StackScope uses advanced detection techniques to identify technologies with high accuracy:
| Method | Description | Example |
|---|---|---|
| JavaScript Globals | Checks window object for framework variables |
window.React, window.Vue |
| Script Analysis | Examines <script src> attributes |
CDN URLs, framework files |
| Meta Tags | Inspects meta tag content | <meta name="generator"> |
| Cookie Detection | Checks technology-specific cookies | _ga (Google Analytics) |
| HTML Patterns | Safe regex matching on page content | data-reactroot, ng-app |
| DOM Monitoring | Observes dynamic content changes | SPA framework detection |
- 90-100%: High confidence - Multiple detection methods confirm
- 70-89%: Medium confidence - Strong indicators present
- 50-69%: Low confidence - Some indicators but inconclusive
- <50%: Very low - Minimal evidence, likely false positive
StackScope maintains an extensive fingerprint database with 2,390+ technologies:
- Version Detection - Identifies specific framework/library versions
