Tech Stack Detector: CMS, Shop, Analytics, Hosting & Email

Find out which technologies any website uses, for one site or ten thousand. Enter domains or URLs and get one clean, CSV-ready row per website with the CMS, shop system, analytics, ad pixels, cookie consent tool, CDN, hosting and email provider, including versions where the site reveals them.

• 3,500+ technologies recognised from HTML, script sources, meta tags, HTTP headers, cookies, page elements and public DNS records (MX/TXT/NS/SOA). DNS reveals what a page never shows, e.g. Google Workspace or Microsoft 365 for email.
• Flat columns per category (cms, ecommerce, analytics, consent, cdn, hosting, emailProviders …) that are ready for filtering in Excel or your CRM, plus a detailed list with version, confidence and categories.
• Fast and cheap: no browser needed. Most sites take about a second.
• Fair billing: sites that cannot be loaded or block the request are free. You can set a maximum cost per run; the Actor stops cleanly when it is reached.

How it works and limits

The Actor loads each page like a browser would request it, but without running JavaScript. This keeps it fast and inexpensive. Technologies that only appear after JavaScript runs, or only on sub-pages, can be missed; tools that are referenced in the HTML (script tags, meta tags, page elements, headers, cookies) are found reliably. Sites behind strict bot protection may answer with HTTP 403; such rows are marked and not charged, and header/DNS based findings (e.g. Cloudflare, email provider) are still included.

Fingerprints are based on the open-source Wappalyzer data (MIT-licensed release 6.10.54). Technologies launched after early 2023 may not be recognised yet.

FAQ

Is this legal? The Actor only requests the public page you enter (one request per site, like a visitor) and reads public DNS records. It does not log in, does not bypass protections and stores no personal data.

Why is a technology I know missing? Most likely it is loaded by JavaScript after the page starts, or only used on other pages. Enter that page's URL directly to analyze it.

Something wrong or missing? Open an issue on the Actor page. We usually answer within one business day and fix confirmed bugs quickly.
