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 ## Website Tech Stack Detector - Identify 2000+ Technologies at Scale Point this actor at any list of URLs and get back the full tech stack of every site — CMS, JavaScript framework, analytics, CDN, e-commerce platform, payment processor, ad networks and 2,000+ more technologies. Pay per result, no monthly subscription. ### What you get - **2000+ technologies** across 60+ categories, confidence-scored - **CMS** — WordPress, Drupal, Joomla, Shopify, Wix, Squarespace, Webflow, Ghost - **JavaScript frameworks** — React, Vue, Angular, Next.js, Nuxt, Svelte, Astro, jQuery - **Analytics & tracking** — Google Analytics, GA4, Hotjar, Mixpanel, Segment, Amplitude - **CDN & hosting** — Cloudflare, Fastly, Akamai, AWS CloudFront, Vercel, Netlify - **E-commerce** — Shopify, WooCommerce, Magento, BigCommerce, PrestaShop - **Marketing & ads** — HubSpot, Marketo, Google Ads, Facebook Pixel, DoubleClick - **Payment processors** — Stripe, PayPal, Square, Adyen, Klarna - **Pre-grouped category view** — filter by `category_summary.cms`, `.cdn`, `.analytics` with one line of code ### Example output ```json { "url": "https://wordpress.org", "final_url": "https://wordpress.org/", "status_code": 200, "technologies": [ { "name": "WordPress", "categories": ["CMS", "Blogs"], "confidence": 100, "website": "https://wordpress.org" }, { "name": "PHP", "categories": ["Programming languages"], "confidence": 100 }, { "name": "Nginx", "categories": ["Web servers", "Reverse proxies"], "confidence": 100 }, { "name": "Google Tag Manager", "categories": ["Tag managers"], "confidence": 100 } ], "category_summary": { "cms": ["WordPress"], "programming_languages": ["PHP"], "web_servers": ["Nginx"], "tag_managers": ["Google Tag Manager"] }, "page_title": "Blog Tool, Publishing Platform, and CMS – WordPress.org", "page_description": "Open source software which you can use to easily create a beautiful website.", "scraped_at": "2026-04-10T17:32:48Z" } ```` ### How to use Drop a list of URLs into the `urls` field and run. Results arrive as one dataset record per URL with the full technology breakdown. Use `category_summary` to filter quickly — e.g. "every site where `category_summary.cms` contains WordPress". #### Input | Parameter | Description | Default | |-----------|-------------|---------| | `urls` | List of websites to analyze | *(required)* | | `includeHeaders` | Include HTTP response headers in output | `true` | | `fetchTimeoutSeconds` | Per-site fetch timeout | `15` | | `userAgent` | Override the User-Agent header | *(modern Chrome)* | | `maxConcurrency` | Parallel URL analysis (max 20) | `5` | | `proxyConfiguration` | Optional Apify Proxy configuration | *(none)* | ### Use cases - **Sales targeting (SaaS)** — find every Shopify store in Germany, every WordPress site with WooCommerce, every Next.js site — for targeted outreach - **Competitive intelligence** — profile your competitors' full tech stack in seconds - **Agency prospecting** — find sites on outdated platforms (Joomla, Drupal 7, classic ASP) as migration prospects - **Market research** — measure CMS/framework adoption across 10,000 sites in your vertical - **Security auditing** — detect outdated software, expose attack surface, flag vulnerable plugins - **Investment due diligence** — validate a target's tech claims ("built on modern React stack") before acquisition - **Partnership scouting** — find every site running a specific tool (e.g. Segment users for integration partnerships) ### Pricing | Event | Price | |-------|-------| | Actor start | $0.001 | | Per URL analyzed | $0.005 | **Example**: Analyze 1,000 URLs = **$5.01** — no subscription, no minimums, pay only for what you scrape. | URLs | Cost | |------|------| | 500 | $2.50 | | 1,000 | $5.00 | | 10,000 | $50.00 | Pay per result. No subscription. A typical 500-site run completes in 3-5 minutes. ### Issues & Feedback Found a bug or got a site that isn't detecting properly?

Include the scheme (https://) for best results. One URL per line. ## `includeHeaders` (type: `boolean`): Include relevant HTTP response headers (Server, X-Powered-By, Cf-Ray, etc.) in the output. Headers are always used for fingerprinting, this only controls the visible output. ## `fetchTimeoutSeconds` (type: `integer`): How long to wait for a website to respond before giving up. ## `userAgent` (type: `string`): Optional. Override the User-Agent header sent when fetching pages. Leave empty to use a modern Chrome User-Agent. ## `maxConcurrency` (type: `integer`): How many URLs to analyze in parallel. ## `proxyConfiguration` (type: `object`): Select a proxy to use when fetching pages. Use Apify Proxy to avoid rate limits on large runs. ## Actor input object example ```json { "urls": [ "https://stripe.com", "https://apple.com" ], "includeHeaders": true, "fetchTimeoutSeconds": 15, "maxConcurrency": 5, "proxyConfiguration": { "useApifyProxy": false } } ``` # Actor output Schema ## `defaultDataset` (type: `string`): Per-URL tech stack detection results. # API You can run this Actor programmatically using our API.
