Performance & Tech tool
Detect the technology stack of any website including CMS (WordPress, Shopify), frameworks (React, Next.js), analytics tools, CDNs, hosting providers, and more using Wappalyzer-style fingerprinting.
What it checks
Identify technologies, frameworks, and CMS used by a website.
Inspect protocol, CDN, compression, and response signals where available.
Surface page weight, resource count, app shell clues, or installability signals.
Prioritize fixes that reduce latency, transfer size, or rendering friction.
Methodology
Next steps
Interpretation
Use cases
Find infrastructure or payload issues that can affect LCP, CLS, and INP.
Understand how a site is built, delivered, and optimized at the edge.
Retest after releases to catch heavier pages, slower responses, or missing compression.

Frequently asked questions
No. Enter a URL or domain and run the check in your browser. Some results can be partial if the target site blocks requests or hides the data being checked.
The Tech Stack Detector runs live checks against the target website. Results reflect what was reachable at the time of the test, so retest after changing DNS, redirects, headers, or page content.
We analyze HTTP headers, HTML meta tags, JavaScript globals, cookie names, and page patterns to fingerprint frameworks, CMS platforms, analytics tools, and hosting providers.
Yes. The detector looks for Cloudflare, Fastly, AWS CloudFront, Akamai, and other CDN clues from response headers and DNS patterns.
It answers a similar first question: what public technology clues are visible on this domain? BuiltWith and Wappalyzer are stronger for large datasets, history, enrichment, and prospecting workflows.
