# Website Tech Stack Detector – Technology Lookup API (`rowcraft/website-tech-stack-detector`) Actor Find the technologies behind a list of websites: CMS, e-commerce platform, analytics, tag managers, ad pixels, consent tools, chat, CDN and payments, from one polite home-page request per domain. robots.txt obeyed, no personal data, pay only per analysed domain. - **URL**: https://apify.com/rowcraft/website-tech-stack-detector.md - **Developed by:** [Rowcraft](https://apify.com/rowcraft) (community) - **Categories:** Lead generation, SEO tools - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, 0 bookmarks - **User rating**: No ratings yet ## Pricing from $1.00 / 1,000 domains This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events. Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have. Learn more: https://docs.apify.com/actors/running/actors-in-store.md#pay-per-event ## What's an Apify Actor? An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes. 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. Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md. ## 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. Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run. For examples already wired to this Actor's own input schema, see the [API](#api) section below. Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`). # README ## Website Tech Stack Detector: Technology Lookup API Find out which technologies a **website** runs on: its CMS, e-commerce platform, analytics, tag manager, ad pixels, cookie consent tool, live chat, CDN, hosting, web server, payment providers, frameworks, A/B testing, e-mail marketing and rating widgets. Give the actor a list of domains or URLs; it reads each home page once, politely, and returns one row per website with every technology it found, its version when the page shows it, and the evidence behind each detection, as JSON, CSV or Excel. The detection rules are Rowcraft's own: 336 fingerprints in 41 categories, written and checked on real home pages, built for precision first. A technology is reported only when the page shows a clear sign of it, so a WooCommerce shop is not tagged as VTEX because the word "vtex" appears somewhere in its code. ![Input form of Website Tech Stack Detector – Technology Lookup API](https://api.apify.com/v2/key-value-stores/7hbQFQdGq61v2OZ2h/records/website-tech-stack-detector-input.png) ### What you get One row per website: - **Identity:** the domain, the address you gave, the home page address after redirects, HTTP status, page title and declared language - **E-commerce platform:** one name (Shopify, WooCommerce, Magento, PrestaShop, VTEX, Salesforce Commerce Cloud, BigCommerce, Shopware...) or null - **Every technology found:** name, category, version (when the page shows it, for example WordPress 7.2 or jQuery 3.7.1) and the evidence: the header, cookie name, generator tag, script address or code snippet that gave it away - **16 ready-made columns** for filtering in a spreadsheet, each a comma-separated list of names (empty when nothing of that kind was found): `cms`, `ecommerce`, `analytics`, `tagManagers`, `advertising`, `consent`, `chat`, `cdn`, `hosting`, `server`, `payments`, `frameworks`, `abTesting`, `emailMarketing`, `ratings`, `other` - **Change tracking:** a `stackHash` of the set of technologies, which changes when a tool is added or removed, and the time of the check The run also writes a `COVERAGE` record with one line per domain you asked for (ok, blocked, robots_disallowed, not_found, error or not_checked, with the reason) and a `RUN_SUMMARY` with counts and the most frequent technologies of the list. ### Why this actor - **Evidence with every detection.** Each technology comes with what was seen on the page, so you can trust it, check it in the page source, or filter it out. - **Precision first.** A technology needs one strong sign (a header, a cookie name, a script from its own servers) or two independent weaker ones. Words that only look like a product name in minified code do not count. - **Own rules, no third-party database.** The 336 fingerprints were written by Rowcraft on the home pages of 126 real websites (shops on Shopify, WooCommerce, VTEX, PrestaShop, Magento, Salesforce Commerce Cloud and others, publishers, software companies and framework sites), then checked on 29 more that were not used to write them. - **Shopify app detection.** Apps that Shopify loads through its own loader (Klaviyo, Attentive, Smile.io, Postscript, Klevu and more) are read from the loader list, where a plain script scan misses them. - **Pay only for websites read.** Domains behind an anti-bot page, disallowed by robots.txt, not found, invalid or repeated in your list are never charged. - **Polite by design.