# Website Technology Stack Detector (BuiltWith Alternative) (`scrapemint/website-tech-stack-detector`) Actor Detect what any list of websites runs: CMS, ecommerce platform, analytics, marketing tools, chat widgets, frameworks, CDN, hosting and payments. One row per domain with evidence. No login, no API key. Pay only for detections. - **URL**: https://apify.com/scrapemint/website-tech-stack-detector.md - **Developed by:** [Ken M](https://apify.com/scrapemint) (community) - **Categories:** Lead generation, Marketing, Developer tools - **Stats:** 2 total users, 1 monthly users, 0.0% runs succeeded, 0 bookmarks - **User rating**: No ratings yet ## Pricing Pay per usage This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

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 (BuiltWith Alternative) Find out what any list of websites runs, without a $295/month BuiltWith plan. Give it domains, it fetches each homepage once and returns one clean row per site: the CMS, ecommerce platform, analytics and marketing tools, chat widgets, JavaScript framework, CDN, hosting, web server and payment providers, each with the evidence that matched. ### What you get One row per website, with: - `cms`, `ecommerce` (the headline platform, e.g. `WordPress`, `Shopify`) - `byCategory` (all detections grouped: `cms`, `ecommerce`, `analytics`, `marketing`, `framework`, `hosting`, `server`, `payments`, `security`, `media`, `testing`, `search`) - `technologies` (every detection with its `evidence`, e.g. `html: cdn.shopify.com` or `header: x-vercel-id`) - `techCount`, `domain`, `finalUrl`, `httpStatus`, `reachable`, `scrapedAt` Detection uses a precision-first signature set (about 100 technologies): vendor-hosted asset URLs, unique JavaScript globals, vendor response headers, and session cookie names. A technology in prose text does not trigger a match. ### Input - `websites` (domains or URLs, one row each, up to 5000 per run) ### Example input ```json { "websites": ["allbirds.com", "basecamp.com", "techcrunch.com"] } ```` ### Uses - Segment lead lists by technology: find the Shopify stores, the HubSpot users, the WooCommerce shops - Qualify prospects before outreach: pitch your Shopify app only to Shopify stores - Competitor and market research: what do the top sites in a niche run - Pairs with the [Website Contact Scraper](https://apify.com/scrapemint/website-contact-scraper): same domain list in, contacts from one, tech stack from the other, join on domain ### Pricing Pay per detection row. A site only costs money when it yields at least one detected technology; unreachable or zero-detection sites are free. The first 10 detection rows of every run are free so you can validate output before you scale up. ### Notes - Each site gets one polite homepage request, no crawling. Tools loaded only on inner pages will not show. - Signatures favor precision over recall: a match means the vendor asset, header, or cookie is actually present. Client-rendered pages can hide some HTML signatures, but headers and cookies still work. - Sites behind aggressive bot protection may be unreachable; those rows are free and marked `reachable: false`. - This Actor reads only public data and never logs in. # Actor input Schema ## `websites` (type: `array`): Domains or URLs to analyze, e.g. apify.com or https://allbirds.com. One row per site. ## `proxyConfiguration` (type: `object`): Optional. Sites are fetched directly with one polite request each, so proxy is off by default. Supply one only if your target sites block datacenter IPs. ## Actor input object example ```json { "websites": [ "apify.com", "allbirds.com", "gymshark.com", "basecamp.com", "techcrunch.com", "ghost.org", "zapier.com", "mailchimp.com", "smashingmagazine.com", "buffer.com", "shopify.com", "stripe.com", "patagonia.com", "glossier.com" ] } ``` # 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 = { "websites": [ "apify.com", "allbirds.com", "gymshark.com", "basecamp.com", "techcrunch.com", "ghost.org", "zapier.com", "mailchimp.com", "smashingmagazine.com", "buffer.com", "shopify.com", "stripe.com", "patagonia.com", "glossier.com" ] }; // Run the Actor and wait for it to finish const run = await client.actor("scrapemint/website-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); }); // 📚 Want to learn more 📖?
