## 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 Tech Stack Detector

Find out **what technologies any website runs** — e-commerce platform, CMS, JavaScript
framework, analytics, marketing/CRM tools, payment providers, CDN and web server — from just a
URL. Perfect for B2B sales targeting, competitive intelligence and lead enrichment.

Fast, single-request detection. No proxies, no login.

### Who it's for

- **B2B sales & lead-gen** — target companies by the tech they use ("everyone on Shopify",
  "sites running HubSpot").
- **Competitive intelligence** — see what competitors' sites are built with.
- **Agencies** — qualify prospects and audit stacks at scale.
- **Data enrichment** — add technographics to your CRM/lists.

### Input

| Field | Type | Description |
|-------|------|-------------|
| `urls` | array | Websites to analyze — domains or full URLs |

### Output

One row per site:

```json
{
  "url": "https://allbirds.com",
  "finalUrl": "https://www.allbirds.com/",
  "statusCode": 200,
  "status": "ok",
  "server": "cloudflare",
  "poweredBy": null,
  "technologies": [
    { "name": "Shopify", "category": "ecommerce" },
    { "name": "Google Analytics", "category": "analytics" },
    { "name": "Cloudflare", "category": "hosting" }
  ],
  "byCategory": {
    "ecommerce": ["Shopify"],
    "analytics": ["Google Analytics"],
    "hosting": ["Cloudflare"]
  }
}
```

Categories: `ecommerce`, `cms`, `framework`, `analytics`, `marketing`, `payments`, `hosting`,
`server`.

### Notes & limits

- Detection is based on the site's homepage response (headers, HTML markers, script sources,
  cookies) — a fast, single-request fingerprint covering 55+ common technologies.
- Some sites behind aggressive bot protection may return limited HTML; those come back with a
  `status` other than `ok` (e.g. `timeout`, `http_403`).
- Detection favours precision on widely-used platforms; a "not detected" technology may still
  be present but not exposed on the homepage.
- Public data; you are responsible for compliant use of the output.

# Actor input Schema

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

Websites to analyze. Domains or full URLs both work, e.g. "shopify.com", "https://www.example.com".

## Actor input object example

```json
{
  "urls": [
    "allbirds.com",
    "wordpress.org"
  ]
}
```

# 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": [
        "allbirds.com",
        "wordpress.org"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("ponderable_hydrometer/tech-stack-scraper").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);
});
