Detected JavaScript Libraries
Discover the JavaScript Technologies Behind Any Website
Our JavaScript Library Finder is a powerful tool that helps developers, designers, and curious users identify which JavaScript frameworks and libraries are used on any website. Whether you're conducting competitive research, learning from other developers, or simply satisfying your curiosity, this tool provides valuable insights into a website's technical stack.
How to Use the JavaScript Library Detector
Using our tool is simple:
- Option 1: Enter the website URL in the input field above. Our tool will fetch the HTML content and analyze it for JavaScript libraries.
- Option 2: If you already have the HTML code, paste it directly into the text area for immediate analysis.
Within seconds, you'll see a list of all detected JavaScript frameworks, libraries, and plugins used on the website.
Why Identify JavaScript Libraries?
Knowing which JavaScript technologies a website uses can be valuable for several reasons:
- Learning from others: Discover what frameworks successful websites use in production.
- Competitive analysis: Understand the technical stack of competitors.
- Troubleshooting: Identify potential conflicts when integrating with other sites.
- Career development: Learn which JavaScript skills are most in demand.
Common JavaScript Libraries We Detect
Our tool can identify hundreds of popular JavaScript libraries including:
- Frameworks: React, Angular, Vue.js, Svelte, Ember
- UI Libraries: jQuery, Bootstrap, Foundation, Material UI
- Charting Libraries: Chart.js, D3.js, Highcharts
- Animation Libraries: GSAP, Anime.js, Three.js

How Our JavaScript Detection Works
The tool analyzes several indicators to detect JavaScript libraries:
- Script source URLs containing library names
- Global variables exposed by libraries
- Characteristic CSS class names
- Library-specific meta tags
- Known patterns in the code structure
While our detector is highly accurate, some minified or customized implementations may not be detected. For best results, try analyzing both the homepage and inner pages of a website.
