Web Technology Detector API

WebTech Detector is a lightweight and developer-friendly API built with NestJS that detects technologies used on websites. It analyzes HTTP headers, HTML meta tags, and embedded scripts to identify common CMSs (like WordPress, Joomla), backend frameworks (Laravel, Django), frontend libraries (React, Vue, Angular), analytics tools, hosting providers (Netlify, Vercel), and web servers (Apache, Nginx, LiteSpeed, IIS).

Ideal for SEO tools, competitive intelligence, browser extensions, and audits.

• Backend frameworks (Laravel, Django, Rails, ASP.NET)
• Frontend frameworks (React, Angular, Vue, Svelte, Next.js)
