## 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

## Tech Stack Detector — Bulk Website Technology Lookup

Detect the technology stack of any website in bulk. Identify 500+ technologies across 40+ categories including frameworks, CMS platforms, analytics tools, CDNs, hosting providers, chat tools, payment processors, security services, and more — with no API key required.

Uses five detection vectors inspired by the Wappalyzer open-source project:

- **HTTP response headers** — Server, X-Powered-By, CDN markers, cache headers
- **HTML body patterns** — Framework fingerprints, SDK includes, class names
- **Meta generator tags** — `<meta name="generator">` for CMS/SSG detection
- **Script source URLs** — `<script src>` patterns for analytics, CDN, and widget SDKs
- **Cookies** — Session cookies, framework markers, consent flags
- **Implies logic** — If WordPress is detected, PHP is automatically added; if Next.js is detected, React and Node.js are added

---

### Use cases

- **Lead qualification** — Filter prospects by their tech stack before outreach. Target companies using Salesforce, HubSpot, or Shopify.
- **Competitor research** — Discover what your competitors are built on and which tools they use.
- **Sales prospecting** — Find companies using a technology your product integrates with or replaces.
- **Agency audits** — Quickly audit a client's existing stack before a migration or redesign project.
- **Market research** — Analyse what CMS, analytics, or hosting platforms a segment of the market has adopted.
- **Due diligence** — Verify the tech stack of a company you're acquiring or partnering with.

### Pricing

**$0.003 per URL successfully analysed** (pay-per-event pricing).

- Failed requests (timeouts, network errors) are **not charged**.
- 1,000 URLs = $3.00
- 10,000 URLs = $30.00

***

### Performance

- Default concurrency: 5 parallel requests
- Typical latency: 500-1500 ms per URL (single HTTP request per site)
- Cap at 50 concurrent for large batches

***

### Limitations

- Detection is based on publicly visible signals in HTTP headers, HTML source, meta tags, script URLs, and cookies. Server-side technologies that leave no client-side traces may not be detected.
- Sites behind heavy bot protection (Cloudflare challenges, JavaScript-only rendering without static HTML) may return limited results.
- JavaScript-rendered content is not executed — detection is based on the initial HTML response.

***

### No API key required

This actor makes a single HTTP request per URL using a standard browser User-Agent. No authentication, no third-party services, no rate-limit tiers to manage.

# Actor input Schema

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

List of website URLs to analyze. Include https:// or the actor will add it automatically.

## `usePlaywright` (type: `boolean`):

Enable JS framework detection (React, Vue, Angular, Next.js, etc.) and DOM-based detection. Uses a real browser — slower but detects 3,300+ additional technologies invisible to HTTP-only scanning. Recommended for comprehensive analysis.

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

Number of parallel HTTP requests (1-50). Ignored in Playwright mode. Default: 5.

## Actor input object example

```json
{
  "urls": [
    "https://shopify.com",
    "https://github.com",
    "https://stripe.com"
  ],
  "usePlaywright": false,
  "maxConcurrency": 5
}
```
