## 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

## Website Tech Stack Detector

Find out what any website is built with - no API key required. Pass a list of domains and get one clean row per site with the CMS, ecommerce platform, JavaScript framework, analytics, payment, and marketing tools it uses, plus its CDN, web server, email provider, and DNS records.

### What you get

- **Technologies by category** - CMS, ecommerce, JavaScript framework, analytics, tag manager, marketing, payments, fonts, CDN, hosting, and web server
- **`technologiesFlat`** - a single de-duplicated list of every detected technology
- **Server & X-Powered-By** headers
- **CDN / hosting** - Cloudflare, Fastly, Akamai, CloudFront, Vercel, Netlify, and more
- **Email provider** - inferred from MX records (Google Workspace, Microsoft 365, Zoho, Proton, Proofpoint, etc.)
- **DNS records** - A records (with primary IP), MX records, and name servers (NS)
- **Page title** and final URL after redirects

### Use cases

- **Lead qualification & enrichment** - score prospects by the tools they run (e.g. find every Shopify or HubSpot site in a list)
- **Competitive intelligence** - see which analytics, payment, and marketing stack competitors use
- **Sales prospecting** - build target lists of sites running a specific platform you integrate with
- **Tech due diligence** - quick technology snapshot for a portfolio of domains
- **Email-provider segmentation** - split a domain list by Google Workspace vs Microsoft 365

### How to use

1. Paste one or more **domains** (e.g. `apify.com`) or full URLs
2. Optionally set **Max Items** to cap how many domains are analyzed (`0` = all)
3. Run the actor - results land in the **Dataset** tab
4. Export to JSON, CSV, Excel, or Google Sheets directly from the Apify console

#### Example input

```json
{
  "domains": ["apify.com", "shopify.com", "vercel.com"],
  "maxItems": 0
}
```

### Output format

One dataset record per domain:

```json
{
  "input": "shopify.com",
  "domain": "shopify.com",
  "finalUrl": "https://www.shopify.com/",
  "statusCode": 200,
  "ipAddress": "23.227.38.74",
  "server": "cloudflare",
  "poweredBy": null,
  "cdn": "Cloudflare",
  "emailProvider": "Google Workspace",
  "technologies": {
    "JavaScript Framework": ["React"],
    "Analytics": ["Google Analytics", "Segment"],
    "CDN": ["Cloudflare"]
  },
  "technologiesFlat": ["Cloudflare", "Google Analytics", "React", "Segment"],
  "mxRecords": ["aspmx.l.google.com"],
  "nsRecords": ["ns1.dnsimple.com"],
  "aRecords": ["23.227.38.74"],
  "title": "Shopify - The all-in-one commerce platform",
  "error": null
}
```

### Notes

- Detection is based on homepage HTML, response headers, and DNS - it reflects what's visible on the landing page. Tools loaded only on inner pages or after consent may not appear.
- `error` is populated when a site can't be fetched (timeout, block, or non-2xx); DNS fields may still be filled in those cases.

# Actor input Schema

## `domains` (type: `array`):

Domains or full URLs to analyze, e.g. 'apify.com' or 'https://www.shopify.com'. One row per domain is pushed to the dataset.

## `maxItems` (type: `integer`):

Maximum number of domains to analyze. 0 = analyze all domains in the list.

## Actor input object example

```json
{
  "domains": [
    "apify.com",
    "shopify.com"
  ],
  "maxItems": 0
}
```

# Actor output Schema

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

Each record: { input, domain, finalUrl, statusCode, ipAddress, server, poweredBy, cdn, emailProvider, technologies, technologiesFlat, mxRecords, nsRecords, aRecords, title, error }

# 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 = {
    "domains": [
        "apify.com",
        "shopify.com"
    ],
    "maxItems": 0
};

// Run the Actor and wait for it to finish
const run = await client.actor("seemuapps/website-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 = {
    "domains": [
        "apify.com",
        "shopify.com",
    ],
    "maxItems": 0,
}

# Run the Actor and wait for it to finish
run = client.actor("seemuapps/website-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 '{
  "domains": [
    "apify.com",
    "shopify.com"
  ],
  "maxItems": 0
}' |
apify call seemuapps/website-tech-stack-detector --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,seemuapps/website-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).