** robots.txt is read and obeyed first, then one request for the home page, one request per second by default. ### How to use it 1. Open the Actor and paste your domains or URLs into **Domains or URLs**, one per line. A column copied from a spreadsheet works, and so do entries separated by commas. 2. For a first try keep the list short, or set **Maximum domains delivered** to a small number. 3. Click **Start**. The status line shows progress; the run stops cleanly at your maximum or at the charge limit you set in the run options. 4. Open the **Dataset** tab: the **Overview**, **Marketing stack** and **Infrastructure** views show the main columns. Download JSON, CSV, Excel, XML or HTML, or send the rows to Google Sheets, Slack, Make, n8n or Zapier with the Integrations tab. 5. Open the `COVERAGE` record in the key-value store to see which domains could not be read and why. 6. To watch a list over time, run it on a schedule with **Only new rows since the last run** turned on: a website is delivered, and charged, again only when its technologies changed. ### Input | Field | What it does | |---|---| | `domains` | Domains (`example.com`) or addresses (`https://www.example.com/shop`), one per line. Only the home page is read; the path is ignored. Up to 100,000 per run. | | `maxItems` | Stop after this many delivered rows. 0 = the whole list. | | `onlyNew`, `stateName` | Deliver a website only when its set of technologies changed since the last run with the same state name | | `notifyUrl`, `notifyWhenEmpty` | A webhook that receives one message when the run ends; see **Automation** below | | `requestIntervalMs` | Pause between requests, default 1000 ms, minimum 250 ms | Example: three websites, one row each. ```json { "domains": ["landyachtz.com", "deathwishcoffee.com", "wordpress.org"] } ``` Example: a weekly check of competitors that reports only the websites whose stack changed, with a Slack message. ```json { "domains": ["competitor-one.com", "competitor-two.com", "competitor-three.com"], "onlyNew": true, "stateName": "competitors", "notifyUrl": "https://hooks.slack.com/services/..." } ``` ### Output 28 fields per row. Empty values are `null`, never missing, so CSV and Excel columns are stable. | Field | Type | Example | |---|---|---| | `id` | string | pipsnacks.com | | `domain` | string | pipsnacks.com | | `inputUrl` | string | `https://www.pipsnacks.com/collections` | | `url` | string | `https://www.pipsnacks.com/` | | `statusCode` | integer | 200 | | `siteTitle` | string | Pip's Heirloom Snacks | The Classics, Made Better with Heirloom Corn | | `language` | string | en | | `ecommercePlatform` | string | Shopify | | `technologyCount` | integer | 10 | | `technologies` | array | \[{"name": "Shopify", "category": "E-commerce", "version": null, "ev… | | `cms` | string | WordPress | | `ecommerce` | string | Shopify | | `analytics` | string | Google Analytics, Hotjar | | `tagManagers` | string | Google Tag Manager | | `advertising` | string | Meta Pixel, TikTok Pixel | | `consent` | string | OneTrust | | `chat` | string | Gorgias | | `cdn` | string | Cloudflare | | `hosting` | string | Netlify | | `server` | string | Nginx, PHP | | `payments` | string | PayPal, Klarna | | `frameworks` | string | Tailwind CSS | | `abTesting` | string | Optimizely | | `emailMarketing` | string | Klaviyo, Postscript | | `ratings` | string | Yotpo | | `other` | string | accessiBe, Adobe Fonts | | `stackHash` | string | ecd687c9fdc5c713 | | `checkedAt` | string | 2026-10-12T16:36:39.772Z | #### Example rows Two real rows from a run (long texts shortened here, complete in the dataset): ```json [ { "id": "deathwishcoffee.com", "domain": "deathwishcoffee.com", "inputUrl": "deathwishcoffee.com", "url": "https://www.deathwishcoffee.com/", "statusCode": 200, "siteTitle": "#1 Organic and #1 Fair Trade Coffee – Death Wish Coffee", "language": "en", "ecommercePlatform": "Shopify", "technologyCount": 9, "technologies": [ { "name": "Cloudflare", "category": "CDN", "version": null, "evidence": [ "header cf-ray", "header cf-cache-status", "header server: cloudflare" ] }, { "name": "Shopify", "category": "E-commerce", "version": null, "evidence": [ "header shopify-complexity-score", "header powered-by: Shopify", "cookie _shopify_essential" ] }, { "name": "Klaviyo", "category": "Email marketing", "version": null, "evidence": [ "script static.klaviyo.com/" ] }, "… 6 more" ], "cms": null, "ecommerce": "Shopify", "analytics": null, "tagManagers": "Google Tag Manager", "advertising": null, "consent": null, "chat": "Gorgias", "cdn": "Cloudflare", "hosting": null, "server": null, "payments": null, "frameworks": null, "abTesting": null, "emailMarketing": "Klaviyo, Postscript", "ratings": null, "other": "Ordergroove, Smile.io, Rebuy", "stackHash": "53e7ff3ea33e41c1", "checkedAt": "2026-10-12T17:56:36.443Z" }, { "id": "landyachtz.com", "domain": "landyachtz.com", "inputUrl": "landyachtz.com", "url": "https://landyachtz.com/", "statusCode": 