## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## Bulk Website Tech Stack Detector — CMS, Analytics, CDN & More

Detect the **technology stack of thousands of websites at once.** Paste a list of sites and get, for each one: **CMS, e-commerce platform, JS framework, analytics & marketing tools, payment providers, CDN, hosting and web server.**

Fast, cheap and keyless — the technographics you need for **sales intelligence, lead scoring, competitor research and market analysis.**

---

### Why this Actor?

Knowing what a website is built with is gold for sales and research: target every Shopify store, find sites still on an old CMS, score leads by their martech stack, or map a market's platform share. Dedicated technographics tools are expensive and per-lookup; this Actor checks a whole list at once, on plain HTTP, so it stays cheap at scale.

- **Sales intelligence** — filter prospects by platform (e.g. all WooCommerce sites, all HubSpot users).
- **Lead scoring & enrichment** — add tech signals to your CRM records.
- **Competitor & market research** — map CMS / e-commerce / CDN share across a list of sites.
- **Agency prospecting** — find sites on platforms you specialize in.

---

### What you get

One record per site:

| Field | Description |
| --- | --- |
| `url` | The site |
| `statusCode` | HTTP status |
| `cms` | Content management system (WordPress, Wix, Drupal…) |
| `ecommerce` | E-commerce platform (Shopify, WooCommerce, Magento…) |
| `frameworks` | JS frameworks (Next.js, React, Vue, Angular…) |
| `analytics` | Analytics (Google Analytics, GTM, Hotjar, Segment…) |
| `marketing` | Marketing & chat (HubSpot, Intercom, Mailchimp, Klaviyo…) |
| `payment` | Payment providers (Stripe, PayPal, Square) |
| `cdn` | CDN (Cloudflare, Fastly, CloudFront, Vercel, Netlify…) |
| `server` | Web server (nginx, Apache, IIS…) |
| `jsLibraries` | Libraries (jQuery, Bootstrap, Tailwind…) |
| `allTechnologies` | All detected technologies |
| `techCount` | How many were detected |
| `error` | Error, if the check failed |
| `scrapedAt` | Timestamp |

---

### Example output

```json
{
  "url": "https://www.shopify.com",
  "statusCode": "200",
  "ecommerce": "Shopify",
  "analytics": "Google Analytics, Google Tag Manager",
  "cdn": "Cloudflare",
  "server": "Cloudflare",
  "allTechnologies": "Shopify, Google Analytics, Google Tag Manager, Cloudflare",
  "techCount": "4",
  "scrapedAt": "2026-07-09T15:00:00.000Z"
}
````

***

### Input

| Field | Type | Default | Description |
| --- | --- | --- | --- |
| `urls` | array | — | **Required.** Websites to analyze. Paste a list or upload/link a text/CSV file. |
| `maxConcurrency` | integer | `50` | Sites analyzed in parallel (up to 300). |
| `timeoutSecs` | integer | `30` | Give up on a site after this many seconds. |

#### Example

```json
{ "urls": [{ "url": "https://shopify.com" }, { "url": "https://wordpress.org" }], "maxConcurrency": 50 }
```

You can also link a **remote text/CSV file** of URLs for very large lists.

***

### Use cases in detail

#### 1. Build a platform-targeted prospect list

Run a list of company sites, then filter `ecommerce = Shopify` (or WooCommerce, Magento…) to get every prospect on the platform you sell to.

#### 2. Lead scoring by martech

`marketing` and `analytics` tell you how sophisticated a prospect is — sites running HubSpot/Segment/Klaviyo are further along and often better leads.

#### 3. Market & competitor research

Aggregate `cms` / `ecommerce` / `cdn` across a market to see platform share and trends.

#### 4. Agency prospecting

Specialize in Webflow, Shopify or WordPress? Find sites on (or off) those platforms to pitch.

***

### How to use it

1. Click **Try for free**.
2. Paste or upload your websites.
3. Click **Start**.
4. Export as **JSON, CSV, Excel**, or via the Apify API.

Hundreds of sites finish in seconds; large lists run cheaply on plain HTTP.

***

### Calling from the API

```bash
curl -X POST "https://api.apify.com/v2/acts/YOUR_ACTOR_ID/runs?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "urls": [{"url":"https://shopify.com"}] }'
```

Then fetch the dataset (JSON/CSV):

```bash
curl "https://api.apify.com/v2/acts/YOUR_ACTOR_ID/runs/last/dataset/items?token=YOUR_APIFY_TOKEN&format=csv"
```

Works with webhooks, Zapier, Make and n8n.

***

### Frequently asked questions

**How does it detect technologies?**
It fetches each site's HTML and response headers and matches them against a library of fingerprints (script URLs, markers, headers). No browser, so it's fast and cheap.

**How many sites can it handle?**
Thousands to millions — it auto-scales concurrency and streams results.

**Does it render JavaScript?**
No — it reads the server-rendered HTML and headers, which is where the vast majority of tech signals live. Technologies injected only by later JS execution may not appear.

**Why did a site show fewer technologies than expected?**
Some stacks are only detectable via runtime JS or are intentionally obscured. The detector focuses on high-confidence signals to keep false positives low.

**Can I filter by platform?**
Yes — export and filter on `cms`, `ecommerce`, `marketing`, etc., or search `allTechnologies`.

***

### Tips

- **Filter on `ecommerce` / `cms`** to build platform-specific prospect lists.
- **Combine with a contact scraper** to turn a tech-targeted list into outreach-ready leads.
- **Raise `maxConcurrency`** for speed on big runs.

***

### Notes

This Actor performs standard HTTP requests and inspects publicly returned HTML and headers to infer technologies. Detection is best-effort (signal-based) and not guaranteed complete. Use on sites you have the right to analyze.
