See what any website is built with: CMS, ecommerce platform, JavaScript framework, analytics and ad pixels, cookie banner, chat widget, payments, CDN and hosting. Works on a list of sites at once and checks around 180 technologies. Handy as a quick Wappalyzer or BuiltWith style lookup.

## 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 Detector (CMS, Analytics, Frameworks)

Paste in a list of websites and you get back what each one runs on. That covers the CMS (WordPress, Drupal, Ghost, Statamic and others), the shop platform if there is one (Shopify, WooCommerce, Magento, BigCommerce), the front-end framework (React, Next.js, Vue, Angular, Astro), analytics and tag managers, ad pixels, cookie banners, chat widgets, payments, CDN and hosting.

Each result is grouped by category and shows how it was detected, plus the version when the site gives it away. You pay per site checked, so it works out cheap for one-off lookups and big lists alike.

### What it does

- Picks up the web server, CDN and hosting from the HTTP headers
- Spots the CMS, site builder and framework from the page itself
- Finds analytics, ad pixels, chat and other third-party tools, including ones loaded by inline scripts
- Shows version numbers when a site gives them away
- Groups everything by category and shows where each one was found
- Ignores tools that are only mentioned in the page text
- One bad address doesn't stop the rest of the list
- Refuses private and internal addresses

### Use cases

- Build lead lists by platform, for example every Shopify or WordPress store in a spreadsheet of domains.
- Check which analytics, chat or marketing tools a company uses before a sales call.
- Compare your stack with competitors'.
- Speed up SEO and agency audits: CMS, tag manager and tracking setup in one go.
- Count how common a technology is across a few hundred sites.

### How to use

1. Put one or more website addresses into URLs (https:// is optional).
2. Press Start. Each site takes about a second.
3. Open the results table and export to CSV, Excel or JSON if you need to.

You can also call it from the Apify API, run it on a schedule, or hook it up to Make, Zapier or n8n. AI agents can use it through Apify's MCP server.

### Input

```json
{
  "urls": [
    "https://example.com",
    "https://www.wikipedia.org"
  ]
}
```

### Output

One dataset item per input with fields: `url`, `finalUrl`, `status`, `technologies`, `categories`, `techCount`, `error`.

Here's a real result:

```json
{
  "url": "https://laravel.com",
  "finalUrl": "https://laravel.com",
  "status": 200,
  "technologies": [
    {
      "name": "Fathom",
      "category": "Analytics",
      "version": null
    },
    {
      "name": "Cloudflare",
      "category": "CDN",
      "version": null
    },
    {
      "name": "Statamic",
      "category": "CMS",
      "version": null
    },
    {
      "name": "HubSpot",
      "category": "Marketing automation",
      "version": null
    },
    {
      "name": "PHP",
      "category": "Programming language",
      "version": null
    },
    {
      "name": "Google Tag Manager",
      "category": "Tag manager",
      "version": null
    }
  ],
  "categories": {
    "Analytics": [
      "Fathom"
    ],
    "CDN": [
      "Cloudflare"
    ],
    "CMS": [
      "Statamic"
    ],
    "Marketing automation": [
      "HubSpot"
    ],
    "Programming language": [
      "PHP"
    ],
    "Tag manager": [
      "Google Tag Manager"
    ],
    "Web framework": [
      "Laravel"
    ]
  },
  "techCount": 7,
  "error": null
}
```

### Pricing

Pay per event: **$0.0024 per site analyzed** (successful results only;
failed items are returned with an `error` field and are not charged). Set a maximum charge per run in the run options.

So 100 sites cost about $0.24, and 1,000 cost about $2.40.

### FAQ

**How many technologies does it know?**

Around 180, from web servers and CDNs through to analytics, ad pixels, consent tools, chat, payments and monitoring. Where one thing implies another (Next.js means React, for example) it adds that too.

**Why do some big sites come back with very little?**

A few large sites (big news publishers, Apple) run their own custom setup and host everything themselves, so there isn't much standard to spot. This tool reads the headers and HTML. It doesn't run the page's JavaScript in a browser.

**Am I charged for sites that fail?**

No. If a site can't be reached or the address is invalid, you get an error row and no charge.

**Can I check thousands of sites?**

Up to 500 per run. For more, split the list or schedule several runs.

### Limitations

- It reads headers, cookies and HTML but doesn't run JavaScript, so things loaded later by scripts can be missed.
- Only public http(s) sites. Private and internal addresses are refused.
- Results show the page as it was when checked.

## CLI example

```bash
echo '{
  "urls": [
    "https://example.com"
  ]
}' |
apify call somepineapple/website-tech-detector-tool --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,somepineapple/website-tech-detector-tool"
        }
    }
}
```

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).
