## Pricing

from $0.47 / 1,000 url analyzeds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

## Website Tech Stack Analyzer

Detect the CMS, frameworks, and analytics any website uses -- without needing access or credentials. Whether you are profiling competitors, qualifying leads by platform, or auditing a migration target, bulk technology detection saves hours of manual inspection. Feed in hundreds of URLs and get structured results back in seconds via API or the Apify Console.

### Features

- **CMS detection** — identifies WordPress, Shopify, Webflow, Ghost, Joomla, Drupal, and Magento from HTML footprints and meta tags
- **Framework fingerprinting** — detects React, Next.js, Gatsby, Vue.js, Nuxt.js, Angular, and Express via DOM markers and headers
- **Server identification** — reads `Server` and `X-Powered-By` headers to surface Nginx, Apache, Cloudflare, Vercel, and PHP
- **Analytics tracking** — flags Google Analytics, Facebook Pixel, and Hotjar presence
- **Bulk processing** — scan hundreds of URLs in a single run with configurable concurrency
- **Structured output** — results are grouped into `cms`, `frameworks`, `server`, `analytics`, and a combined `technologies` array
- **Pay-per-event billing** — you only pay for each URL analyzed, with automatic charge-limit enforcement

### Input

| Field | Type | Required | Default | Description |
|-------|------|----------|---------|-------------|
| `urls` | `array` | Yes | — | List of URLs to analyze. Each URL is fetched and scanned for technology fingerprints. |
| `timeoutSeconds` | `integer` | No | `15` | Maximum seconds to wait for each URL response before timing out. |
| `concurrency` | `integer` | No | `10` | Number of URLs to process in parallel. Increase for large batches, decrease if you hit rate limits. |

#### Input Example

```json
{
  "urls": [
    "https://crawlee.dev",
    "https://shopify.com",
    "https://wordpress.org"
  ],
  "timeoutSeconds": 15,
  "concurrency": 10
}
```

### Output

Each URL produces one dataset item containing categorized technology arrays and metadata about the request.

- `inputUrl` (`string`) — the URL you submitted
- `finalUrl` (`string`) — the URL after redirects
- `status` (`number`) — HTTP status code
- `cms` (`string[]`) — detected content management systems
- `frameworks` (`string[]`) — detected frontend/backend frameworks
- `server` (`string[]`) — detected server software and hosting platforms
- `analytics` (`string[]`) — detected analytics and tracking tools
- `technologies` (`string[]`) — combined list of all detected technologies
- `error` (`string | null`) — error message if the URL could not be fetched

#### Output Example

```json
{
  "inputUrl": "https://crawlee.dev",
  "finalUrl": "https://crawlee.dev/",
  "status": 200,
  "cms": [],
  "frameworks": ["Next.js", "React"],
  "server": ["Vercel"],
  "analytics": ["Google Analytics"],
  "technologies": ["Next.js", "React", "Vercel", "Google Analytics"]
}
```

### Pricing

| Event | Cost |
|-------|------|
| URL Analyzed | Pay-per-event (see actor pricing page) |

The actor stops automatically when the per-run charge limit is reached, so you never overspend.

### Use Cases

- **Competitive intelligence** — profile hundreds of competitor sites to understand their tech choices and identify trends
- **Lead qualification** — filter prospects by platform (e.g., find all Shopify stores or WordPress sites in a list)
- **Migration audits** — inventory the current tech stack before a replatforming project
- **Market research** — map technology adoption across an industry vertical at scale
- **Agency prospecting** — identify sites running outdated CMS versions as potential service leads
- **Security reconnaissance** — detect exposed server headers and framework versions for vulnerability assessment

# Actor input Schema

## `urls` (type: `array`):

List of website URLs to analyze. Each URL is fetched and scanned for CMS, framework, server, and analytics fingerprints.

## `timeoutSeconds` (type: `integer`):

Maximum seconds to wait for each URL response. Increase for slow or geographically distant sites.

## `concurrency` (type: `integer`):

Number of URLs to process in parallel. Higher values speed up large batches but may trigger rate limits on some hosts.

## Actor input object example

```json
{
  "urls": [
    "https://crawlee.dev"
  ],
  "timeoutSeconds": 15,
  "concurrency": 10
}

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "urls": [
        "https://crawlee.dev"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("andok/tech-stack-analyzer").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();

## CLI example

```bash
echo '{
  "urls": [
    "https://crawlee.dev"
  ]
}' |
apify call andok/tech-stack-analyzer --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,andok/tech-stack-analyzer"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
