## Pricing

from $0.96 / 1,000 domain scans

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower 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

## Tech Stack Detector - Website Technology Lookup

Detect the technologies used by a website: frameworks, CMS, analytics, CDN, payments, hosting. The Actor fetches one URL with a single HTTP request and matches it against a set of about 90 Wappalyzer-style technology signatures.

No browser, no API key, no start fee.

### How it works

1. Fetches the page via HTTP GET through Apify Proxy (retried up to 3 times on network or HTTP errors)
2. Analyzes **5 signal sources**: HTTP headers, HTML patterns, script URLs, meta tags, cookies
3. Matches against a list of about 90 technology signatures
4. Returns deduplicated results grouped by category

### Input

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `url` | string | Yes | — | Website URL or domain to scan (e.g., `"shopify.com"`) |

### Output

```json
{
    "url": "https://shopify.com",
    "domain": "shopify.com",
    "technologiesFound": 3,
    "technologies": [
        {"name": "Cloudflare", "categories": ["CDN", "Security"], "evidenceCount": 2},
        {"name": "React", "categories": ["JavaScript Framework"], "evidenceCount": 1},
        {"name": "Google Analytics", "categories": ["Analytics"], "evidenceCount": 1}
    ],
    "byCategory": {
        "CDN": ["Cloudflare"],
        "Security": ["Cloudflare"],
        "JavaScript Framework": ["React"],
        "Analytics": ["Google Analytics"]
    },
    "scrapedAt": "2026-10-21T07:22:49.061747+00:00"
}
```

### Input Example

```json
{
    "url": "shopify.com"
}
```

### Pricing

Pay-per-event, **no start fee**: **$1.60 per 1,000 domain scans** on the Apify Free plan, with lower prices on paid plans.

| Event | Free | Starter | Scale | Business | Enterprise |
|-------|------|---------|-------|----------|------------|
| Domain scan (`DOMAIN_SCAN`) | $1.60 | $1.40 | $1.20 | $0.96 | $0.96 |

Prices in USD per 1,000 events.

#### Cost examples (Free plan)

| Domains | Cost |
|---------|------|
| 1 | $0.0016 |
| 100 | $0.16 |
| 1,000 | $1.60 |

### Detected categories

CMS, JavaScript Framework, JavaScript Library, CSS Framework, E-commerce, Analytics, Tag Manager, Marketing, Customer Support, Payment, CDN, Security, Web Server, Hosting, Programming Language, Web Framework, Error Tracking, A/B Testing, Feature Flags, Font, Static Site Generator, Website Builder, CRM, Email, Live Chat.

### Use cases

- **Sales prospecting** — qualify leads by the tools they already use (e.g. find all Shopify stores running Klaviyo)
- **Competitive intelligence** — see which technologies other sites in your market use
- **Technical review** — list the server, CDN and security headers a site exposes
- **Due diligence** — get a first inventory of a company website's technical footprint
- **AI / LLM workflows** — feed the structured JSON output into LLM pipelines for automated analysis

### Limitations

- Scans one URL per run (the homepage or the URL you give), not the whole site.
- Detection is based on the HTML, HTTP headers, script URLs, meta tags and cookies returned by a single request. JavaScript is not executed, so technologies loaded only client-side (e.g. injected by a tag manager) may be missed.
- Only technologies in the built-in signature list (about 90) can be detected; versions are not reported.
- If the site blocks or rejects the request after the retries, the run fails.

```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 = {
    "url": "github.com"
};

// Run the Actor and wait for it to finish
const run = await client.actor("sweet_stickball/tech-stack-scanner").call(input);

// Fetch and print Actor results from the run's dataset (if any)

## CLI example

```bash
echo '{
  "url": "github.com"
}' |
apify call sweet_stickball/tech-stack-scanner --silent --output-dataset

```

## MCP server setup

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

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).
