Technology Stack Checker (Full-Stack Website Architecture Audit)
Analyze frontend frameworks, backend engines, web servers, databases, and hosting infrastructure.
TL;DR: Technology Stack Checker audits the complete technology stack of any website, detailing frontend, backend, CDN, and analytics layers.
What Is a Full Technology Stack Audit and How Does It Work?
A Technology Stack Audit inspects the multi-tiered architecture of a web application across four core layers: Frontend (HTML5, CSS frameworks, JavaScript libraries), Backend/Server (Node.js, PHP, Python, Nginx, Apache), Infrastructure (Cloudflare, AWS, Vercel, Netlify), and Third-Party Integrations (Stripe, Google Analytics, Intercom).
How to Use the Technology Stack Checker
Our Technology Stack Checker is engineered for rapid developer workflow, high-performance in-browser execution, and complete code privacy.
- Enter a website domain URL or paste raw HTML source code.
- Click 'Audit Tech Stack' to trigger comprehensive multi-layer inspection.
- Review the architectural tier breakdown: Client-Side, Server/Hosting, Analytics & Marketing.
- Examine detected security headers, HTTP versions (HTTP/2, HTTP/3), and TLS configurations.
- Export the full architecture audit report.
Key Capabilities & Developer Best Practices
- Fast In-Browser Processing: Zero server latency; code formatting, validation, and transformations execute in real time.
- Complete Data Confidentiality: Work with sensitive API keys, production configs, and database records safely on your local device.
- Standards-Compliant Output: Generates clean, RFC-compliant code ready for production deployment and clean Git diffs.
Safe & Transparent URL Inspection
All network queries only inspect public, non-authenticated headers and HTML assets. When analyzing pasted source code, processing runs 100% locally in your web browser with complete confidentiality.
Frequently Asked Questions
- A technology stack checker is a developer diagnostic tool that performs a comprehensive audit of all software layers, frameworks, and infrastructure powering a website.
- It audits four distinct tiers: 1. Frontend UI (React, Vue, Tailwind CSS), 2. Web Server & CMS (WordPress, Nginx, Apache), 3. CDN & Hosting (Cloudflare, Vercel, AWS), and 4. Third-Party Services (Stripe, Segment, GA4).
- It analyzes HTTP response headers (`X-Powered-By`, `Server`), cookie session names (e.g. `PHPSESSID`, `JSESSIONID`, `connect.sid`), and URL routing structures.
- Yes. Hosting providers are identified via server response headers, DNS CDN signatures, and edge proxy identifiers.
- Use the 'Paste Store HTML' mode to paste the page's HTML source directly for client-side evaluation.
- Yes. It only inspects public, non-authenticated web assets and headers that any web browser receives when visiting a page.
- Yes. Click 'Export Report' to save the complete full-stack inventory in Markdown or CSV format.
- Yes. NexLove's Technology Stack Checker is 100% free with unlimited domain lookups.
