the previous editor.

Confidence scores. The PDF report rates each detection from 0 to 100, and a low score marks a guess.

Versions. Where a site exposes the version it's running, the export lists it next to the name.

Certificates. Issuer, validity window and chain issues, read off the certificate without a terminal.

Beyond the framework list

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 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.

Five formats. Markdown, PDF, JSON, CSV or plain text. PDF for the client, CSV for the spreadsheet.

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.

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. The PDF export adds a confidence score for each and the version where the site exposes one.

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. The PDF export scores each match from 0 to 100, which tells you when one is a guess.

Yes. Site Stack pulls A, AAAA, CNAME, MX, TXT and NS records with their TTLs, and reads the SSL certificate chain with each certificate's issuer and validity window. 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.

Yes. Tick which of the five sections you want in the report, then pick a format: Markdown, PDF, JSON, CSV or plain text. Markdown is the default and goes to the clipboard, which suits a chat or a ticket. The PDF is the one clients tend to want, and CSV or JSON is for when the stack is going into a spreadsheet or a script.

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.

Chrome, Edge, Brave and other Chromium browsers, and Firefox. Every tool runs in both builds, and one license covers them. One caveat, which the export dialog itself shows: PDF generation is better in Chrome than in Firefox, so build the PDF report there if it has to look right. The other formats don't depend on the browser.

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.

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.
