## 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`).

# README

## Tech Stack Detector — Cheap Wappalyzer & BuiltWith Alternative

Paste a list of websites. For each one you get the technologies it runs on, grouped by category, with versions where the site shows them.
**One flat price per website** — not per technology found.

### What it detects (190 technologies, 31 categories)

| Category | Examples |
|---|---|
| CMS | WordPress (with version), Joomla, Drupal, TYPO3, Contao, Ghost, HubSpot CMS, Contentful, Storyblok |
| Website builders | Wix, Squarespace, Webflow, Jimdo, Framer, Duda, IONOS, STRATO, GoDaddy, Site123, Hostinger |
| E-commerce | Shopify, WooCommerce, Magento, Shopware, PrestaShop, BigCommerce, JTL, Gambio, plentymarkets |
| JavaScript | React, Next.js, Vue, Nuxt, Angular, Svelte, Astro, Gatsby, jQuery (with version), Alpine.js, htmx |
| Page builders & plugins | Elementor, Divi, WPBakery, Bricks, Yoast SEO, Rank Math, WPML, WP Rocket |
| Analytics & ads | Google Analytics, GTM, Matomo, Plausible, Hotjar, Clarity, Meta Pixel, Google Ads, TikTok, LinkedIn |
| Consent, chat, booking | Cookiebot, Usercentrics, OneTrust, Borlabs · Intercom, Tawk.to, HubSpot, WhatsApp · Calendly, Doctolib, Treatwell, OpenTable |
| Payments & reviews | Stripe, PayPal, Klarna, Mollie, Adyen · Trustpilot, Trusted Shops, ProvenExpert |
| Infrastructure | Cloudflare, Fastly, CloudFront, Akamai, Vercel, Netlify, nginx, Apache, LiteSpeed, PHP, ASP.NET |
| Legacy | Flash, Adobe Muse, FrontPage, Dreamweaver templates — perfect for finding sites that need a rebuild |

Strong European coverage (IONOS, STRATO, JTL, Gambio, Shopware, Contao, Borlabs, etracker, Doctolib, Treatwell) that US tools often miss.

### Input

```json
{ "websites": ["example.com", "https://shop.example.de"], "includeEvidence": false }
```

### Output (one row per website)

```json
{
  "domain": "vercel.com",
  "status": "OK",
  "technologyCount": 3,
  "categories": { "Hosting": ["Vercel"], "JavaScript framework": ["Next.js", "React"] },
  "technologies": [ { "name": "Next.js", "category": "JavaScript framework", "version": null } ]
}
```

`status` is `OK`, `BLOCKED` (site blocks automated visitors — results may be incomplete) or `UNREACHABLE`.
Turn on `includeEvidence` to see exactly which header, script or tag triggered each match.

### How it works

One normal page load per site (https and http, with and without `www`). It reads the HTML, script and link URLs,
meta tags, response headers and cookie names. No logins, no crawling of private areas. Technologies that only load
after user interaction may not be visible.

### Use with AI agents

Works through the Apify MCP server: an agent passes domains and gets structured technology lists back —
e.g. "find Shopify stores", "which of these leads use WordPress", "who still runs Flash".

### Pricing

Pay per result: one flat price per website analysed. No subscription.

# Actor input Schema

## `websites` (type: `array`):

Domains or URLs to analyse, one per line. Example: shopify.com

## `includeEvidence` (type: `boolean`):

Add the matched snippet (header, script, meta tag) for every technology.

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

How many websites are analysed at the same time.

## `maxWebsites` (type: `integer`):

Stop after this many websites (leave empty for all).

## Actor input object example

```json
{
  "websites": [
    "wordpress.org",
    "shopify.com",
    "vercel.com"
  ],
  "includeEvidence": false,
  "concurrency": 15
}
```

# Actor output Schema

## `results` (type: `string`):

One row per website: status, technology count, technologies grouped by category, full technology list with category and version.

# 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 = {
    "websites": [
        "wordpress.org",
        "shopify.com",
        "vercel.com"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("nightshift/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) => {
    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 = { "websites": [
        "wordpress.org",
        "shopify.com",
        "vercel.com",
    ] }

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

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

## CLI example

```bash
echo '{
  "websites": [
    "wordpress.org",
    "shopify.com",
    "vercel.com"
  ]
}' |
apify call nightshift/tech-stack-detector --silent --output-dataset

```

## MCP server setup

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

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).
