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 Technology Stack Detector Detect the complete technology stack of any website. This Apify Actor identifies **140+ technologies** across 20+ categories including CMS platforms, JavaScript frameworks, CSS frameworks, analytics tools, advertising pixels, payment processors, CDNs, hosting providers, and more. ### Why this Actor? - **BuiltWith** charges $295+/month for technology lookups - **Wappalyzer** was acquired and limited its free tier - This Actor provides **full detection at a fraction of the cost** — $5 per 1,000 URLs ### What it detects | Category | Examples | |---|---| | **CMS** | WordPress, Shopify, Wix, Squarespace, Webflow, Drupal, Joomla, Ghost, Magento | | **JavaScript Frameworks** | React, Next.js, Vue, Nuxt, Angular, Svelte, Gatsby, Remix, Ember | | **CSS Frameworks** | Tailwind CSS, Bootstrap, Bulma, Material UI, Chakra UI, Ant Design | | **Analytics** | Google Analytics 4, Mixpanel, Amplitude, Hotjar, Segment, Heap, PostHog, Plausible | | **Advertising** | Google Ads, Facebook Pixel, TikTok Pixel, LinkedIn Insight, Twitter Pixel | | **Payment** | Stripe, PayPal, Square, Braintree, Klarna, Afterpay | | **CDN** | Cloudflare, Fastly, AWS CloudFront, Akamai, KeyCDN | | **Hosting** | AWS, GCP, Azure, Vercel, Netlify, Heroku, DigitalOcean, Fly.io | | **Email Marketing** | Mailchimp, HubSpot, Klaviyo, SendGrid, ConvertKit, ActiveCampaign | | **Chat & Support** | Intercom, Zendesk, Drift, Crisp, LiveChat, Tidio, Tawk.to | | **A/B Testing** | Optimizely, VWO, Google Optimize, LaunchDarkly, AB Tasty | | **Tag Managers** | Google Tag Manager, Segment, Tealium, Adobe Launch | | **Security** | reCAPTCHA, hCaptcha, Cloudflare Turnstile, Sucuri, Wordfence | | **Error Tracking** | Sentry, Bugsnag, Datadog RUM, LogRocket | | **Build Tools** | Webpack, Vite, Parcel | | **SEO** | Schema.org, Open Graph, Yoast SEO, Twitter Cards | | **And more** | Maps, authentication, cookie consent, animations, e-commerce plugins | ### Detection methods The Actor uses multiple detection techniques for high accuracy: 1. **HTML analysis** — meta tags, generator tags, DOM patterns 2. **JavaScript globals** — checks `window` for framework-specific variables (`__NEXT_DATA__`, `Shopify`, etc.) 3. **HTTP headers** — `X-Powered-By`, `Server`, CDN-specific headers 4. **Script URLs** — CDN patterns, library filenames 5. **CSS patterns** — class naming conventions (Tailwind, Bootstrap, MUI) 6. **Cookies** — technology-specific cookie names 7. **DNS records** — CNAME and NS records for CDN/hosting detection 8. **robots.txt** — CMS-specific paths and patterns Each technology gets a **confidence score** (0–100%) based on how many signals matched. Version detection is attempted where possible. ### Input ```json { "urls": [ "https://example.com", "https://shopify.com", "https://vercel.com" ], "maxConcurrency": 5, "navigationTimeoutSecs": 30, "waitForSecs": 3, "checkHeaders": true, "checkCookies": true, "checkDns": true, "checkRobotsTxt": true } ```` | Field | Type | Default | Description | |---|---|---|---| | `urls` | array | (required) | URLs to analyze (max 1,000) | | `maxConcurrency` | integer | 5 | Parallel page analyses | | `navigationTimeoutSecs` | integer | 30 | Page load timeout | | `waitForSecs` | integer | 3 | Extra wait for JS rendering | | `checkHeaders` | boolean | true | Analyze HTTP response headers | | `checkCookies` | boolean | true | Analyze cookie names | | `checkDns` | boolean | true | Perform DNS lookups | | `checkRobotsTxt` | boolean | true | Fetch and analyze robots.txt | | `proxyConfiguration` | object | none | Proxy settings | ### Output Each URL produces a dataset item: ```json { "url": "https://vercel.com", "domain": "vercel.com", "https": true, "technologiesCount": 12, "categories": "Analytics, CDN, CSS Framework, Cookie Consent, Hosting, JavaScript Framework, SEO", "technologies": [ { "name": "Next.js", "category": "JavaScript Framework", "confidence": 100, "evidence": [ { "type": "html", "matches": ["__NEXT_DATA__", "_next/static"] }, { "type": "scripts", "matches": ["_next/static/", "_next/"] }, { "type": "globalJs", "matches": ["__NEXT_DATA__", "__next"] }, { "type": "headers", "matches": ["X-Powered-By: Next.js"] } ], "version": "14.0.3", "website": "https://nextjs.org" }, { "name": "Vercel", "category": "Hosting", "confidence": 100, "evidence": [ { "type": "headers", "matches": ["X-Vercel-Id: iad1::abcdef"] } ], "website": "https://vercel.com" } ], "technologyGroups": { "JavaScript Framework": ["Next.js", "React"], "Hosting": ["Vercel"], "CDN": ["Cloudflare"], "Analytics": ["Google Analytics 4"] }, "analysisTimeMs": 4523, "analyzedAt": "2024-01-15T10:30:00.000Z" } ``` A summary is also saved to the key-value store under the key `SUMMARY`. ### Use cases - **Competitive analysis** — see what technologies your competitors use - **Lead generation** — find companies using specific technologies - **Market research** — understand technology adoption trends - **Security audits** — identify outdated or vulnerable technologies - **Agency prospecting** — find sites built with specific platforms ### Pricing Pay-Per-Event: **$4.00 per 1,000 URLs** analyzed ($0.004 per URL). ### Limitations - Some technologies can only be detected when their JavaScript loads (requires full page render) - Version detection is best-effort and depends on the technology exposing version info - DNS-based detection may not work behind certain proxy configurations - Single-page applications may need longer `waitForSecs` for full detection ### License ISC # Actor input Schema ## `urls` (type: `array`): List of website URLs to analyze. Each URL will be visited and its technology stack detected. Maximum 1,000 URLs per run. ## `maxConcurrency` (type: `integer`): Maximum number of pages to analyze in parallel. Higher values are faster but use more memory. ## `navigationTimeoutSecs` (type: `integer`): Maximum time to wait for page navigation before timing out. ## `waitForSecs` (type: `integer`): Additional seconds to wait after page load for dynamic content to render. ## `checkHeaders` (type: `boolean`): Analyze HTTP response headers for technology hints (X-Powered-By, Server, etc.). ## `checkCookies` (type: `boolean`): Analyze cookie names for technology detection. ## `checkDns` (type: `boolean`): Perform DNS lookups to detect CDN and hosting providers. Adds slight overhead per URL. ## `checkRobotsTxt` (type: `boolean`): Fetch and analyze robots.txt for technology hints. ## `proxyConfiguration` (type: `object`): Proxy settings for the crawler.
