## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

## Website Tech Stack Detector

Detect 40+ technologies on any website: frameworks, CMS platforms, analytics tools, CDN providers, UI libraries, payment processors, and more. Perfect for sales prospecting, competitive analysis, and market research.

### Features

- **40+ Technology Detection** — React, Vue, Angular, Next.js, Nuxt.js, Svelte, WordPress, Shopify, Wix, Squarespace, Webflow, Ghost, Drupal, Joomla, and more
- **Multi-Layer Analysis** — HTTP headers, HTML metadata, JavaScript patterns, DOM attributes
- **Fast & Reliable** — Powered by Crawlee with Playwright Chrome
- **Bulk Processing** — Analyze up to 50 websites per run
- **Detailed Results** — Technology list, server info, HTTP status, disclaimers
- **Pay-Per-Event Pricing** — $0.05 per website analyzed

### Detected Technologies

#### Frontend Frameworks & Libs
- React, Vue.js, Angular, Next.js, Nuxt.js, Svelte, jQuery, Bootstrap, Tailwind CSS

#### CMS & Website Builders
- WordPress, Shopify, Wix, Squarespace, Webflow, Ghost, Drupal, Joomla

#### E-commerce

### Input

```json
{
  "urls": [
    "https://example.com",
    "https://vercel.com",
    "https://github.com"
  ],
  "timeout": 30000
}
````

#### Input Parameters

- **urls** (array, required) — List of website URLs to analyze. Maximum 50 URLs per run. Each URL should start with `http://` or `https://`.
- **timeout** (integer, optional) — Maximum time to wait for each page to load in milliseconds. Default: 30000 (30 seconds).

### Output

```json
{
  "url": "https://vercel.com",
  "technologies": ["React", "Next.js", "Vercel", "Google Analytics"],
  "techCount": 4,
  "serverInfo": "Vercel",
  "responseStatus": 200,
  "disclaimer": "This tool detects website technologies using publicly observable signals..."
}
```

#### Output Fields

- **url** — The analyzed website URL
- **technologies** — Array of detected technology names
- **techCount** — Total number of detected technologies
- **serverInfo** — HTTP server header or x-powered-by value
- **responseStatus** — HTTP response status code
- **error** (conditional) — Error message if page failed to load
- **disclaimer** — Legal disclaimer about detection limitations

### Pricing

- **Model** — Pay-Per-Event
- **Cost** — $0.05 USD per website analyzed
- **Billing** — Only charged for successful page loads

### Example Usage

#### Basic Usage

```json
{
  "urls": ["https://example.com"]
}
```

#### Multiple URLs

```json
{
  "urls": [
    "https://github.com",
    "https://vercel.com",
    "https://notion.so",
    "https://figma.com"
  ]
}
```

#### With Custom Timeout

```json
{
  "urls": ["https://slowsite.example.com"],
  "timeout": 60000
}
```

### How It Works

1. **Page Fetch** — Uses Playwright Chrome to fetch each URL with full JavaScript rendering
2. **Content Analysis** — Extracts HTML content and HTTP response headers
3. **Pattern Matching** — Compares against 40+ technology fingerprints:
   - Script source URLs and names
   - HTML element patterns and class names
   - Meta tag contents
   - HTTP header values
4. **Result Compilation** — Returns detected technologies, server info, and metadata

### Detection Limitations

- **JavaScript Dependencies** — Some technologies may be obfuscated, lazy-loaded, or server-side only
- **False Positives/Negatives** — Detection is based on observable signals and may be incomplete
- **Dynamic Content** — Technologies loaded after page render may not be detected
- **Custom Implementations** — Custom or white-label solutions won't be detected

### Legal Disclaimer

This tool detects website technologies using publicly observable signals (HTTP headers, HTML source, JavaScript patterns). Detection results are best-effort estimates and may be incomplete or inaccurate. Some technologies may be obfuscated or server-side only.

Results are for **informational and research purposes only**. Do not use for:

- Unauthorized security testing
- Competitive espionage
- Targeting websites without consent
- Any illegal or unethical purposes

The operator makes no warranty regarding the completeness or accuracy of technology detection results. Use at your own risk and in compliance with all applicable laws and the target website's terms of service.