200, "siteTitle": "Landyachtz Skateboards -

The Apify platform usage of a run (compute and storage) is billed by Apify separately, as for every Actor; the actor runs in 256 MB and spends most of its time waiting between requests. A start event of $0.00005 is charged once per run (Apify default). **Cap your spend:** set *Maximum total charge* in the run options. The actor stops cleanly when the cap is reached and you keep everything delivered until then. The run summary (`RUN_SUMMARY` in the key-value store) says why a run stopped. ### Automation: only new rows, notifications, schedules **Only new rows since the last run.** Turn on `onlyNew` and the actor remembers, for every website it delivered to you, the set of technologies it had (in a key-value store named `rowcraft-website-tech-stack-detector-state` in your Apify account). The next run with the same `stateName` delivers a website again only when a technology was added or removed; websites with the same stack are skipped and not charged. A version change alone (WordPress 7.1 to 7.2) does not count as a change. The first run delivers every website it can read. Use a different `stateName` for each list so they keep separate memories. **Notification when the run ends.** Put a webhook address in `notifyUrl` and the actor sends one JSON POST with the number of delivered rows, links to the dataset (JSON and CSV) and the run. It works with Slack and Discord incoming webhooks (the message is in `text` and `content`), with Make, n8n and Zapier catch hooks, and with your own endpoint. By default it is sent only when at least one row was delivered; `notifyWhenEmpty` sends it every time. **Schedules.** Create a schedule in Apify Console (daily, weekly, monthly or cron) with `onlyNew` on, and you get a feed of the websites in your list that changed their stack, for the price of those rows only. **Integrations.** Send the results to Make, n8n, Zapier, Google Sheets, Slack, Google Drive, Airtable or any webhook from the Integrations tab of the Actor, with no code. **API, SDKs and AI agents.** Every run is available through the Apify API and the official JavaScript and Python clients; the Actor can also be called by AI agents through the Apify MCP server. The example input in the API tab is a working call. ### Use cases - **Lead lists by platform:** from a list of shop domains, keep the ones on Shopify, WooCommerce or Magento, or the ones without a consent tool, a live chat or an e-mail marketing tool, and sell to exactly those. - **Agency and SaaS prospecting:** find the websites that use a competitor's product (a chat widget, a rating widget, an A/B testing tool) and offer yours. - **Competitor monitoring:** a weekly schedule with **Only new rows** tells you when a competitor adds a new analytics tool, payment provider or marketing platform. - **Market research:** the share of each CMS, platform or consent tool in a list of thousands of websites, from the `topTechnologies` of the run summary or the dataset. - **CRM enrichment:** add platform and marketing stack columns to company accounts before a campaign. - **Before scraping a shop:** check the platform first, then use the matching Rowcraft actor, such as the [Shopify Products Scraper](https://apify.com/rowcraft/shopify-products-scraper), the [WooCommerce Products Scraper](https://apify.com/rowcraft/woocommerce-products-scraper) or the [VTEX Products Scraper](https://apify.com/rowcraft/vtex-products-scraper). Ready-made examples, each with the input filled in (open one and press Start, or save it as your own task): - [E-commerce platform of a list of online stores](https://apify.com/rowcraft/website-tech-stack-detector/examples/ecommerce-platform-of-online-stores) - [Marketing tools of SaaS websites: analytics, pixels, chat](https://apify.com/rowcraft/website-tech-stack-detector/examples/marketing-stack-of-saas-websites) ### What this actor does not do - Collect contacts: no e-mail addresses, phone numbers, names of people or social profiles, and no page text apart from the title. - Crawl a website: only the home page is read, never other pages, the shop, the checkout or the sitemap. - Use BuiltWith or Wappalyzer data: no third-party database is queried or copied; every detection comes from the page read during your run. - Return history: each row is the stack seen at the time of the run; for changes over time use **Only new rows** on a schedule. - Run JavaScript, log in, accept cookie banners, use proxies or solve CAPTCHAs: websites that answer with an anti-bot page are reported as blocked and not charged. ### Limits and fair use - **One request per second** by default (minimum 250 ms). A website takes two to four requests: robots.txt, the home page and any redirects. In our test runs that came to about three seconds per website, roughly 1,200 websites an hour. - **What is visible on the first load only.