## 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`).

### What is Tech Stack Detector?

Knowing what a website is built with tells you who to sell to and how. Agencies hunt WordPress sites on old versions, app makers want every Shopify store, ad-tech sellers look for sites without a Meta Pixel, and security teams need to know which servers run outdated software. **Tech Stack Detector** is a Wappalyzer and BuiltWith alternative that scans any list of websites with 3,000+ open-source fingerprints and returns a clean technology profile per site, with the contact details to act on it.

### What does it do?

- **3,000+ technologies** from the maintained open-source Wappalyzer fingerprint set, refreshed every run
- **Versions & confidence** where the site exposes them (e.g. WordPress 6.6, jQuery 3.7)
- **Grouped fields**: cms, ecommerce, analytics, tagManagers, advertising, frameworks, cdn, hosting, webServers, marketingAutomation, liveChat, payment, security
- **Full detail**: every technology with categories, website, SaaS flag and pricing model
- **Contact details (on by default)**: emails, phone links and social profiles (Facebook, Instagram, LinkedIn, X, YouTube, TikTok, GitHub)
- **Bulk & fast**: plain HTTP, no browser, 6 sites in parallel

### Why choose us over cheaper scrapers?

- **Honest output**: limits are documented, missing data is labeled, never invented
- **Clean, consistent schema** ready for Excel, Sheets, BI tools or an LLM
- **No account risk**: no logins, no cookies, no API keys
- **Pay per result** with a built-in cost guard; no subscription, failed items are never charged
- **Fast and light**: no residential proxy, so runs finish in seconds and stay cheap
- **Maintained by IntelScrape** and fixed fast when the source changes

### Who is it for?

- **Agencies & freelancers**: find sites on a platform you specialise in and pitch them
- **SaaS & app sales**: build lists of Shopify, WooCommerce, HubSpot or Webflow users
- **Ad-tech & analytics sellers**: find sites missing GA4, a tag manager or a Meta Pixel
- **Competitive intelligence**: see what tools competitors use
- **Security & IT**: inventory web servers, CMS versions and CDNs across a portfolio
- **Investors & market research**: measure technology adoption across a market

### How to use it

#### In Apify Console (no code)

1. Click **Try for free** / **Start**. The form is prefilled with a working example.
2. Change the inputs (see examples below).
3. Click **Start**, then export the results as **JSON, CSV, Excel, XML or HTML**, or open them in Google Sheets.
4. Optional: **Schedule** the actor to run hourly, daily or weekly.

#### Via API

```bash
curl -X POST "https://api.apify.com/v2/acts/intelscrape~tech-stack-detector/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"domains": ["shopify.com", "wordpress.org", "apify.com"], "contactDetails": true}'
```

Or use the official [Apify JavaScript](https://docs.apify.com/api/client/js/) and [Python](https://docs.apify.com/api/client/python/) clients:

```python
from apify_client import ApifyClient
client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("intelscrape/tech-stack-detector").call(run_input={"domains": ["shopify.com", "wordpress.org", "apify.com"], "contactDetails": true})
for item in client.dataset(run["default_dataset_id"]).iterate_items():
    print(item)
```

#### With AI agents (MCP)

Add Apify's MCP server (`https://mcp.apify.com`) or the [IntelScrape MCP Server](https://apify.com/intelscrape/skip--trace) to Claude Desktop, Cursor, ChatGPT or any MCP client, then ask in plain language, e.g. *"Run intelscrape/tech-stack-detector with the default input and summarise the results."*

### Input examples

**Three sites with contacts (default)**

```json
{
  "domains": ["shopify.com", "wordpress.org", "apify.com"],
  "contactDetails": true
}
```

**Bulk technology-only scan**

```json
{
  "domains": ["example-store1.com", "example-store2.com", "https://www.example.org/shop"],
  "contactDetails": false
}
```

### Output fields

| Field | Description |
|---|---|
| `domain / inputUrl / finalUrl / httpStatus / title` | Site identity |
| `technologyCount` | Number of technologies found |
| `cms / ecommerce / analytics / tagManagers / advertising / frameworks` | Grouped technology names |
| `cdn / hosting / webServers / marketingAutomation / liveChat / payment / security` | More groups |
| `technologies[]` | name, version, confidence, implied, categories, website, saas, pricing |
| `byCategory` | Every category with its technologies |
| `emails / phones / socials` | Contact details (when on) |
| `scannedAt` | Scan time |

#### Sample output

```json
{
  "domain": "wordpress.org",
  "httpStatus": 200,
  "technologyCount": 9,
  "cms": ["WordPress"],
  "webServers": ["Nginx"],
  "frameworks": [],
  "technologies": [
    { "name": "WordPress", "version": null, "confidence": 100, "categories": ["CMS", "Blogs"] },
    { "name": "PHP", "implied": true, "categories": ["Programming languages"] }
  ],
  "socials": { "x": "https://x.com/WordPress" }
}
```

### Pricing (pay per event)

| Event | When it is charged | Price |
|---|---|---|
| **Actor start** | once per run | $0.005 |
| **Site scanned** | per website profiled | $0.002 |
| **Contact details** | per website with emails/phones/socials (on by default; turn off to skip) | $0.001 |

#### Cost examples

| Run | Cost |
|---|---|
| Default run: 3 sites with contacts | $0.014 |
| 1,000 sites with contacts | $3.005 |
| 10,000 sites, technology only | $20.005 |

Platform usage is included in these prices. Set **Max charge per run** in the run options to cap spend; the actor stops cleanly when the limit is reached and keeps everything collected so far.

### Tips for best results

- Input the homepage; it carries most technology signals.
- Filter by the cms or ecommerce field to build platform lead lists.
- Turn off contact details for the cheapest pure technology scan.
- Pair with our Website Contact Scraper for deeper multi-page email collection.

### FAQ

#### How does it compare with Wappalyzer or BuiltWith?

It uses the same open-source fingerprint format as Wappalyzer (the maintained community fork), reading HTML, headers, cookies, meta tags and scripts. It does not run JavaScript, so a few JS-only signals are missed, but it is much cheaper and faster in bulk.

#### Does it detect versions?

Yes, where the site exposes them in code, headers or file names.

#### What is "implied"?

A technology inferred from another (e.g. WordPress implies PHP and MySQL).

#### Are unreachable sites charged?

No. They are listed with the error and not charged.

#### Do I need an API key?

No.

#### How fresh are the fingerprints?

They are downloaded from the open-source project at the start of every run.

### Honest limits

- No JavaScript execution: technologies only visible at runtime may be missed.
- Only the given page is scanned (usually the homepage).
- Sites that block cloud servers may need a proxy (switches automatically).
- Version numbers are reported only when exposed by the site.

```

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).
