Tech stack checker — frameworks, hosting, infrastructure, and security
Go beyond CMS detection. TrueTechFinder identifies frontend frameworks, build tools, hosting providers, CDN configuration, backend signals, and security headers — with a Stack Health Score and JSON export for every scan.
What signals we analyse — and how
Every tech stack detection involves multiple layers of signal analysis. Here is what TrueTechFinder examines for each scan, and the detection method used per category.
React, Vue.js, Angular, Next.js, Nuxt, Svelte, Astro, Remix
JavaScript bundle signatures, global variables, data attributes
Webpack, Vite, Turbopack, Parcel, Rollup, esbuild
Bundle filename patterns, asset hash formats, source map headers
Vercel, Netlify, AWS, GCP, Cloudflare Pages, Fly.io, Railway
Server headers, IP ranges, DNS records, edge node signatures
Cloudflare, Fastly, Akamai, CloudFront, Sucuri
CF-Ray headers, Fastly-IO headers, server identification
Node.js, PHP, Python, Ruby, Java, .NET
X-Powered-By headers, error page signatures, framework-specific cookies
HSTS, CSP, reCAPTCHA, Cloudflare protection, SSL/TLS grade
HTTP security headers, meta tag policies, challenge page detection
Structured data, not just a visual report
Every scan result is exportable as structured JSON. The data is organised by technology category — CMS, hosting, frontend, analytics, CDN, security, build tools — ready for use in your own pipelines, dashboards, or reports.
The Stack Health Score is included in every API response and JSON export. Use it programmatically to flag sites with low scores, track stack health over time, or trigger alerts when a monitored site's score drops.
A REST API is in active development. It will support single URL scans, batch scanning, and webhook delivery of results. Designed for integration with CI/CD pipelines, monitoring tools, and custom dashboards.

Common questions from developers
A tech stack checker analyses a website's HTTP responses, JavaScript bundles, HTML markup, and network signatures to identify the technologies it is built on — including the frontend framework, CMS, hosting provider, CDN, analytics tools, and security configuration.
TrueTechFinder inspects HTTP response headers (X-Powered-By, Server, Via, CF-Ray, etc.), cookie names, redirect patterns, and DNS records. These signals often reveal hosting providers, backend frameworks, and CDN configuration that client-side tools miss.
Yes. Every scan result includes a JSON export option that gives you the structured technology data — categorised by CMS, hosting, frontend, analytics, CDN, security, and more. Useful for integrating scan data into your own tools or reports.
An API is in development and will be released soon. It will allow you to programmatically scan websites and retrieve structured technology data, Stack Health Scores, and AI insights. Sign up to be notified when it launches.
The Stack Health Score (0–100) evaluates the overall technical quality of a detected stack. It weights factors including framework modernity, security header presence (HSTS, CSP), CDN usage, dependency staleness signals, and observable risk patterns. A score above 70 indicates a healthy, modern stack. Below 40 suggests meaningful technical debt or security gaps.
The detection engine is updated continuously as new technologies are released and new fingerprinting methods are developed. If you find a technology that is not being detected, you can report it and it will be prioritised for the next database update.
