How it works

From a URL to a full stack

A fast public-page inspection with clear limits

01

Enter a public URL

Paste a homepage, landing page, or article URL. The checker normalizes the address before running the lookup.

Inspect visible clues

SearchVector checks public page signals such as scripts, headers, metadata, tags, fonts, and common platform fingerprints.

Review the stack

Read the detected categories, then use the findings to guide competitor analysis, migration planning, or a deeper SEO audit.

Workflow

Built for Practical Research

A technology lookup should be useful even when a site hides part of its stack

Hidden headers, bundled code, blocked crawlers, and obfuscated assets can limit what any technology checker can prove.

Website technology questions

Common questions about website technology checking

Is this website technology checker free?

Yes. You can run a website technology check without creating an account. It is part of SearchVector's free SEO toolkit.

How does the checker identify a site's tech stack?

The checker reviews public signals such as HTML, script paths, meta tags, response data, tracking snippets, font assets, and common technology fingerprints.

What technologies can it detect?

It can detect many CMS platforms, ecommerce systems, analytics tools, tag managers, CDNs, JavaScript libraries, SEO plugins, font services, and related front-end signals.

Can a technology checker miss something?

Yes. A site can hide headers, bundle scripts, block crawlers, or run private backend services that are not visible from a public page scan. Treat unclear results as leads for deeper review.

Can I check competitor websites?

Yes. Use the tool to check public pages from competitors, prospects, or vendors, then combine the findings with SearchVector's keyword research, audits, and rank tracking.
