## Pricing

from $0.93 / 1,000 website analyzeds

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 Detector: CMS, Analytics, CDN and 290+ Technologies

**Find out what any website is built with.** Give this tech stack detector a list of domains and get, for each site, the CMS, ecommerce platform, JavaScript framework, analytics and ad pixels, chat and email-marketing tools, payment providers, CDN, hosting and web server, with the evidence behind every finding. A fast, low-cost alternative to manual Wappalyzer or BuiltWith lookups for whole lists of websites.

### What can this technology detector find?

**Over 290 technologies in more than 40 categories**, including:

- **CMS and site builders:** WordPress, Shopify, Wix, Squarespace, Webflow, Drupal, Joomla, Ghost, HubSpot CMS, BigCommerce, Magento, WooCommerce
- **Frameworks:** React, Next.js, Vue, Nuxt, Angular, Svelte, Gatsby, Astro
- **Analytics and ads:** Google Analytics 4, Google Tag Manager, Meta Pixel, TikTok Pixel, LinkedIn Insight, Hotjar, Segment, Mixpanel, Plausible, Matomo, Microsoft Clarity
- **Marketing and chat:** HubSpot, Intercom, Drift, Zendesk, Crisp, Tawk.to, Klaviyo, Mailchimp
- **Payments, CDN and hosting:** Stripe, PayPal, Cloudflare, Fastly, Akamai, Amazon CloudFront, Vercel, Netlify
- Plus fonts, cookie-consent tools, review widgets, search, A/B testing, error tracking and security services.

Each finding has a **confidence** (high for headers, cookies, meta tags and script URLs; medium for HTML patterns) and its **evidence**, so you can trust or check every result.

### What data do you get?

| Field | Description |
|---|---|
| `url`, `finalUrl`, `domain` | What you entered and where it ended up after redirects |
| `status`, `statusCode` | ok, http_error or blocked, and the HTTP code |
| `title`, `description`, `language` | Basic page info |
| `technologies` | List of `{name, category, confidence, evidence}` |
| `categories` | Category to technology names |
| `cms`, `ecommerce`, `frameworks`, `analytics`, `cdn`, `hosting` | Quick columns for filtering |
| `server`, `redirects`, `responseTimeMs`, `htmlBytes`, `technologyCount` | Technical details |

### Who uses it?

- **Sales and business-development teams** qualifying leads by the tools a prospect uses ("Shopify stores using Klaviyo", "WordPress sites without analytics").
- **Agencies and freelancers** preparing audits and pitches.
- **Software companies** sizing a market or tracking competitors' adoption.
- **Researchers and investors** studying technology trends across lists of companies.

### How to use it

1. Click **Try for free** (or **Start**).
2. Paste **Websites**, one per line (bare domains work).
3. Run it. Most sites take under a second each.
4. Filter the results by the quick columns, or export to Excel, CSV or JSON.

### Input example

```json
{
  "urls": [
    "https://wordpress.org",
    "https://nextjs.org",
    "https://www.nalgene.com",

### How much does it cost?

**$1.50 per 1,000 websites** ($0.0015 each), plus a $0.00005 start fee per run. You only pay for sites that answered, unless you turn on "Include sites that could not be reached".

| You check | You pay |
|---|---|
| 100 websites | $0.15 |
| 1,000 websites | $1.50 |
| 20,000 websites | $30.00 |

**Volume discounts on higher Apify plans.** The prices above are for the Apify Free plan. On paid plans the per-result price drops automatically: about 15% lower on Bronze, 25% lower on Silver and 38% lower on Gold and above.

### Use it via API, Make, Zapier, n8n or an AI agent

**Apify API.** Start a run and get the results back in one HTTP request (replace `YOUR_API_TOKEN` with the token from Apify Console > Settings > Integrations):

```bash
curl -X POST "https://api.apify.com/v2/acts/plotpointtech~website-technology-detector/run-sync-get-dataset-items?token=YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"urls": ["https://wordpress.org", "https://nextjs.org", "https://www.nalgene.com", "allbirds.com"], "timeoutSecs": 25}'
```

For longer jobs, start the run asynchronously and read the dataset when it finishes. Official `apify-client` libraries exist for Python and JavaScript; the **API** tab on this page has ready-made code.

**No-code automation.** Connect the tool to **Make, Zapier, n8n, Google Sheets, Slack, Airtable** or any webhook with Apify integrations, and use **Schedules** in Apify Console to run it hourly, daily or weekly.

**AI agents (MCP).** Give Claude, ChatGPT, Cursor, VS Code or any MCP-compatible agent direct access to this tool through the hosted Apify MCP server. Add this server URL to your client:

```
https://mcp.apify.com?tools=plotpointtech/website-technology-detector
```

The agent can then call the tool with the same input fields shown above and read the results.

### FAQ

**Is it legal to detect a website's technologies?**
Yes. The tool requests each public home page once, the way a browser does, and reads what the server openly sends. It does not log in or get around bot checks.

**How does it compare with Wappalyzer or BuiltWith?**
It uses the same kind of signals (headers, cookies, meta tags, script URLs and HTML patterns) on the live home page, with evidence for each match. It does not keep historical data or check every inner page.

**Why are some tools missing?**
Only the home page is checked. Tools loaded later by a tag manager, only on inner pages, or only after cookie consent may not be visible.

**What does "blocked" mean?**
The site answered with a bot check (for example a Cloudflare challenge). CDN and security headers are still reported; page-level technologies are not.

**How many websites can I check at once?**
Thousands per run. Sites are checked 10 at a time by default.

# Actor input Schema

## `urls` (type: `array`):

Website URLs or bare domains, one per line (e.g. example.com). Each one is a result.

## `includeFailedSites` (type: `boolean`):

## `timeoutSecs` (type: `integer`):

Give up on a site after this many seconds.

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

How many sites to fetch at the same time.

## 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).