** The actor reads the HTML and headers of the home page without running JavaScript. Tools that are added later by a tag manager, after cookie consent, on scroll or only on other pages (the checkout, a contact page) are not seen. - **Anti-bot pages.** Websites behind a bot challenge (Cloudflare, Akamai, DataDome and similar) are reported as `blocked` and not charged. In our tests 38 of 198 websites, mostly large brands and retailers, answered with an anti-bot page. After 10 blocked websites in a row the run stops and says why in the run summary, because the rest of the list would most likely be blocked too. - **robots.txt is obeyed** for every address the visit touches, including redirect targets. If robots.txt disallows the home page the domain is `robots_disallowed`; if robots.txt answers with a server error the site is not read, as the robots.txt standard (RFC 9309) requires. - **Page size:** the first 2 MB of a home page are read; larger pages are cut there and counted in the run summary. - **Up to 100,000 domains per run.** The run stops 90 seconds before its timeout with the summary, the coverage and the **Only new rows** memory saved; for long lists raise the timeout or split the list. ### Data source and licence The data is what each website sends to every visitor: the response headers, the names of the cookies it sets, and the HTML of its home page. The actor reads that page once, as a browser does on the first visit, after checking robots.txt, and keeps only the names of the technologies, their versions and short evidence (a header name, a script address, a code fragment of a few words). The page text, images and cookie values are not stored or delivered. The detection rules are Rowcraft's own work, written and tested on real websites; they are not derived from Wappalyzer, webappanalyzer, BuiltWith or any other fingerprint database. Rowcraft is independent: this actor is not provided, endorsed or authorised by the websites it reads or by the makers of the technologies it names. Product names and trademarks belong to their owners and are used only to say which product a website uses. ### Privacy: no personal data Rowcraft actors are built not to collect personal data: - Only the home page of a website is read, and the row holds technology names, categories, versions and evidence, plus the page title and language. - Cookie values are never read or stored, only cookie names (such as `_shopify_essential`), which identify a product, not a person. - An e-mail address or phone number inside the page title or a code fragment is removed, and a script address that would contain one is reduced to its host name. - The actor sends no cookies, fills no forms and never logs in. You are responsible for using the data in line with the law that applies to you. ### Other Rowcraft actors All Rowcraft actors read official or public sources, deliver flat rows without personal data and support only-new runs and notifications: -

On the 126 home pages used to write them the actor makes 818 detections, each checked by hand against its evidence; the false positives found there (for example the letters "vtex" inside minified code of a WooCommerce shop) were fixed. On 29 further websites that were not used to write the rules, all 162 detections named a technology the page really loads; one version was wrong (a cache-busting number read as the jQuery version) and has been fixed. Expect some technologies to be missed, and check any detection against its evidence. **Why does a tool I know the website uses not appear?** The actor sees what the home page sends on the first load, without running JavaScript. Tools injected later by a tag manager, after cookie consent, or present only on other pages are not visible there. A tool can also be outside the 336 the actor knows. **Why is the result empty?** Every domain in the list could not be read, or was skipped. The `COVERAGE` record gives the reason per domain: an anti-bot page (`blocked`), robots.txt (`robots_disallowed`), no website at that address (`not_found`), an invalid entry or a connection problem (`error`). With **Only new rows** on, websites whose stack did not change are skipped too. Nothing is charged for those, apart from the start event. **Is it legal?