## 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.

### What you get

| Field | Description |
|-------|-------------|
| `url` / `finalUrl` | Requested URL and the URL after redirects |
| `statusCode` | HTTP status |
| `title` / `description` | Page title and meta description |
| `technologies` | Array of `{ name, category, evidence }` |
| `technologyCount` | How many technologies were detected |
| `byCategory` | Technologies grouped by category |
| `cms` / `ecommerce` | Primary CMS and ecommerce platform |
| `frameworks`, `analytics`, `advertising`, `payments`, `liveChat`, `cdn`, `hosting` | Ready-to-use lists |
| `server` / `poweredBy` / `generator` | Raw server fingerprints |

### Input

```json
{
  "urls": ["https://www.shopify.com", "https://vercel.com"],
  "maxItems": 100
}
```

### Use cases

- **Lead generation**: find every site running Shopify, WordPress or Stripe and pitch them
- **Competitive research**: see what your competitors' stacks look like
- **Sales prospecting**: qualify accounts by the tools they already pay for
- **Market sizing**: measure platform adoption across a list of domains
- **Security and compliance**: audit which third-party scripts a site loads

### Notes

- Detection is based on real page signals: HTML markers, script URLs, response headers and cookies. Each finding includes the `evidence` that triggered it.
- Sites that block automated requests may return a non-200 status. Those runs are not charged.

# 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://www.shopify.com"
    ],
    "maxItems": 100,
    "proxyConfiguration": {
        "useApifyProxy": true
    }
};

// Run the Actor and wait for it to finish
const run = await client.actor("gio21/tech-stack-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) => {
