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. - **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use). - **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`. - **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`. - **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`. - **Any other language** — 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 Scraper (BuiltWith Alternative)](https://scrapers.lat/banners/website-tech-stack-scraper.png)](https://console.apify.com/actors/RxcVDkSTb0VT8yVc5/input) ## Website Tech Stack Scraper (BuiltWith Alternative) Here is one real result, with every field the actor returns (the `title` keeps the source HTML entity exactly as published): ```json { "url": "https://wordpress.org/", "finalUrl": "https://wordpress.org/", "statusCode": 200, "title": "Blog Tool, Publishing Platform, and CMS – WordPress.org", "description": "Open source software which you can use to easily create a beautiful website, blog, or app.", "cmsGuess": "WordPress", "cms": "WordPress", "ecommercePlatform": null, "analytics": null, "tagManagers": "Google Tag Manager", "jsFrameworks": null, "cssFrameworks": null, "marketingPixels": null, "paymentProcessors": null, "chatWidgets": null, "emailMarketing": null, "cdn": null, "hosting": null, "webServer": "Nginx", "fonts": "Google Fonts", "security": null, "server": "nginx", "poweredBy": null, "generator": "WordPress 7.1-RC2-63158", "technologiesAll": "WordPress, Google Tag Manager, Nginx, Google Fonts", "technologyCount": 4, "detectedEmails": null, "emailCount": 0, "detectedPhones": null, "phoneCount": 0, "socialLinks": "https://www.facebook.com/WordPress/,%20https://twitter.com/WordPress,%20https://www.instagram.com/wordpress,%20https://www.linkedin.com/company/wordpress,%20https://www.tiktok.com/@wordpress", "source": "Website Tech Stack", "observedAt": "2026-08-10T14:31:26.873Z" } ``` The most complete website tech-stack scraper available, and a direct BuiltWith alternative. It matches each site's HTML and response headers against a large signature library to reveal the CMS, ecommerce platform, analytics, tag managers, JS and CSS frameworks, marketing pixels, payment processors, chat widgets, email and CRM tools, CDN, hosting, web server, fonts and security tools it uses, and also pulls the page title, description, contact emails and social links as leads. **📥 [Input](https://apify.com/scrapers_lat/website-tech-stack-scraper/input-schema) · 📤 [Output](https://apify.com/scrapers_lat/website-tech-stack-scraper/output-schema) · 💰 [Pricing](https://apify.com/scrapers_lat/website-tech-stack-scraper/pricing) · ▶️ [Examples](https://apify.com/scrapers_lat/website-tech-stack-scraper/examples)** ![Apify](https://img.shields.io/badge/Platform-Apify-1CE1CE?logo=apify\&logoColor=white) ![Coverage](https://img.shields.io/badge/Coverage-Global-blue) ![Output](https://img.shields.io/badge/Output-JSON%20%7C%20CSV%20%7C%20Excel-orange) ![Billing](https://img.shields.io/badge/Billing-Pay%20per%20result-brightgreen) ### Table of contents - [What it does](#what-it-does) - [Quickstart](#quickstart) - [Input reference](#input-reference) - [Output reference](#output-reference) - [Example output record](#example-output-record) - [Run via API and CLI](#run-via-api-and-cli) - [Fetch results](#fetch-results) - [Billing and limits](#billing-and-limits) - [FAQ and troubleshooting](#faq-and-troubleshooting) ### What it does For each website you pass, the actor fetches the homepage HTML and response headers and tests them against a signature library covering more than a hundred technologies across fifteen categories. It returns one record per site listing the detected technologies grouped by category (CMS, ecommerce, analytics, tag managers, JS and CSS frameworks, marketing pixels, payment processors, chat widgets, email and CRM, CDN, hosting, web server, fonts, security), plus a flat `technologiesAll` list, a `technologyCount`, the raw `server` and `x-powered-by` headers, the meta `generator`, and the page title and description. It also extracts contact emails, phone numbers, and social links so the tech profile doubles as a lead record. Categories with no detection are returned as `null`. Use it for sales and competitive intelligence, lead enrichment, and technology market research, as a BuiltWith or Wappalyzer alternative. ### Quickstart Open the actor, paste this into the input, and press Run. It profiles two websites. ```json { "websites": ["shopify.com", "wordpress.org"], "maxWebsites": 10 } ``` Enter each website as a bare domain or full URL, one per line. At least one website is required. ### Input reference | Field | Type | Required | Default | Description | |---|---|---|---|---| | `websites` | string\[] | yes | `["shopify.com", "wordpress.org"]` | One or more domains or URLs to analyze (for example `shopify.com`, `https://wordpress.org`). Each site is profiled for its full technology stack, contact emails, and social links. | | `maxWebsites` | integer | no | `10` | Maximum number of websites to analyze in this run. | At least one website must be provided. ### Output reference One dataset item per website. Category fields are comma-separated strings of technology names, or `null` when nothing was detected in that category. | Field | Type | Description | |---|---|---| | `url` | string | The URL requested. | | `finalUrl` | string | The URL after following redirects. | | `statusCode` | integer | HTTP status code of the fetched page. | | `title` | string | Page title (may contain source HTML entities). | | `description` | string | Meta or Open Graph description, or `null`. | | `cmsGuess` | string | Best single guess of the CMS or platform, or `null`. | | `cms` | string | Detected CMS names, or `null`. | | `ecommercePlatform` | string | Detected ecommerce platforms, or `null`. | | `analytics` | string | Detected analytics tools, or `null`. | | `tagManagers` | string | Detected tag managers, or `null`. | | `jsFrameworks` | string | Detected JavaScript frameworks, or `null`. | | `cssFrameworks` | string | Detected CSS or UI frameworks, or `null`. | | `marketingPixels` | string | Detected marketing and ad pixels, or `null`. | | `paymentProcessors` | string | Detected payment processors, or `null`. | | `chatWidgets` | string | Detected chat and support widgets, or `null`. | | `emailMarketing` | string | Detected email, CRM, and automation tools, or `null`. | | `cdn` | string | Detected CDNs, or `null`. | | `hosting` | string | Detected hosting or PaaS providers, or `null`. | | `webServer` | string | Detected web server, or `null`. | | `fonts` | string | Detected font providers, or `null`. | | `security` | string | Detected security and testing tools (captcha, Sentry, Optimizely), or `null`. | | `server` | string | Raw `Server` response header, or `null`. | | `poweredBy` | string | Raw `X-Powered-By` response header, or `null`. | | `generator` | string | Meta `generator` tag value, or `null`. | | `technologiesAll` | string | Flat comma-separated list of every technology detected. | | `technologyCount` | integer | Number of distinct technologies detected. | | `detectedEmails` | string | Comma-separated public emails found, or `null`. | | `emailCount` | integer | Number of emails found. | | `detectedPhones` | string | Comma-separated phone numbers found, or `null`. | | `phoneCount` | integer | Number of phone numbers found. | | `socialLinks` | string | Comma-separated social profile URLs, or `null`. | | `source` | string | Data source label: `Website Tech Stack`. | | `observedAt` | string | ISO 8601 timestamp of when the record was collected. | | `error` | string | Present only when a site could not be fetched; a diagnostic record is written and not charged. | ### Example output record See the hero example at the top of this page. It is a real record from a live run with input `{"websites": ["shopify.com", "wordpress.org"], "maxWebsites": 10}`. Every field shown is exactly as returned. ### Run via API and CLI Start a run and wait for it to finish, then read the dataset. Replace `` with your Apify API token. Run synchronously and get dataset items in one call: ```bash curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~website-tech-stack-scraper/run-sync-get-dataset-items?token=%3CTOKEN%3E" \ -H "Content-Type: application/json" \ -d '{"websites":["shopify.com","wordpress.org"],"maxWebsites":10}' ``` Start a run asynchronously: ```bash curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~website-tech-stack-scraper/runs?token=%3CTOKEN%3E" \ -H "Content-Type: application/json" \ -d '{"websites":["acme.com","globex.com","initech.com"],"maxWebsites":50}' ``` Apify CLI: ```bash apify call scrapers_lat/website-tech-stack-scraper \ --input '{"websites":["wordpress.org"]}' ``` ### Fetch results Every run writes to a dataset. Fetch items as JSON, CSV, or Excel by changing `format`: ```bash ## JSON curl "https://api.apify.com/v2/datasets/%3CDATASET_ID%3E/items?token=%3CTOKEN%3E&clean=true&format=json" ## CSV curl "https://api.apify.com/v2/datasets/%3CDATASET_ID%3E/items?token=%3CTOKEN%3E&clean=true&format=csv" ## Paginate large datasets curl "https://api.apify.com/v2/datasets/%3CDATASET_ID%3E/items?token=%3CTOKEN%3E&offset=1000&limit=1000" ``` `` is returned as `defaultDatasetId` in the run object. Use `offset` and `limit` to page through large result sets. `clean=true` drops empty and internal fields. ### Billing and limits - **Pay per result.** You are charged per website profile returned (`result` event) that loaded successfully. See the [pricing tab](https://apify.com/scrapers_lat/website-tech-stack-scraper/pricing) for the current per-result price. - **No charge on failure.** If a site cannot be fetched, a diagnostic record with a populated `error` field is written and is not charged. Empty runs cost nothing. - **Spend cap respected.** Set `maxTotalChargeUsd` on the run; once reached, the actor stops emitting and charging further billable results. - **Free Apify plans** are capped at 10 websites per run. Upgrade for higher `maxWebsites`. ### FAQ and troubleshooting **How is this different from BuiltWith or Wappalyzer?** It profiles the same signal (technologies detected from HTML and headers) and returns it as structured JSON, CSV, or Excel per site, priced per result, with contact emails and social links included as a lead bonus. **How does it detect technologies?** By matching the page HTML, response headers, and cookies against a signature library of more than a hundred technologies across fifteen categories. Detections are grouped by category and also flattened into `technologiesAll`. **Why are some categories null?** Nothing in that category was detected on the homepage. Only publicly visible signals are used, so client-side tools loaded after interaction may not appear. **Does it also return contacts?** Yes. It extracts public emails, phone numbers, and social profile links, so each tech profile doubles as a lead record. **A site returned an error. Was I charged?** No. If a site cannot be fetched, a diagnostic record with an `error` field is written and is not billed. **Is this an official tool of the websites analyzed?** No. This actor is independent and reads only data that is publicly available on each website. Use it in accordance with each site's terms of service and applicable law. ### Related scrapers - [Website Contact & Email Scraper](https://apify.com/scrapers_lat/website-contacts-scraper): Emails, phones, socials and addresses from company websites. - [Company Research & Enrichment Tool](https://apify.com/scrapers_lat/company-research-enrichment-tool): Firmographics and enrichment for any company domain. - [Contact Enrichment Tool](https://apify.com/scrapers_lat/contact-enrichment-tool): Enrich a contact from a name and company domain. - [Google Maps Business Leads Scraper](https://apify.com/scrapers_lat/google-maps-business-leads-scraper): Local business leads with contacts from Google Maps. - [G2 Software Reviews Scraper](https://apify.com/scrapers_lat/g2-software-reviews-scraper): Software products with ratings and reviews. ### More scrapers at scrapers.lat Built and maintained by [scrapers.lat](https://scrapers.lat), where we publish scrapers for US and Latin American public platforms: company registries, government data, finance, e-commerce and more.
