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.

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.

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 <TOKEN> with your Apify API token.

Run synchronously and get dataset items in one call:

curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~website-tech-stack-scraper/run-sync-get-dataset-items?token=<TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"websites":["shopify.com","wordpress.org"],"maxWebsites":10}'

Start a run asynchronously:

curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~website-tech-stack-scraper/runs?token=<TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"websites":["acme.com","globex.com","initech.com"],"maxWebsites":50}'

Apify CLI:

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:

# JSON
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&clean=true&format=json"

# CSV
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&clean=true&format=csv"

# Paginate large datasets
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&offset=1000&limit=1000"

<DATASET_ID> 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 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.
