## 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 & Contact Enricher

**The BuiltWith / Wappalyzer alternative without the subscription fees.**

Stop paying $295+/month for tech lookups you'll run a few thousand times a year. This Actor scans any list of company domains and returns their technology stack, key contact signals, and social profiles — in a clean, ready-to-export dataset. Pay per run, not per month.

### Why sales, RevOps, and growth teams use this

- **Kill your BuiltWith / Wappalyzer subscription.** Get the same signal — CMS, analytics, CRM, payments, CDN — without a recurring license.
- **Qualify leads at a glance.** Instantly see if a prospect runs Shopify vs. Magento, HubSpot vs. Marketo, or Stripe vs. Adyen — and pitch accordingly.
- **Skip-trace contact info for free.** Pulls the public contact email and social profiles (LinkedIn, Twitter/X, GitHub, Facebook) straight off the site — no separate enrichment tool required.
- **Built for scale.** Fully async with configurable concurrency — profile hundreds of domains in the time a browser-based tool takes to load one.
- **Zero maintenance.** No browser, no proxies, no flaky headless Chrome — just fast HTTP requests and battle-tested signature matching.

### What it detects

| Category | Technologies |
|---|---|
| CMS & E-commerce | Shopify, WordPress, Webflow, Magento, BigCommerce, Squarespace |
| Analytics & Tracking | Google Analytics 4, Mixpanel, Segment, Hotjar |
| Marketing & CRM | HubSpot, Marketo, Klaviyo, Intercom, Zendesk |
| Frameworks & CDNs | Next.js, Nuxt, React, Cloudflare, AWS CloudFront |
| Payments | Stripe, PayPal, Adyen |

Plus for every site: **page title, meta description, contact email, and social links** (Twitter/X, LinkedIn, GitHub, Facebook).

### Input

| Field | Type | Default | Description |
|---|---|---|---|
| `domains` | array of strings | `["https://cal.com", "https://linear.app"]` | Domains or full URLs to profile |
| `maxConcurrency` | integer | `10` | Max sites processed in parallel |
| `timeoutSecs` | integer | `15` | Per-request timeout in seconds |

#### Example input

```json
{
    "domains": ["shopify.com", "https://stripe.com", "hubspot.com"],
    "maxConcurrency": 10,
    "timeoutSecs": 15
}
```

### Output

One row per domain, pushed straight to the Apify dataset. Example record:

```json
{
    "domain": "cal.com",
    "url": "https://cal.com/",
    "status_code": 200,
    "technologies": ["Cloudflare", "Google Analytics 4", "Next.js", "React", "Stripe"],
    "technologies_by_category": {
        "Analytics & Tracking": ["Google Analytics 4"],
        "Frameworks & CDNs": ["Cloudflare", "Next.js", "React"],
        "Payments": ["Stripe"]
    },
    "social_links": {
        "twitter": "https://twitter.com/calcom",
        "linkedin": "https://linkedin.com/company/cal-com",
        "github": "https://github.com/calcom",
        "facebook": null
    },
    "email": "hello@cal.com",
    "title": "Cal.com - Scheduling infrastructure for absolutely everyone",
    "meta_description": "Cal.com is an open source scheduling tool..."
}
```

Export results directly to CSV, Excel, JSON, or connect via the Apify API to your CRM, spreadsheet, or lead-scoring pipeline.

### How it works

For each domain, the Actor:

1. Requests the page over HTTP with redirect-following enabled.
2. Matches response headers, HTML, inline scripts, and CDN footprints against a curated signature library.
3. Parses the DOM for `<title>`, meta description, `mailto:` links, footer text, and social profile links.
4. Streams a structured, typed record straight to the dataset — no post-processing needed.

Requests run concurrently (bounded by `maxConcurrency`), so a list of hundreds of domains typically finishes in minutes, not hours.

### Use cases

- **Sales prospecting** — segment target accounts by CMS, CRM, or payment provider before outreach.
- **Competitive intelligence** — track which technologies competitors' customers are adopting.
- **Lead enrichment pipelines** — bolt this onto existing scraped domain lists to add firmographic-style tech signals.
- **M\&A / vendor due diligence** — quickly audit the tech footprint of an acquisition target's public site.

### Notes & limitations

- Detection is based on publicly observable HTTP responses (headers, HTML, inline scripts) — it does not execute JavaScript, so client-side-only integrations loaded after page render may not be detected.
- Contact email extraction relies on `mailto:` links and visible page text; sites that obfuscate emails via JavaScript or forms only will return `null`.
- Be a good web citizen: keep `maxConcurrency` reasonable for very large lists to avoid overloading target sites.

# 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": [
        "https://cal.com",
        "https://linear.app"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("shawnle204/website-tech-stack-contact-enricher").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);
});

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

# Prepare the Actor input

## CLI example

```bash
echo '{
  "domains": [
    "https://cal.com",
    "https://linear.app"
  ]
}' |
apify call shawnle204/website-tech-stack-contact-enricher --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,shawnle204/website-tech-stack-contact-enricher"
        }
    }
}

```

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).
