Deterministic website technology detection with structured, AI-ready JSON output.

Website Technology Detector analyzes publicly accessible websites to identify the technologies behind them using deterministic, evidence-based detection.

Instead of relying on probabilistic or black-box techniques, the Actor evaluates HTTP response headers, HTML content, JavaScript assets, metadata, and technology-specific signatures to produce structured technology intelligence.

Designed for developers, automation engineers, and AI applications, the Actor returns standardized JSON containing detected technologies, supporting evidence, confidence scores, and technology relationships. The stable output schema enables direct integration with APIs, workflow automation, CRM systems, business intelligence platforms, and AI workflows.

Why Website Technology Detector?

Understanding the technologies powering a website is valuable for automation, technical due diligence, competitive analysis, CRM enrichment, technology audits, and AI-powered applications.

Unlike traditional technology detectors that simply return a list of technologies, Website Technology Detector emphasizes explainability. Every reported technology is supported by observable evidence whenever possible, allowing downstream systems to understand not only what was detected, but also why it was detected.

The result is structured technology intelligence that is immediately consumable by both developers and software systems.

---

Input

Website Technology Detector accepts one or more website URLs and analyzes each website independently.

The simplified input schema is designed for direct integration with APIs, workflow automation platforms, scheduled tasks, and AI applications.

Input Parameters

Parameter	Type	Required	Description
urls	Array of strings	Yes	One or more website URLs to analyze.
verify_ssl	Boolean	No	Enable or disable SSL certificate verification. Default: true.

---

Example Input

{
  "urls": [
    "https://openai.com",
    "https://shopify.com",
    "https://wordpress.org"
  ],
  "verify_ssl": true
}

---

Best Practices

• Provide complete website URLs.
• HTTPS URLs are recommended.
• Analyze multiple websites in a single execution for efficient batch processing.
• Each website is processed independently.
• Invalid or unreachable websites do not interrupt processing of remaining URLs.

Output

Each analyzed website produces a standardized JSON document containing website metadata, detected technologies, and structured technology intelligence.

The output schema is designed for reliable integration with APIs, workflow automation, CRM systems, analytics platforms, and AI applications.

---

Output Structure

Each result contains three logical sections.

Website Information

Metadata describing the analyzed website, including:

• Original URL
• Resolved URL
• Processing status
• HTTP status code
• Detection timestamp
• Processing notes

Technology Categories

Detected technologies are organized into standardized categories:

• Content Management Systems (CMS)
• Ecommerce Platforms
• Frameworks
• JavaScript Libraries
• Analytics
• Advertising
• Marketing
• Payment Technologies
• Content Delivery Networks (CDN)
• Hosting & Infrastructure

Technology Intelligence

Each supported detection may include:

• Technology name
• Category
• Vendor
• Confidence score
• Supporting evidence
• Official website
• Version (when available)
• Technology relationships (when applicable)

This structured metadata enables developers and software systems to understand not only what was detected, but also why it was detected.

Example Output

[
  {
    "url": "https://nextjs.org",
    "resolvedUrl": "https://nextjs.org/",
    "status": "ok",
    "httpStatus": 200,
    "frameworks": [
      "Next.js"
    ],
    "hosting": "Vercel",
    "tech_stack": "Next.js",
    "intelligence": {
      "detections": [
        {
          "name": "Next.js",
          "category": "frameworks",
          "vendor": "Vercel",
          "confidence": 0.95,
          "evidence": "/_next/"
        }
      ],
      "relationships": [],
      "summary": "No technology relationships were identified."
    }
  }
]

Output Characteristics

Every execution provides:

• Standardized JSON output
• Consistent field names
• Machine-readable data
• Independent results for every analyzed website
• Stable schema for long-term integrations

The output is designed to be consumed directly by applications without requiring custom parsing for each detected technology.

How Detection Works

Website Technology Detector follows a deterministic, evidence-based detection pipeline designed to produce reliable and explainable technology intelligence.

Instead of relying on probabilistic or black-box techniques, the Actor evaluates publicly accessible website resources using curated technology signatures before generating a standardized JSON response.

Detection Sources

Technology detection is based exclusively on publicly accessible website resources, including:

• HTTP response headers
• HTML source code
• JavaScript assets
• Metadata
• Static resources
• URL patterns
• Infrastructure fingerprints

No authenticated resources or private APIs are required.

---

Evidence-Based Detection

Each supported technology is evaluated independently using curated detection signatures.

Whenever possible, each detection includes:

• Technology name
• Category
• Vendor
• Confidence score
• Supporting evidence
• Official website
• Version (when available)
• Technology relationships (when applicable)

This approach enables developers and software systems to understand both what was detected and why it was detected.

---

Engineering Principles

Website Technology Detector is designed around a small set of engineering principles:

• Deterministic processing
• Evidence-based detection
• Explainable results
• Stable output schema
• Modular architecture
• Backward compatibility

These principles help ensure consistent behavior across production releases while allowing the detection engine to evolve through incremental technology updates.

Limitations

Website Technology Detector analyzes only publicly accessible website resources.

Detection coverage depends on the technologies and signals exposed by the target website at the time of analysis. Browser challenges, CAPTCHA systems, authentication requirements, and intentionally hidden technologies may reduce detection coverage.

When browser challenge pages are detected, the Actor reports the challenge instead of returning potentially misleading technology detections.

Technology coverage continues to expand through curated detection signatures while maintaining backward compatibility with the published output schema.
