Practical Use Cases

Tech stack analysis helps engineers in the following situations:

1. Competitive Research

Quickly answer questions like 'What makes this site so fast?' or 'What CMS do competitors use?' Use findings as reference data for your own technology decisions.

2. Learning & Skill Development

Discover what technologies power successful websites to identify trends and decide what to learn next. Valuable for making practical technology choices in your work.

3. Migration Planning

When planning site renewals or system migrations, accurately understand current technology stack to evaluate migration costs and compatibility in advance.

4. Security Audit

Verify that managed sites aren't using outdated software versions or check for unintended technology inclusion.

Frequently Asked Questions (FAQ)

What technologies can be detected?

We detect CMS (WordPress, Wix, Shopify, etc.), JavaScript frameworks (React, Vue, Angular, etc.), server software (Nginx, Apache), analytics tools (Google Analytics, etc.), CDN, and UI libraries (jQuery, Bootstrap, etc.).

How accurate is the detection?

Detection is based on HTTP headers, HTML source code, and JavaScript file pattern matching. Accuracy is high for common technologies, but heavily customized sites or those actively hiding their tech stack may not be fully detected.

Is analysis data stored?

No, analysis results are not stored on our servers. Analysis is performed in real-time and deleted after being displayed in your browser.

Can any website be analyzed?

Yes, any publicly accessible website can be analyzed. However, sites with access restrictions (authentication required) or those blocking robot access cannot be analyzed.

Can version information be obtained?

For some technologies, version information can be obtained. WordPress, PHP, jQuery, etc. can show versions if included in source code or headers.

Is this tool legal?

Yes, it's completely legal. We only read publicly available website information, similar to what a browser does. We don't perform any operations that would burden the target site.

Can I use this for competitive analysis?

Yes, this tool is perfect for analyzing competitors' technology stacks. You can quickly identify which CMS, frameworks, and analytics tools they use. This information helps inform your own technology decisions and understand industry trends.

Why is React or Vue.js sometimes not detected?

Highly optimized sites may have framework code minified and obfuscated during the build process, making detection difficult. Additionally, sites using Server Side Rendering (SSR) may have minimal framework traces in the initial HTML, reducing detection accuracy.
