Is Website Technology Detector free to use?

Yes. Website Technology Detector is free, has no usage cap and does not require an account. There is no paid tier that unlocks extra output.

Does my data get uploaded to a server?

No. The tool is a JavaScript function that runs inside your browser tab. Nothing you paste or drop in is transmitted, logged or stored by us.

Do I need to create an account?

No account, no email address and no sign-in. Open the page and start working.

Does it work on a phone or tablet?

Yes. The interface is responsive and works in mobile Chrome, Safari, Edge, Firefox and Samsung Internet. You can also install Toolspea as an app from the browser menu.

Can I use the output commercially?

Yes. You keep every right you already had over the input, and we claim nothing over the output.

How accurate is detection?

Matches are evidence-based: each result shows the string or header that triggered it, so you can judge the confidence yourself.

Can I download the whole site afterwards?

Yes — Website Cloner downloads the pages and assets of the same public site into an offline ZIP.

Website Technology Detector

See the CMS, framework, analytics and hosting signals behind any public page.

Public pages only. Toolspea fetches the page for you because a browser tab cannot read another origin directly — nothing you enter is stored.

What is Website Technology Detector?

Website Technology Detector fetches a public page and matches its HTML and response headers against known signatures for content management systems, JavaScript frameworks, CSS toolkits, analytics scripts, CDNs and web servers, then lists what it found with the evidence for each match.

How to use it

1Paste the address of the public page you want to inspect.
2Run the detection — Toolspea fetches the page once.
3Read each group: CMS, framework, analytics, hosting and server.
4Check the evidence column to see exactly what matched.

Features

Signature matching across HTML markup and response headers
Groups results by CMS, framework, library, analytics and infrastructure
Shows the matching evidence rather than an unexplained verdict
Reports WordPress theme and plugin folders when they are exposed

When people use it

Competitive research

Understand what a competitor built on before proposing a replatform.

Pre-sales scoping

Confirm whether a prospect's site is WordPress, Shopify or custom before quoting.

Known limits

Detection reads only the first HTML response. Technologies loaded later by JavaScript may not appear.
Sites behind aggressive bot protection may refuse the request entirely.
