Frequently Asked Questions

What is a tech stack detector?▾
A tech stack detector analyzes a website's publicly visible code, HTTP headers, and script URLs to identify what technologies power it — including the CMS, analytics platform, JavaScript framework, CDN, and marketing tools.
How does this tool differ from Wappalyzer or BuiltWith?▾
Wappalyzer's free browser extension limits results to 5 technologies and requires installation. BuiltWith costs $295+/month for full reports. Our tool provides unlimited free scans directly in your browser with no account required.
What does the Privacy Score measure?▾
The Privacy Score reflects how many high-risk data collectors (GA4, Meta Pixel, TikTok, etc.) are embedded on the site. Sites with cookieless or self-hosted analytics score higher. The score is from 0–100 (A–F).
Can this tool detect all technologies?▾
It detects technologies with visible signatures in the HTML source or HTTP headers — which covers most publicly available tools. Server-side technologies without a client-side footprint (e.g., internal databases) cannot be detected this way.
Why do I see outdated technologies on my competitor's site?▾
Many sites continue running deprecated tools (e.g., Universal Analytics after July 2023) because they were never cleaned up. Our tool flags these with a "legacy" notice so you can identify technical debt.
Is this legal? Can I scan competitor websites?▾
Yes. This tool only reads publicly accessible HTML — the same content any browser downloads when visiting the site. No authentication, crawling, or scraping beyond a single page fetch is performed.
How often are the technology signatures updated?▾
Technology patterns are updated regularly to reflect new framework versions, CDN URLs, and analytics script changes. The database covers 50+ technologies across 8 categories.
