## Pricing

Pay per usage

This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

## 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

⚡ BuiltWith does not support URL paths (e.g., https://www.linkedin.com and not https://www.linkedin.com/br/abc).

## Features

- **Get Technology Profile**

  Return main products.

- **Get Technology Profile (Full)**

  Returns main products and sub-products.

- **Get Company Profile**

## How it works.

1. Enter the website(s) to be analyzed (e.g., apify.com).

2. Select a process to run (e.g., Get Technology Profile).

3. Run it! 🎉

## About concurrency

Set the "Maximum concurrent requests" parameter to define how many requests will be sent to BuiltWith in parallel.

Additionally, there is a limit of requests per minute set by the "Concurrency coefficient".

E.g., reaching 25 requests (maximum requests 5 \* coefficient 5) within a minute will pause the actor for the remaining of the 60 seconds.

The higher the maximum and coefficient, the more chances you are to be blocked.

### Support

🛑 Always use a high-quality or custom proxy and set a reasonable waiting time.

Otherwise, running this actor against a high number of websites will likely get you blocked.

Open a new issue for bugs. Please share your Run URL.

Cheers!

# Actor input Schema

## `process` (type: `string`):

Process to run.

## `startUrls` (type: `array`):

The URLs of websites you want to get data from.

## `waiting` (type: `integer`):

Pause between each URL.

## `maxReq` (type: `integer`):

Recommended: 5.

## `maxReqCoeff` (type: `integer`):

Actor will pause for the remaining of the current minute after reaching maximum requests \* coefficient.

## `proxy` (type: `object`):

Select proxies to be used by your crawler.

## Actor input object example

```json
{
  "process": "gt",
  "startUrls": [
    "apify.com",
    "expensify.com"
  ],
  "waiting": 15000,
  "maxReq": 5,
  "maxReqCoeff": 5,

# 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 = {
    "startUrls": [
        "apify.com",
        "expensify.com"
    ],
    "proxy": {
        "useApifyProxy": true,
        "apifyProxyGroups": [
            "RESIDENTIAL"
        ]
    }
};

// Run the Actor and wait for it to finish
const run = await client.actor("canadesk/builtwith-bulk").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 = {
    "startUrls": [
        "apify.com",
        "expensify.com",
    ],
    "proxy": {
        "useApifyProxy": True,
        "apifyProxyGroups": ["RESIDENTIAL"],
    },
}

# Run the Actor and wait for it to finish
run = client.actor("canadesk/builtwith-bulk").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 '{
  "startUrls": [
    "apify.com",
    "expensify.com"
  ],
  "proxy": {
    "useApifyProxy": true,
    "apifyProxyGroups": [
      "RESIDENTIAL"
    ]
  }
}' |
apify call canadesk/builtwith-bulk --silent --output-dataset

```

## MCP server setup

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

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).
