## 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 Technology Stack Detector

Detect evidence-backed website technologies from public headers, HTML, scripts, and linked assets. Built for sales engineering, vendor-displacement, market-mapping, and account-research teams.

**Buyer question:** Which technologies can I prove a target company currently exposes on its public website?

### Start in 30 seconds

```json
{
  "domainsOrUrls": [
    "https://apify.com",
    "https://www.cloudflare.com",
    "https://stripe.com"
  ],
  "maxPagesPerDomain": 3
}
```

Run the sample, inspect the Dataset and `RUN_SUMMARY`, then replace the domains or URLs. Save recurring workflows as Apify Tasks or call the Actor through API, webhooks, Make, n8n, Zapier, ChatGPT, Claude, or Neuton Actors MCP.

### Output schema

Successful output includes `domain`, `websiteUrl`, `technologies`, `categories`, `evidence`, `confidence`, `scrapedAt`. Failed fetches, empty analyses, diagnostics, duplicates, baseline creation, unchanged checks, and unsupported inferences are never billed.

### Buyer workflows

- Qualify target accounts by publicly evidenced CMS, analytics, CRM, payments, CDN, or support tooling
- Build vendor-displacement and partner-ecosystem account lists without unsupported stack guesses
- Compare technology adoption across companies, verticals, or portfolios
- Feed evidence markers into CRM, enrichment, agent, and RAG workflows

### Pricing

Launch price: **$20.00 per 1,000 complete evidence-backed technology analyses**. A paid unit requires a non-empty detected stack and explicit public evidence markers.

### Reliability and limitations

This 256 MB pure-HTTP Actor reads public HTML, response headers, scripts, and links. It does not bypass authentication, CAPTCHAs, paywalls, or private account areas. JavaScript-only pages may expose fewer signals. Evidence rules are intentionally conservative, and source failures produce no paid row.

Technology evidence comes from executable script URLs, relevant resource paths, framework attributes, and specific response headers. Documentation links, commented-out markup, inert template scripts, and keyword mentions are not installation evidence. A public marker indicates an exposed integration or resource, not proof of every tool installed by the company; no detected marker does not prove a technology is absent.

### Responsible use

Use public website evidence for legitimate business research, recruiting, monitoring, and automation. Respect robots directives, site terms, privacy, rate limits, and applicable law. Verify contact data before outreach, maintain suppression controls, and do not infer sensitive traits or use outputs for spam or consequential automated decisions.

# 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("neuton/website-technology-stack-signals").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("neuton/website-technology-stack-signals").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 neuton/website-technology-stack-signals --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,neuton/website-technology-stack-signals"
        }
    }
}
```

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).
