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 - Free BuiltWith & Wappalyzer Alternative Detect 80+ technologies on any website in seconds -- frameworks, CMS, analytics, CDN, payments, marketing tools, and more.

page in Apify Store 2. **Paste website URLs** (e.g., `https://stripe.com`, `https://github.com`) 3. **Click "Start"** and get a full tech stack breakdown as JSON, CSV, or Excel ### Input | Field | Type | Default | Description | |-------|------|---------|-------------| | `urls` | string[] | *required* | Website URLs to scan | | `includeHeaders` | boolean | `true` | Analyze HTTP headers for server/CDN/security info | | `includeMetadata` | boolean | `true` | Include page title, description, favicon | | `categoryFilter` | string[] | all | Only return specific categories (e.g.,

Sales Prospecting by Tech Stack "Find me all companies using Shopify + Stripe" -- Bulk-scan prospect URLs to identify which ones use specific technologies, then prioritize outreach based on tech fit. #### 2. Competitive Tech Analysis Scan your top 20 competitors to understand what frameworks, analytics, and marketing tools they use. Identify technology trends in your industry. #### 3. Technology Migration Planning Before migrating from WordPress to Next.js, scan 50+ sites that already made the switch to understand common technology companions (CDN, analytics, etc.). #### 4. Agency Website Audits Quickly audit a prospect's website and identify outdated technologies, missing analytics, and security gaps. Generate a tech audit report for your sales process. #### 5. Market Research at Scale Scan 1,000+ websites in a vertical to produce technology adoption reports: "What percentage of e-commerce sites use Stripe vs. PayPal?" #### 6. Security Posture Assessment Check security headers (HSTS, CSP, X-Frame-Options) across your portfolio of sites to identify which ones need security hardening. ### Available Categories Use these in the `categoryFilter` input to narrow results: `framework`, `cms`, `analytics`, `cdn`, `payment`, `marketing`, `hosting`, `javascript-library`, `css-framework`, `security`, `font`, `tag-manager`, `advertising`, `chat`, `video`, `database`, `server` ### FAQ **Q: How many technologies can this detect?** A: 80+ technologies across 17 categories, with new technologies added regularly. Covers the most popular and business-relevant tools. **Q: How does confidence scoring work?** A: Each technology has multiple detection patterns (HTML signatures, HTTP headers). Confidence reflects the percentage of patterns matched: 100% = all patterns found (definite), 50% = minimum one pattern found (likely). Higher confidence = more certain detection. **Q: Can I scan thousands of URLs?** A: Yes. Processing scales linearly. Use the `delayMs` parameter to control request pacing. For 1,000+ URLs, consider setting `includeHeaders: false` for faster processing. **Q: Does this detect server-side technologies?** A: Partially. Server-side frameworks are detected via HTTP response headers (e.g., `X-Powered-By: Express`) and HTML fingerprints. Pure backend technologies without client-facing signatures are not detectable. **Q: How does this compare to BuiltWith?** A: BuiltWith has a larger technology database (50,000+) built over 15+ years with historical data. This Actor detects 80+ of the most business-relevant technologies in real-time, for free. For most sales prospecting and competitive analysis, 80+ technologies covers 95%+ of practical use cases. **Q: Can I schedule regular scans?** A: Yes. Use Apify's built-in scheduler to monitor technology changes over time. Track when competitors adopt new tools or switch frameworks. ### Pricing Pay Per Event -- charged per URL scanned. Typical cost: $0.01-0.05 per URL depending on response time. Free Apify tier available for testing. # Actor input Schema ## `urls` (type: `array`): List of website URLs to analyze. Enter homepage URLs for best results (e.g., 'https://stripe.com', 'https://shopify.com'). Supports any publicly accessible URL. Bulk processing supported. ## `includeHeaders` (type: `boolean`): Analyze HTTP response headers for additional technology signals (server type, CDN, security headers, caching). Slightly slower but provides more complete results. ## `includeMetadata` (type: `boolean`): Include page title, meta description, favicon, and Open Graph data alongside tech stack results. ## `categoryFilter` (type: `array`): Only return technologies in these categories. Leave empty for all categories. Options: 'framework', 'cms', 'analytics', 'cdn', 'payment', 'marketing', 'hosting', 'javascript-library', 'css-framework', 'security', 'font', 'tag-manager', 'advertising', 'chat', 'video', 'database', 'server'. ## `delayMs` (type: `integer`): Milliseconds to wait between each URL request. Lower = faster but higher risk of rate limiting. Recommended: 500-2000ms. ## Actor input object example ```json { "urls": [ "https://stripe.com", "https://github.com" ], "includeHeaders": true, "includeMetadata": true, "categoryFilter": [], "delayMs": 1000 } ``` # API You can run this Actor programmatically using our API.
