## Pricing

from $12.00 / 1,000 results

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

### What is Tech Stack Detector?

Tech Stack Detector (a Wappalyzer & BuiltWith alternative) is an Apify Actor that tells you what any website is built on: CMS, e-commerce platform, analytics, ad pixels, e-mail marketing, chat widget, payment provider, framework, cookie-consent tool, and hosting — **one clean row per website**, not per page. It runs on plain HTTP, no headless browser, so a few thousand domains is fast and cheap.

**Pricing:** Tech Stack Detector costs **$20 per 1,000 website results on the Free tier**, with lower rates on paid Apify tiers. A small actor-start fee also applies. Rates checked against the live Pricing data on October 28, 2026.

The live Pricing tab is authoritative. Set **Maximum cost per run** before starting and test one domain before increasing the batch.

### What data does Tech Stack Detector extract?

Tech Stack Detector extracts every signature anchored to something a site can only have if it truly runs it — a vendor CDN hostname, a namespaced variable, a generator tag:

| Field | Type | Description |
|---|---|---|
| `domain` | string | Root domain, `www.` stripped |
| `title` / `description` | string | Homepage title and meta description |
| `generator` | string | `<meta name="generator">` tag, if present |
| `cms` / `ecommerce` | array | CMS and e-commerce platforms |
| `analytics` / `advertising` | array | Analytics tools and ad pixels |
| `emailMarketing` / `chat` / `payments` | array | Marketing, chat, payment tools |
| `frameworks` / `cookieConsent` | array | Frameworks and consent tools |
| `cdn` / `server` | array | Hosting and web server |
| `primaryCms` / `primaryEcommerce` | string | Best single guess |
| `isEcommerce` | boolean | True if a shop platform was found |
| `trackingIds` | object | GA4, GTM, Ads, Meta Pixel, Hotjar, Yandex, TikTok IDs |
| `technologies` | array | Full detections with name, categories, version, confidence (6,000+ from Wappalyzer) |
| `byCategory` | object | Technologies grouped by category for easy filtering |
| `technologyCount` | number | Total unique technologies detected |
| `pagesCrawled` / `scrapedAt` | number/string | Pages fetched, timestamp |
| `error` | string | Error message if domain could not be crawled (null if successful) |

### How to use Tech Stack Detector

1. Paste your websites into **Websites** (bare domains or full URLs).
2. Optionally pick **Technology categories**; empty means everything. Leave **Max pages per website** at 3.
3. Enable **Follow subdomains** for sites like `shop.example.com`, then click **Start** and download results as JSON, CSV, Excel, or HTML.

### Example input

```json
{
  "startUrls": [{ "url": "https://example.com" }],
  "maxPagesPerDomain": 3,
  "categories": ["cms", "ecommerce", "advertising"]
}
```

### Input parameters

| Parameter | Type | Default | Description |
|---|---|---|---|
| `startUrls` | array | apify.com | Websites to fingerprint, one row each |
| `maxPagesPerDomain` | integer | 3 | Page budget per website (1–50) |
| `categories` | array | `[]` (all) | Technology categories to detect |
| `followSubdomains` | boolean | false | Also inspect subdomains |
| `maxConcurrency` | integer | 10 | Parallel requests (1–50) |
| `proxyConfiguration` | object | none | Optional proxy |

### 6,000+ technologies — open-source Wappalyzer fingerprints

Tech Stack Detector now includes **6,000+ technology fingerprints** from the open-source [Wappalyzer ruleset](https://github.com/enthec/webappanalyzer) (GPL-3.0), updated weekly. Every detection includes confidence (0–100) and any detected version number. The `byCategory` field groups results for filtering. Fingerprints are anchored to real signals (HTTP headers, cookies, meta tags, script srcs, inline JS globals) — not brand names — so false positives are rare.

