BuiltWith Alternative: Detect Any Website's Tech Stack via API (No Subscription)

BuiltWith is the go-to for "what is this site built with" — but its paid plans start around $295/month, which is a lot if you just need to enrich a lead list or check a few hundred domains now and then. If you don't need an enterprise subscription, here's a pay-as-you-go alternative that returns the same kind of data via a simple API.

What you actually need

Most people reaching for BuiltWith want one of three things:

  • Sales intelligence — "does this company use Shopify / HubSpot / Salesforce?"
  • Lead scoring — filter a list by the tech a prospect runs
  • Competitive research — see a competitor's analytics, CMS, and hosting

For all of these, you need to point a tool at a list of domains and get back the technologies — not pay for a yearly seat.

The alternative: Website Tech Stack Detector

The Website Tech Stack Detector (and its sibling Tech Stack Detector) on Apify detect 100+ technologies on any site — frameworks, CMS, analytics, hosting, payment, marketing tools — and return clean JSON. You pay per site checked, with no monthly subscription.

{ "urls": ["https://example.com", "https://shopify-store.com"] }
Enter fullscreen mode Exit fullscreen mode

Output (per site): detected technologies grouped by category, plus the domain and a success flag — ready for a spreadsheet, CRM, or your own scoring model.

BuiltWith vs. pay-per-use detector

BuiltWith (paid plans) This detector
Pricing Subscription (~$295+/mo) Pay per site, no subscription
Best for Large, ongoing programs Lists, enrichment, occasional checks
Access Web app + API (higher tiers) API + no-code UI out of the box
Output Reports Clean JSON / CSV / Excel
Lock-in Annual plans None

If you run BuiltWith daily across millions of domains, their subscription may be worth it. If you enrich lists or check domains on demand, pay-per-use wins.

Use cases

  • Outbound sales — find every prospect on Shopify/Webflow/HubSpot before you pitch.
  • Lead enrichment — append tech stack to a CRM list in bulk.
  • Competitive & market research — map what tools a segment uses.
  • Recruiting/agencies — qualify clients by their stack.

FAQ

Is there a free or cheaper BuiltWith alternative? Yes — a pay-per-use detector like the one above avoids BuiltWith's monthly subscription; you only pay for sites you check.

Does it detect the same technologies? It covers 100+ common technologies across frameworks, CMS, analytics, hosting, payments, and marketing tools.

Can I check a bulk list of domains? Yes — pass an array of URLs and get one structured record per site.

Do I need an API key? No — run it via API or the no-code UI.


Need it for a list of domains? The Website Tech Stack Detector checks them in one run — no subscription, just pay per site.
