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"] }
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.
