About the Tech Stack Checker
The Tech Stack Checker by Grab-Kit is a free online tool designed for developers, marketers, and curious web enthusiasts. Have you ever visited a beautiful website and wondered if it was built with React, Vue, or WordPress? Our tool acts as a technology detector, analyzing the HTML structure, script tags, and meta generators of any URL to reveal the underlying software powering the site.
Using the tool is incredibly straightforward. Paste the URL of the website you want to analyze into the input field and click "Detect Stack". The tool will fetch the page's source code and scan it for known fingerprints of popular frameworks (Next.js, React, Vue, Angular), CSS libraries (Tailwind, Bootstrap), CMS platforms (WordPress, Shopify), and analytics tools. It then displays the detected technologies in a clean, visual grid.
Why use Grab-Kit?
All our tools run entirely in your browser. This means your analysis is performed securely and instantly without any server-side processing. It is completely free, requires no signup, and works flawlessly on both desktop and mobile devices. Note: Some highly secured or server-rendered sites might hide their stack, but our tool detects the vast majority of public web technologies.