### Pricing

Tech Stack Detector uses pay-per-event pricing: **$0.02 per website result on the Free tier** ($20 per 1,000), $0.016 on Bronze, $0.014 on Silver, and $0.012 on Gold, Platinum and Diamond. The actor-start event is $0.00005 per event; Apify applies one event per GB of Actor memory, with a minimum of one. Platform usage is included in the event pricing. These rates were verified on October 28, 2026; check the live Pricing tab for later changes. Set **Maximum cost per run** before starting.

### Tech Stack Detector vs. BuiltWith and Wappalyzer subscriptions

This Actor fits batch website lookups that need dataset export, API access or separately configured Apify schedules. Detection is based on a bundled snapshot of technology rules rather than a guarantee that every installed tool can be identified. Start with domains whose technology stack you already know, inspect detected names and versions, then increase the batch if the output meets your needs.

### Using Tech Stack Detector with AI agents and MCP

Tech Stack Detector runs on pay-per-event pricing with limited permissions — the two requirements for an Actor to be callable through the Apify MCP server at mcp.apify.com. An agent passes `startUrls` and gets one row per domain back, and connects via n8n, Make, Zapier, or LangChain through Apify's integrations.

### FAQ

**How accurate is it?** Every signature is anchored to something a site can only have if it truly runs that technology, not a brand name in page text.

**Why did it miss a tool I know is there?** Usually Google Tag Manager: tags loaded *through* GTM are injected at runtime and never appear in HTML, which this Actor reads only — it reports the GTM container, not the tags inside it. Raising `maxPagesPerDomain` helps for scripts on missed pages.

**Does it detect Turkish e-commerce platforms?** Yes — Ticimax, IdeaSoft, T-Soft, ikas, Platin Market, iyzico, PayTR, and Shopier.

**Is this legal to run?** The Actor reads only public HTML and collects no personal data. You're responsible for complying with the sites' terms and applicable law.

**How do I control cost?** Set **Maximum cost per run** — narrowing categories and lowering **Max pages per website** also cut compute.

**Can I export as CSV or Excel?** Yes, from the Output tab and API.

# Actor input Schema

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

Enter the websites to fingerprint, one row is returned per website. Use bare domains or full URLs, e.g. example.com or https://example.com.

## `maxPagesPerDomain` (type: `integer`):

Enter how many pages to fetch per website, e.g. 3. The homepage exposes most of the stack; 2-4 pages also catches checkout and marketing scripts that only load on shop or contact pages.

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

Select which technology categories to detect, e.g. cms, ecommerce. Leave empty to detect everything; narrowing the list makes runs cheaper and keeps the output to the columns you care about.

## `followSubdomains` (type: `boolean`):

Turn this on to also inspect subdomains such as shop.example.com, which often run a different platform than the main site.

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

Enter the maximum number of parallel requests, e.g. 10. Lower it if a target site rate-limits you.

## `proxyConfiguration` (type: `object`):

Optional. Select a proxy configuration, e.g. Apify Proxy with the datacenter group, which is enough for most sites and keeps the run cheap.

## `inputDatasetId` (type: `string`):

Take the URLs from another Actor run's dataset, e.g. "aBcD1234". Combined with the list above.

## `inputField` (type: `string`):

Column holding the value, e.g. "url" (the default) or "website". Array columns are flattened.

## Actor input object example

```json
{
  "startUrls": [

# 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": [
        {
            "url": "https://apify.com"
        }
    ],
    "maxPagesPerDomain": 3,
    "maxConcurrency": 10
};

// Run the Actor and wait for it to finish
const run = await client.actor("webdatatools/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 = {
    "startUrls": [{ "url": "https://apify.com" }],
    "maxPagesPerDomain": 3,
    "maxConcurrency": 10,
}

# Run the Actor and wait for it to finish
run = client.actor("webdatatools/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 '{
  "startUrls": [
    {
      "url": "https://apify.com"
    }
  ],
  "maxPagesPerDomain": 3,
  "maxConcurrency": 10
}' |
apify call webdatatools/tech-stack-detector --silent --output-dataset

```

## MCP server setup

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