Getting Started

The Tech Stack Detector analyzes websites to identify the technologies they use, including frameworks, content management systems, hosting platforms, analytics tools, and more. It provides confidence scores for each detected technology and offers performance and security insights.

Quick Start Steps:

  1. Enter a website URL in the input field (include https:// or http://)
  2. Click "Analyze" to start the analysis
  3. Wait for the analysis to complete (progress is shown during analysis)
  4. View results in the Overview, Detailed, or Security tabs
  5. Use History to revisit previous analyses or compare multiple websites

Tip: Use the Dashboard link to access additional analytics and insights about your analysis history.

Single URL Analysis

The primary feature allows you to analyze any website by entering its URL. The tool will fetch and analyze the website to detect its technology stack.

Analysis Input

URL Format

Enter a complete URL including the protocol (http:// or https://)

https://example.com

Note: Some websites may block automated requests or require specific headers. If analysis fails, try a different URL or check if the website is accessible.

Analysis Progress

During analysis, a progress bar shows the current status. The analysis includes:

  • Fetching website content and resources
  • Analyzing HTML, CSS, and JavaScript
  • Detecting frameworks, libraries, and tools
  • Checking security headers and HTTPS
  • Measuring performance metrics

Batch Analysis

Analyze multiple websites at once using the batch analysis feature. This is useful for comparing competitors, auditing multiple sites, or building a technology database.

How to Use Batch Analysis

  1. Click the "Batch Analysis" button
  2. Enter multiple URLs, one per line
  3. Click "Analyze" to start processing
  4. Results are added to your history for each URL

Example Input:

https://example1.com
https://example2.com
https://example3.com

Tip: Batch analysis processes URLs sequentially. For large batches, the analysis may take several minutes. Results are saved to your history automatically.

Results Overview

The Overview tab displays detected technologies organized by category. Each category shows the top technologies with their confidence scores.

Performance Metrics

Shows load time in milliseconds and page size in kilobytes. These metrics help assess the website's performance characteristics.

Technology Categories

Technologies are grouped by category: Frameworks, CMS, Hosting, Analytics, Marketing, and more. Each category displays the top 3 detected technologies.

Detected Categories:

Frameworks

React, Vue, Angular, Next.js, Nuxt, etc.

CMS

WordPress, Shopify, Wix, Ghost, etc.

Hosting

Vercel, Netlify, AWS, Cloudflare, etc.

Analytics

Google Analytics, Mixpanel, Hotjar, etc.

Detailed Analysis

The Detailed tab provides comprehensive information about each detected technology, including version information, descriptions, and links to official websites.

Technology Details Include:

Name

The exact name of the detected technology

Version

Detected version number when available

Confidence

Percentage indicating detection certainty

Description

Brief description of the technology

Website

Link to the official technology website

Confidence Score: Technologies are detected with varying confidence levels. Higher confidence indicates stronger evidence from HTML patterns, JavaScript files, and resource headers.

Security Analysis

The Security tab provides insights into the website's security configuration, including HTTPS status and security headers.

HTTPS Status

Indicates whether the website uses HTTPS encryption. A secure connection is shown with a green badge, while insecure connections are marked with a red badge.

Security Headers

Lists detected security headers such as Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.

Common Security Headers:

Content-Security-Policy
Strict-Transport-Security
X-Frame-Options
X-Content-Type-Options
Referrer-Policy
Permissions-Policy

Warning: Websites without HTTPS may expose user data to interception. Security headers help protect against common attacks like XSS and clickjacking.

History Management

All analyses are saved to your history, allowing you to revisit previous results, search through analyses, and filter by category.

History Features

Search

Search through history by URL, title, or technology name

Filter by Category

Filter results to show only analyses containing specific technology categories

Starred Items

Mark important analyses with a star for quick access

Delete

Remove unwanted analyses from history

Tip: Use the History panel to track changes in a website's tech stack over time by re-analyzing and comparing results.

Website Comparison

Compare multiple websites side-by-side to analyze their technology stacks, performance metrics, and detect patterns or differences.

How to Compare Websites

  1. Open the History panel to view all previous analyses
  2. Select 2 or more websites using the checkboxes
  3. Click "Compare" to open the comparison view
  4. View side-by-side comparison of metrics and technologies

Comparison Includes:

Load Time
Compare page speed
Page Size
Compare resource size
Technologies
Compare tech stacks

Export Options

Export analysis results for external use, reporting, or integration with other tools. Two formats are supported: JSON and CSV.

JSON Export

Exports complete analysis data including all detected technologies, performance metrics, and security information.
