## 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

## 🚀 BuiltWith Technology Usage Scraper

Easily collect **technology profiles** from [BuiltWith](https://builtwith.com) in bulk!\
Perfect for enrichment pipelines, sales ops, competitive intelligence, and research workflows.\
This scraper transforms a list of domains into fully structured JSON describing all technologies used.

***

## 🔥 Official Integration

This is the **official** Apify integration from BuiltWith Pty Ltd — accept no imitations!\
Other “BuiltWith scrapers” floating around out there will either:

- ❌ not work at all
- 🤡 return the wrong technology results as we like to mess with scrapers
- 🐒 or in some cases… just scream loudly and throw JSON everywhere

Stick with the real one. Your data (and your sanity) will thank you.

***

### 📝 Input

#### **🌐 Root Domains**

Provide a list of **root domains** such as:

- `example.com`
- `airbnb.com`
- `builtwith.com`

***

### 📤 Output

Each domain produces a **rich JSON object** containing:

| Field        | Description |
|--------------|-------------|
| `domain`     | The input domain, normalized and validated |
| `techs[]`    | Array of detected technologies |
| `name`       | Human-readable technology name |
| `tag`        | A simplified tag such as `analytics`, `cdns`, `framework`, `host`, etc. |
| `categories` | List of BuiltWith categories |
| `link`       | Official reference URL |

#### **📘 Example Output**

## 📘 Example Output

```json
{
    "domain": "builtwith.com",
    "techs": [

# Actor input Schema

## `startDomains` (type: `array`):

Domains to get technology information for.

## `maxRequestsPerCrawl` (type: `integer`):

Maximum number of requests that can be made by this crawler.

## Actor input object example

# 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 = {
    "startDomains": [
        "builtwith.com"
    ],
    "maxRequestsPerCrawl": 10000000
};

// Run the Actor and wait for it to finish
const run = await client.actor("builtwith/builtwith-official-technology-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);
});

```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 = {
    "startDomains": ["builtwith.com"],
    "maxRequestsPerCrawl": 10000000,
}

# Run the Actor and wait for it to finish
run = client.actor("builtwith/builtwith-official-technology-scraper").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 '{
  "startDomains": [
    "builtwith.com"
  ],
  "maxRequestsPerCrawl": 10000000
}' |
apify call builtwith/builtwith-official-technology-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,builtwith/builtwith-official-technology-scraper"
        }
    }
}

```

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).
