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. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.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/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 Technology Checker - Tech Stack & CMS Detector Find out what any website is built with. Paste a list of domains, get back the CMS, e-commerce platform, analytics, ad pixels, payment providers, booking system, live chat, email marketing, CRM, CDN and cookie-consent tool each one runs. **180+ technologies. One request per site. You are never charged for a domain that could not be analyzed.** ### What you get per website ```json { "url": "https://www.gymbeam.cz", "httpStatus": 200, "techCount": 8, "categoriesDetected": ["analytics", "cdn", "cms", "cookieConsent", "ecommerce", "reviews"], "technologies": [ "Astro", "Cloudflare", "CookieBot", "Google Cloud CDN", "Google Reviews Widget", "Google Tag Manager", "Magento", "Trustpilot" ], "techStack": { "cms": ["Astro"], "ecommerce": ["Magento"], "analytics": ["Google Tag Manager"], "cookieConsent": ["CookieBot"], "cdn": ["Cloudflare", "Google Cloud CDN"], "reviews": ["Trustpilot", "Google Reviews Widget"] }, "seoSignals": { "titleTag": "...", "metaDescription": "...", "hasCanonical": true }, "contactMethods": { "email": "info@example.cz", "contactForm": true }, "socialPresence": { "facebook": "https://facebook.com/...", "instagram": null } } ```` A markdown report also lands in the key-value store as `SUMMARY`, with category coverage and the most common technologies across everything you checked. ### Detection that survives first-party proxying This is where most tech-stack scanners quietly get it wrong. Larger sites increasingly serve their analytics and consent scripts from their **own** domain to defeat ad blockers. A scanner that only looks for third-party hostnames (`googletagmanager.com/gtm.js`) then reports "no analytics" on a site that is fully instrumented. This checker also matches: - **Container and measurement IDs** in loader and config contexts — so `GTM-XXXXXXX` served from `/metrics/?id=…` is still found - **Consent managers by their JavaScript API** (`Cookiebot.renew()`, `OptanonWrapper`) rather than only their CDN - **Any IAB TCF platform** via `__tcfapi`, whatever the vendor - **Hosted booking platforms** as the site itself — a business whose website *is* a Booksy, Noona, Fresha or Reservio profile genuinely has booking IDs are matched case-sensitively, so ordinary markup like `class="g-recaptcha"` is not mistaken for Google Analytics. ### Categories | Category | Examples | |----------|----------| | CMS | WordPress, Wix, Squarespace, Shopify, Webflow, Joomla, Drupal, Astro, Next.js | | E-commerce | WooCommerce, Shopify, Magento, BigCommerce, PrestaShop, Shoptet, Upgates | | Booking | Booksy, Fresha, Noona, Calendly, Acuity, Mindbody, Reservio, Bookio, Vagaro | | Analytics | GA4, Google Tag Manager, Hotjar, Clarity, Matomo, Plausible, PostHog | | Ad pixels | Meta Pixel, Google Ads, TikTok, Pinterest, LinkedIn, Criteo, Sklik | | Payments | Stripe, PayPal, Square, Klarna, Adyen, GoPay, Comgate, ThePay | | Email marketing | Mailchimp, Klaviyo, ActiveCampaign, Brevo, MailerLite, Ecomail | | Live chat | Intercom, Tidio, Crisp, tawk.to, Zendesk, Smartsupp | | CRM | HubSpot, Salesforce, Zoho, Pipedrive, Freshsales | | Cookie consent | Cookiebot, OneTrust, CookieYes, Osano, Iubenda, any IAB TCF CMP | | CDN / hosting | Cloudflare, CloudFront, Vercel, Netlify, Fastly, Akamai | | Reviews | Trustpilot, Google Reviews, Yelp, Judge.me, Yotpo | | A/B testing | Optimizely, VWO, AB Tasty, LaunchDarkly | | Error tracking | Sentry, LogRocket, Bugsnag, Datadog RUM | | Accessibility | UserWay, AccessiBe, AudioEye, EqualWeb | | Fonts / icons | Google Fonts, Adobe Fonts, Font Awesome | Includes Czech and Slovak tooling that global scanners miss: Shoptet, Upgates, Reservio, Bookio, Reenio, GoPay, Comgate, ThePay, Ecomail, SmartEmailing, Seznam Sklik, Smartsupp. ### Input ```json { "urls": ["gymbeam.cz", "https://shopify.com", "notino.cz"], "includeSignals": true } ``` Domains work without a scheme. You can also pass objects with a `url` field, or paste a newline- or comma-separated list. | Field | Default | Notes | |-------|---------|-------| | `urls` | — | Websites to check (required) | | `includeSignals` | `true` | Adds SEO, conversion, contact and social data at no extra cost | | `proxyConfiguration` | Apify Proxy | Used only to retry sites that block the direct request | | `concurrency` | `10` | Sites checked in parallel | ### Pricing **$0.004 per website analyzed.** Nothing else. #### What you are never charged for | Situation | Charged? | |-----------|----------| | Unreachable host, timeout, or HTTP error | **No** | | Parked domain, "for sale" page, default server page | **No** | | Blank or placeholder page with no readable content | **No** | | Website analyzed | Yes — $0.004 | Every skipped row still appears in the dataset with a `skipReason` and a plain-English `skipDetail`, so a domain never silently disappears from your results — you just do not pay for it. **Example:** 500 domains, 480 reachable → **$1.92**. ### Blocked websites Some sites refuse anonymous requests. When one answers 403, 429 or similar bot protection, the check is retried once through your proxy and the result is flagged with `usedProxy`. Sites that answer normally are fetched directly, so proxy traffic — which bills to your account — stays limited to the ones that need it. Most sites do not block. A few large retailers fingerprint the HTTP client itself rather than the IP, so a proxy will not always get through; those are reported unreachable and not charged for. ### Common uses - **Prospecting** — find businesses missing the software you sell - **Competitive research** — see what stack competitors run - **Partner and agency audits** — inventory a client portfolio in one run - **Lead enrichment** — append tech data to a list you already have - **Market sizing** — measure platform adoption across a vertical Scanning businesses straight from a Google Maps search, with lead scoring and outreach material, is covered by [B2B Lead Generation & Prospecting](https://apify.com/conversational_kermis/lead-qualifier). # Actor input Schema ## `urls` (type: `array`): Websites to check. Domains work without the scheme (example.com). Accepts a plain list of strings or objects with a `url` field. ## `includeSignals` (type: `boolean`): Also return social profiles, contact details, SEO tags (title, meta description, structured data, Open Graph) and conversion elements (forms, CTAs, trust badges). No extra requests and no extra cost — it reuses the same page fetch. ## `proxyConfiguration` (type: `object`): Used only to retry sites that block the direct request (HTTP 403/429 and similar). Sites that respond normally are fetched directly, so proxy traffic stays limited to the ones that need it. ## `concurrency` (type: `integer`): How many websites to check in parallel. ## Actor input object example ```json { "urls": [ "shopify.com", "hubspot.com", "zapier.com" ], "includeSignals": true, "proxyConfiguration": { "useApifyProxy": true }, "concurrency": 10 } ``` # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "urls": [ "shopify.com", "hubspot.com", "zapier.com" ] }; // Run the Actor and wait for it to finish const run = await client.actor("conversational_kermis/website-tech-stack-checker").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); }); // 📚 Want to learn more 📖?
