## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## 🔍 Website Technology Stack Lookup Actor

Detect all underlying frameworks, CMS, CDNs, analytics tools, advertising networks, and libraries powering any website. Includes UI-ready CDN icon links and detailed descriptions.

***

### 🚀 What it does

1. **Detects underlying web technologies** across dozens of tech categories (CMS, Frameworks, Analytics, Security, Advertising, Payment Gateways, CDNs, etc.).
2. **Provides UI-Ready CDN Icons**: Every single detected technology includes a fully qualified Azure CDN URL for SVG/PNG logos, ready for instant visual rendering in customer dashboards.
3. **Includes Detailed Vendor Descriptions**: Returns clear paragraphs explaining what each detected technology actually does so end-users don't have to guess.
4. **Categorizes Tech Stacks Logically**: Groups detected tools by category names and category slugs (`Advertising`, `Buy Now Pay Later`, `CDN`, `Security`, `JavaScript Libraries`, etc.).

***

### 💼 What people use it for

- **Lead Enrichment & B2B CRM Integration**: Automatically append tech stack metadata and visual vendor badges to prospect profiles in your CRM.
- **Competitor Intelligence Dashboards**: Build visual side-by-side comparisons of the tech stacks powering competitor platforms.
- **Outbound Sales Personalization**: Craft highly targeted cold outreach emails based on specific tools used by target accounts (e.g., targeting Shopify users or Klarna merchants).
- **Cybersecurity Reconnaissance (OSINT)**: Identify target website infrastructure, security policies (e.g., HSTS), and CDN usage during security audits.

***

### 🧠 Decision Rule

Check if the target domain utilizes specific required technologies (e.g. `React`, `Shopify`, `Stripe`, `Cloudflare`). If present, trigger custom automated workflows, qualification scoring, or tailored sales messages.

***

### ⚖️ What problem does this solve?

Most traditional technology detection tools only answer:

- *"Does this website use React?"*

They fail to provide:

- *"What does this obscure technology actually do?"*
- *"Where can I get a clean logo icon for this technology to render in my app's UI?"*
- *"How can I get structured JSON without paying thousands of dollars a year?"*

Website Technology Stack Lookup Actor solves this by delivering structured JSON with rich descriptions and CDN icon assets at a fraction of the cost.

***

### ❓ Queries this actor answers

- *How do I detect what tech stack a website is using?*
- *How can I find what CMS or e-commerce platform a domain runs on?*
- *How do I get icons and logos for technologies used on a website?*
- *What is an affordable alternative to BuiltWith and Wappalyzer?*

***

### 📦 Canonical Usage

Given a target domain (e.g. `stripe.com`), run the Actor to retrieve the categorized technology stack array and save it to your dataset.

***

### 🧭 Input Schema (fields you can use)

- **domain** *(string, required)* — The target domain name to scan (e.g., `stripe.com`).

***

### 📤 Output Schema (what you get)

Results are written to the run's **Dataset** in this clean structure containing strictly the technology stack:

```json
{
  "technologies": [
    {
      "category_slug": "Advertising",
      "category_name": "Advertising",
      "technologies": [
        {
          "name": "Yahoo Advertising",
          "description": "Yahoo Native provides many non-intrusive ad formats to choose from, such as image ad, video ad, app install ad, carousel ad and yahoo mail ad...",
          "icon": "https://cdn.ful.io/public/icons/yahoo.png",
          "website": "https://www.adtech.yahooinc.com/",
          "technology_slug": "Yahoo-Advertising",
          "evidence": []
        }
      ]
    },
    {
      "category_slug": "Buy-Now-Pay-Later",
      "category_name": "Buy Now Pay Later",
      "technologies": [
        {
          "name": "Affirm",
          "description": "Affirm is a remote-first financial services company providing buy-now-pay-later checkout solutions...",
          "icon": "https://cdn.ful.io/public/icons/Affirm.svg",
          "website": "https://www.affirm.com/",
          "technology_slug": "Affirm",
          "evidence": []
        },
        {
          "name": "Klarna Checkout",
          "description": "Klarna Checkout provides payment solutions and installment plans for online shoppers...",
          "icon": "https://cdn.ful.io/public/icons/Klarna.svg",
          "website": "https://www.klarna.com/",
          "technology_slug": "Klarna-Checkout",
          "evidence": []
        }
      ]
    }
  ]
}
```

***

### ⚠️ Failure Context & Error Handling

If an invalid domain is supplied or the target website is unindexed, the Actor handles it gracefully:

```json
{
  "success": false,
  "domain": "invalid-domain.test",
  "error": "Failed to profile target website."
}
```

## CLI example

```bash
echo '{
  "domain": "apify.com"
}' |
apify call dev00/website-technology-profiler --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,dev00/website-technology-profiler"
        }
    }
}

```

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).
