## Pricing

from $4.00 / 1,000 website scanneds

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

## Website Tech Stack Scraper & Technology Lookup API

Detect website technologies with Wappalyzer-compatible HTTP-header and static-HTML fingerprints. This bulk tech-stack scraper / BuiltWith alternative covers CMS platforms, JavaScript frameworks, analytics tools, CDNs, ecommerce platforms, payment processors, hosting providers, and thousands more.

### What it does

Give it a list of website URLs and it returns every detected technology with category labels. Uses Wappalyzer-style fingerprints to identify 7,000+ technologies from HTTP headers and HTML source.

**Detects:**

- CMS platforms (WordPress, Shopify, Drupal, Wix)
- JavaScript frameworks (React, Vue, Angular, Next.js)
- Analytics (Google Analytics, Mixpanel, Hotjar)
- CDNs (Cloudflare, AWS CloudFront, Fastly)
- Ecommerce (Shopify, WooCommerce, Magento)
- Payment processors (Stripe, PayPal, Square)
- Web servers (Nginx, Apache, IIS)
- Programming languages (PHP, Python, Ruby, Node.js)
- Marketing tools, tag managers, A/B testing, live chat, and more

### Input

| Field | Description | Default |
|-------|-------------|---------|
| urls | Website URLs to scan | `https://www.shopify.com` |
| maxResults | Total websites to scan | 1 |

### Output

```json
{
  "url": "https://www.shopify.com",
  "finalUrl": "https://www.shopify.com/",
  "technologies": [
    { "name": "Cloudflare", "categories": ["CDN"] },
    { "name": "Shopify", "categories": ["CMS", "Ecommerce"] }
  ],
  "statusCode": 200,
  "htmlBytesAnalyzed": 5242880,
  "htmlTruncated": true,
  "error": "",
  "scannedAt": "2026-07-24T20:00:00Z",
  "detectionMethod": "Wappalyzer-compatible HTTP header and static HTML fingerprints",
  "interpretationCaveat": "Point-in-time heuristic detection from response headers and up to the first 5 MiB of static HTML..."
}
```

### Use cases

- **Competitive Analysis** -- See what tech stack competitors use
- **Lead Enrichment** -- Add technology data to your prospect lists
- **BuiltWith / Wappalyzer alternative workflows** -- Run bulk website technology lookup without a separate API key
- **Market Research** -- Survey technology adoption across an industry
- **Sales Intelligence** -- Find companies using specific tools (e.g., all Shopify stores, all Stripe users)
- **Security Auditing** -- Identify outdated or vulnerable technologies

### Reliability and interpretation limits

- Results are point-in-time heuristic detections from response headers and up to the first 5 MiB of static HTML.
- A missing technology does **not** prove absence. Client-rendered, blocked, proxied, or obfuscated tools may be missed.
- Fingerprints can produce false positives; verify important findings against the website and vendor configuration.
- Redirects are followed up to five hops and the final fetched URL is returned.
- Failed fetches remain explicit result rows with an `error` instead of disappearing from a bulk job.
- Large Apify runs persist every 25 completed sites so a late failure does not discard all prior work.

### Pricing

$5.00 per 1,000 websites scanned. The default one-site Shopify demo costs at most **$0.005** plus any platform start event. Buyer-set maximum total charge limits are honored before each scan. No API key or external technology-detection service is required.

### How to use

1. Open [Website Tech Stack Scanner - Merchant KYB Enrichment API](https://apify.com/pink_comic/website-tech-stack-scanner) in Apify Console and click **Start** (or **Try for free**).
2. Fill in the input form - start with **Website URLs**, **Max Results**. Every field is optional unless marked required, and the form is prefilled with a working example.
3. Set **Maximum results** to cap your cost, then run the Actor.
4. Download the results as JSON, CSV, Excel, XML or HTML, or pull them with the Apify API.

#### Example input

```json
{
  "urls": [
    "https://www.shopify.com",
    "https://www.stripe.com",
    "https://www.apify.com"
  ],
  "maxResults": 100
}
```

### FAQ

#### How much does Website Tech Stack Scanner - Merchant KYB Enrichment API cost?

$0.005 per website scanned. For example, 1,000 results cost about $5.00. Higher Apify plans get a Store discount.

#### Do I need an API key or login?

No. Just configure the input and run it.

#### Can I run it on a schedule or from code?

Yes. Use Apify Schedules for recurring runs, or call it from the Apify API, the JavaScript or Python client, Make, Zapier, n8n, or any MCP-compatible AI agent.

#### Why did my run return no results?

Your filters are probably too narrow. Remove a filter or broaden the search, then run again. You only pay the result price for records that are actually saved.

#### Is the data accurate and up to date?

Each run fetches live data from the source described above, so results are as current as that source. Verify critical records with the original source before acting on them.

## MCP server setup

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).
