## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## Website Technology Detector

Find out what any website is built with — CMS, JS frameworks, analytics, CDNs, and servers — from a single URL.

**Live on the Apify Store — run it instantly or call it as an agent tool via Apify MCP.**

### What you get

- **CMS & site builders** — WordPress, Shopify, Wix, Squarespace, Drupal, Joomla, Webflow, Ghost, HubSpot, and more.
- **JS frameworks & libraries** — React, Vue, Angular, Next.js, Nuxt, Svelte, Gatsby, jQuery, Alpine, Lodash.
- **UI frameworks** — Bootstrap, Tailwind CSS, Font Awesome.
- **Analytics & tag managers** — Google Analytics, Google Tag Manager, Facebook Pixel, Hotjar, Segment, Mixpanel, Plausible, Matomo.
- **Infra** — Cloudflare, Fastly, CloudFront, Akamai, Vercel, Netlify, GitHub Pages, Nginx, Apache, IIS, LiteSpeed, Express, PHP, ASP.NET, Rails.

Every detection comes with a **confidence score** and the exact **evidence** (HTML snippet, header, or cookie) that triggered it — no black boxes.

Detection runs purely on HTML + response-header signatures (meta generator tags, script sources, global vars, class prefixes, cookies, `Server` / `X-Powered-By` / `X-Generator` headers). Single URL or bulk, your choice.

### Input

```json
{
  "url": "https://www.cloudflare.com",
  "maxUrls": 50
}
```

Or scan many at once:

```json
{
  "urls": ["https://wordpress.org", "https://vercel.com", "https://www.shopify.com"]
}
```

### Output

One dataset item per URL:

```json
{
  "url": "https://www.cloudflare.com",
  "finalUrl": "https://www.cloudflare.com/",
  "statusCode": 200,
  "server": "cloudflare",
  "poweredBy": null,
  "technologies": [
    { "name": "Cloudflare", "category": "CDN", "confidence": 0.9, "evidence": "header server: cloudflare" },
    { "name": "Next.js", "category": "JavaScript Framework", "confidence": 0.95, "evidence": "html: /_next/static/" },
    { "name": "React", "category": "JavaScript Framework", "confidence": 0.8, "evidence": "html: data-reactroot" }
  ]
}
```

# Actor input Schema

## `url` (type: `string`):

A single website URL to scan for its tech stack.

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

Multiple website URLs to scan in one run.

## `maxUrls` (type: `integer`):

Safety cap on how many URLs to process.

## Actor input object example

```json
{
  "url": "https://www.cloudflare.com",
  "maxUrls": 50
}
```

# 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 = {
    "url": "https://www.cloudflare.com"
};

// Run the Actor and wait for it to finish
const run = await client.actor("eliai/webpage-tech-detector").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();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "url": "https://www.cloudflare.com" }

# Run the Actor and wait for it to finish
run = client.actor("eliai/webpage-tech-detector").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print("💾 Check your data here: https://console.apify.com/storage/datasets/" + run["defaultDatasetId"])
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)
