## 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 Detector — $0.20 per 1,000 websites

Detect the commercially useful technology signals visible on live websites: CMS, ecommerce, frameworks, analytics, marketing tools, payment providers, support widgets, servers, hosting/CDN, and security headers.

### Why this Actor?

- **One predictable row per domain** at $0.20 per 1,000 websites.
- Live HTTP detection — no stale database and no BuiltWith or Wappalyzer API key.
- 70+ high-value fingerprints across eight sales, marketing, and engineering categories.
- Bulk lead enrichment with configurable concurrency and timeouts.
- Security-header score for HSTS, CSP, X-Frame-Options, Referrer-Policy, and Permissions-Policy.
- Failed websites still produce a clearly labeled diagnostic row, so list coverage is auditable.

### Input example

```json
{
  "urls": ["shopify.com", "wordpress.com", "https://apify.com"],
  "categories": ["CMS", "Ecommerce", "Analytics", "Marketing", "Infrastructure"],
  "maxConcurrency": 10,
  "timeoutSeconds": 15,
  "includeSecurityHeaders": true,
  "includeEvidence": true
}
```

### Pricing

Website profiles cost **$0.0002 each ($0.20 per 1,000)** plus a $0.00005 Actor-start event. That is roughly 90% below the $2–$3 per 1,000 pricing shown by several live technology-detector competitors. Apify platform usage is billed under the user's plan.

### Accuracy and responsible use

Detection is evidence-based but not omniscient: server-side or deliberately hidden tools may not be visible, and a matching asset can occasionally create a false positive. Confidence and optional evidence make results reviewable. Only inspect public websites you are allowed to access, respect site terms and robots policies, and do not use results for abusive targeting.

# Actor input Schema

## `urls` (type: `array`):

Bare domains are normalized to HTTPS.

## `categories` (type: `array`):

Leave all selected for the richest output.

## `maxConcurrency` (type: `integer`):

Lower this for slow or sensitive target lists.

## `timeoutSeconds` (type: `integer`):

Stop waiting for a website after this many seconds.

## `includeSecurityHeaders` (type: `boolean`):

Report HSTS, CSP, X-Frame-Options, Referrer-Policy, and Permissions-Policy.

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

Include the matched signal for each detected technology.

# 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 = {};

// Run the Actor and wait for it to finish
const run = await client.actor("scrapesignal_labs/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 = {}

# Run the Actor and wait for it to finish
run = client.actor("scrapesignal_labs/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 '{}' |
apify call scrapesignal_labs/website-tech-stack-detector --silent --output-dataset

```

## MCP server setup

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