** The actor reads one public page per website, the home page any visitor gets, obeys robots.txt and collects which tools the page loads, not personal data or page content. Whether and how you may use the results (for example for marketing) depends on the law that applies to you. **Does it collect personal data?** No personal data: no e-mail addresses, phone numbers, people's names or cookie values. See the Privacy section. **Do I pay for websites that block the actor?** No. Blocked, robots-disallowed, not found and invalid entries are never charged, and neither are duplicates in your list. **Does it show versions?** When the page shows them: a generator tag (WordPress 7.2, Elementor 4.3.2) or a version in a file name (jQuery 3.7.1). Otherwise `version` is null. **Can I give full URLs instead of domains?** Yes. The address is reduced to its website and only the home page is read; `inputUrl` keeps what you gave and `url` shows the home page that answered after redirects. **How does Only new rows work here?** The actor remembers the set of technologies of each website delivered to you. The next run with the same state name delivers a website only when a technology was added or removed, so a weekly schedule costs only the websites that changed. ### Support and reviews **Problems, missing fields, questions:** open an issue on the **Issues** tab of this Actor. We answer within one working day and fix confirmed bugs in the next release; the changelog lists every change. If this Actor saved you time, a short review on its page helps other users find it and helps us keep improving it. # Changelog This Actor's version history is a separate document: https://apify.com/rowcraft/website-tech-stack-detector/changelog.md # Actor input Schema ## `domains` (type: `array`): Websites to check, one per line: a domain (example.com) or an address (https://www.example.com/shop). Only the home page of each site is read. Duplicates and invalid entries are skipped and never charged. ## `maxItems` (type: `integer`): Stop after this many rows are delivered. 0 = the whole list. ## `onlyNew` (type: `boolean`): Remember the rows already delivered to you (in a key-value store in your Apify account) and deliver only rows that appeared since the last run with the same state key. The first run delivers everything that matches; later runs cost only the new rows. Ideal for schedules. ## `stateName` (type: `string`): Name of the memory used by "Only new rows". Use a different name for each schedule or search (for example `stockholm-python`) so they do not share one memory. ## `notifyUrl` (type: `string`): A webhook address that receives one JSON POST with the number of new rows and links to the dataset: a Slack or Discord incoming webhook, a Make, n8n or Zapier catch hook, or your own endpoint. The message is also in the `text` (Slack) and `content` (Discord) fields. ## `notifyWhenEmpty` (type: `boolean`): By default the notification is sent only when at least one row was delivered. ## `requestIntervalMs` (type: `integer`): Default 1000 ms (one request per second). Each domain takes two requests: robots.txt and the home page (plus redirects). Minimum 250. ## Actor input object example ```json { "domains": [ "landyachtz.com", "deathwishcoffee.com", "wordpress.org" ], "maxItems": 0, "onlyNew": false, "stateName": "default", "notifyWhenEmpty": false, "requestIntervalMs": 1000 } ``` # Actor output Schema ## `results` (type: `string`): One row per website with its technologies, in the default dataset (JSON, CSV, Excel and other formats via the dataset API). ## `runSummary` (type: `string`): Counts, the most frequent technologies, warnings and why the run stopped (RUN_SUMMARY record in the default key-value store). ## `coverage` (type: `string`): One line per domain you asked for: ok, blocked, robots_disallowed, not_found, error or not_checked, with the reason (COVERAGE record). # 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 = { "domains": [ "landyachtz.com", "deathwishcoffee.com", "wordpress.org" ] }; // Run the Actor and wait for it to finish const run = await client.actor("rowcraft/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 📖?

Go to → https://docs.apify.com/api/client/python/docs/quick-start ``` ## CLI example ```bash echo '{ "domains": [ "landyachtz.com", "deathwishcoffee.com", "wordpress.org" ] }' | apify call rowcraft/website-tech-stack-detector --silent --output-dataset ``` ## MCP server setup ```json { "mcpServers": { "apify": { "type": "http", "url": "https://mcp.apify.com/?tools=fetch-actor-details,rowcraft/website-tech-stack-detector" } } } ``` The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer ` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations). ## OpenAPI specification Download the OpenAPI definition: https://api.apify.com/v2/actors/dORSgiEJeuU5DzgKg/builds/2NW0Ac9QNFVGsb9b9/openapi.json
