## 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

## Tech Stack Detector: Website Technologies + Email & SaaS (DNS)

Find out what any website is built with — and which business tools the company behind it uses — for **$2 per 1,000 websites**. Paste domains, get one clean row per site.

### What you get for each website

**From the website (7,000+ fingerprints, Wappalyzer-compatible):**

- CMS and site builders (WordPress, Shopify, Webflow, Wix, Squarespace, Drupal, HubSpot CMS...)
- JavaScript frameworks and libraries (React, Next.js, Vue, Nuxt, Angular, jQuery...) with **versions** when exposed
- Analytics, tag managers, A/B testing, chat widgets, marketing automation, ad pixels
- Ecommerce platforms, payment providers, CDNs, hosting, web servers, programming languages
- Implied technologies (e.g. WordPress → PHP + MySQL), each with a confidence score and category

**From DNS (what the HTML never shows):**

- `emailProvider` — Google Workspace, Microsoft 365, Zoho, Proton, Mimecast, Proofpoint...
- `emailSenders` — tools allowed to send email for the domain (SPF): SendGrid, HubSpot, Mailchimp, Salesforce, Zendesk, Amazon SES, Postmark, Klaviyo...
- `verifiedServices` — SaaS accounts the company verified with DNS TXT records: Atlassian, DocuSign, Adobe, Stripe, Zoom, Slack, OpenAI, Miro, Apple, Meta Business...
- `dnsProvider` (Cloudflare, Route 53, Azure DNS...) and `dmarcPolicy`

**Plus:** page title, meta description, language, generator, server header, HTTPS, response time, security headers, and the company's official social profiles (LinkedIn company page, X, Facebook, Instagram, YouTube, GitHub, TikTok).

### Why this one

- **Cheap and fast.** Plain HTTP + DNS, no headless browser, so it's quick and costs $0.002 per site. 1,000 sites ≈ $2.
- **DNS intelligence included.** Knowing a lead uses Microsoft 365 + HubSpot + DocuSign is often more useful for sales than knowing their jQuery version.
- **Failed sites are free.** Timeouts, DNS errors, blocked sites (HTTP 4xx/5xx with nothing detected) and invalid URLs are returned as error rows and **not charged**.
- **Spreadsheet-friendly.** `technologyNames` and `byCategory` for quick filtering, full `technologies` array for detail.

### Use cases

- Lead generation and list building: "all Shopify stores using Klaviyo", "companies on Microsoft 365 using Salesforce"
- Sales and agency prospecting, competitor research, market sizing by technology
- Enriching CRM accounts with tech and email-provider data
- Security and IT audits of your own domains (DMARC, HSTS, CSP)

### Input

```json
{
  "urls": ["stripe.com", "wordpress.org", "https://www.shopify.com"],
  "dnsLookup": true,
  "minConfidence": 50,
  "includeEvidence": false
}
```

Domains without `https://` are fine. The homepage (or the exact URL you give) is fetched once, following redirects.

### Output (shortened, illustrative values)

```json
{
  "domain": "wordpress.org",
  "statusCode": 200,
  "title": "Blog Tool, Publishing Platform, and CMS – WordPress.org",
  "technologyCount": 12,
  "technologyNames": ["WordPress", "PHP", "Nginx", "Google Tag Manager", "..."],
  "byCategory": { "CMS": ["WordPress"], "Web servers": ["Nginx"], "Programming languages": ["PHP"] },
  "technologies": [{ "name": "WordPress", "version": "7.2", "categories": ["CMS", "Blogs"], "confidence": 100, "website": "https://wordpress.org", "implied": false }],
  "emailProvider": "Google Workspace",
  "emailSenders": ["Google Workspace", "SendGrid"],
  "verifiedServices": ["Atlassian", "DocuSign", "Stripe"],
  "dnsProvider": "Amazon Route 53",
  "dmarcPolicy": "reject",
  "socialProfiles": { "linkedin": "https://linkedin.com/company/wordpress", "x": "https://x.com/WordPress" }
}
```

### Pricing

Pay per result: **$0.002 per website analyzed** ($2 per 1,000), plus a tiny Apify start fee per run. Error rows are free. Set *Maximum cost per run* to cap spend — the Actor stops cleanly when it's reached.

### Limitations

- Detection is static (HTML, headers, cookies, script URLs, meta tags, DOM). Technologies that only appear after JavaScript runs, or only on inner pages, may be missed — just like any non-browser detector. Pass specific URLs (e.g. `/pricing`, `/checkout`) if needed.
- Sites behind aggressive bot protection may return an error row (not charged).
- DNS data shows what is configured, which can include services no longer in active use.

### Legal

Only public information is used: the public homepage a browser would see and public DNS records. No logins, no personal data — the Actor does not collect emails or people. Technology fingerprints come from the open-source [wappalyzergo](https://github.com/projectdiscovery/wappalyzergo) project (MIT license). Use the results in line with applicable law and the target sites' terms.

# Actor input Schema

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

Domains or URLs to analyze, one per line (e.g. stripe.com or https://www.shopify.com). The homepage (or the exact URL you give) is fetched once.

## `dnsLookup` (type: `boolean`):

Look up MX, SPF, TXT verification records, nameservers and DMARC to detect the email provider (Google Workspace, Microsoft 365...), email-sending tools (SendGrid, HubSpot, Mailchimp...) and verified SaaS accounts (Atlassian, DocuSign, OpenAI, Stripe...).

## `minConfidence` (type: `integer`):

Hide technologies detected with lower confidence (0-100).

## `includeEvidence` (type: `boolean`):

Add why each technology was detected (header, script URL, meta tag, cookie, HTML pattern).

## `maxSites` (type: `integer`):

Stop after this many websites (0 = no limit).

## `concurrency` (type: `integer`):

How many websites to analyze in parallel.

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

Give up on a site after this long. Failed sites are not charged.

};

// Run the Actor and wait for it to finish
const run = await client.actor("globose_talent_mn9/tech-stack-detector").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## CLI example

```bash
echo '{
  "urls": [
    "stripe.com",
    "wordpress.org",
    "https://www.shopify.com"
  ],
  "maxSites": 3
}' |
apify call globose_talent_mn9/tech-stack-detector --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,globose_talent_mn9/tech-stack-detector"
        }
    }
}
```

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).
