What it really isBuiltWith — web technology profiler and B2B sales intelligence platform.
Our takeBuiltWith is the go-to platform for revealing any website's full technology stack — CMS, analytics, ad networks, payment gateways, hosting, and more — then turning that data into targeted prospect lists.
The Chrome extension is a free add-on, but the core product is a SaaS lead-gen and market-intelligence platform. Pricing is confirmed at $295/mo (Basic) through $995/mo (Team), with a niche $144/yr 'Advanced' plan for detailed single-site lookups only.
Why we rate itNo other tool matches BuiltWith's breadth of technology detection — 50,000+ technologies tracked — combined with the ability to export filtered prospect lists directly into a CRM.
For tech-stack-based prospecting, it is the category standard.
The catchPricing starts at $295/mo, making it expensive for solo users or small teams; the free tier is limited to single site lookups with no list-building or export capabilities.

Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: free site lookup is instant; paid list exports are available within minutes of subscribing.
  2. Scale breakpoint
    Basic plan caps at 2 technology searches/month — teams that need broader prospecting quickly hit the ceiling and must jump to Pro ($495/mo).
  3. Walled garden
    Moderate: CRM integrations and CSV exports exist on all paid plans, but the underlying dataset and list-filtering logic live entirely within BuiltWith.
Still a fit?
If none of these block you, try it on the official site.
