TechReveal - Web Technology Profiler

100% Free alternative to Wappalyzer and BuiltWith. Discover web technologies, frameworks, and CMS instantly.

TechReveal is a 100% free tool to see exactly what technologies a website is built with. Think of it as a faster, lightweight alternative to Wappalyzer and BuiltWith. It does the basics—detecting frameworks (like React or Vue), CMS, and web servers—but it also includes a few unique features for developers and security researchers: • Evidence Mode: Click on any detected technology to see the exact line of code, HTTP header, or variable that triggered the detection. No more guessing. • Leak Radar: Automatically alerts you if a website is leaking sensitive structural data or Source Maps (like exposed Next.js hydration data). • Architecture Map: See the website's tech stack visualized as a node map instead of a plain text list. • Deep Scan: Monitors the page as you scroll to catch lazy-loaded technologies that other extensions miss. TechReveal runs entirely locally in your browser. It doesn't track you, it has no premium paywalls, and it clears its own cache so it won't slow down your computer. Just install it and start exploring.
