Where does BuiltWith fit in a GTM engineering stack?
BuiltWith is the technographic layer in a GTM engineering stack: it decides which accounts qualify by the tools they run, and flags when an account adds or drops a technology.
- 1BuiltWith's Lists API pulls every domain running a target or competitor technology
- 2Clay imports the domains and runs Find Technology Stack to score each account on stack fit
- 3A contact provider such as Prospeo or FullEnrich finds buyers at qualifying accounts
- 4Messaging references the detected tool, and contacts route to Smartlead or lemlist
- 5Change API or Slack alerts re-trigger outreach when an account removes the competitor

Who is BuiltWith best for?
A good fit if you
- Teams whose ICP is defined by a technology, such as 'Shopify Plus stores' or 'sites running a competitor's tag'.
- Competitive displacement campaigns that need to spot when an account adds or drops a tool.
- Clay users who want a stack column on each account, since Clay's BuiltWith action returns technology count, names and descriptions.
- Ecommerce-focused sellers: BuiltWith says it tracks 2,500+ ecommerce technologies across 26 million+ ecommerce sites.
Look elsewhere if you
- Finding EU contacts: BuiltWith says it no longer provides personal information of people in the EU without consent, so pair it with a contact provider.
- Back-end or internal tools that leave no trace on a public website, such as a CRM or data warehouse, which front-end detection cannot see.
- Occasional users, since the cheapest plan is $295 a month and Basic is limited to 2 technologies and 2 keywords.
- Teams wanting firmographic or funding depth as the main dataset; BuiltWith's core is technology usage.

BuiltWith FAQs
How accurate is BuiltWith technographic data?
BuiltWith detects technologies from what a website exposes publicly, such as scripts, tags and headers, so it is strongest for front-end, marketing and ecommerce tools. Tools that leave no footprint on the website, like most CRMs or internal software, are hard for any website profiler to see. Spot-check a sample of accounts you know before building a campaign on it.
Can BuiltWith find companies using a competitor's product?
Yes, that is BuiltWith's core use: the Lists API and LeadsDiscovery return every site detected running a given technology. Each Lists API page returns up to 500 records for 1 API credit. Pro and Team plans allow unlimited technology reports; Basic is limited to 2.
Does BuiltWith provide contact details?
BuiltWith includes limited business contact context from public websites, but says it does not provide personal information for people in the EU or California. For named buyers with verified emails, run its account lists through a contact provider such as Prospeo, FullEnrich or a Clay waterfall.
Is BuiltWith free to use?
BuiltWith says individual site lookups on its website are free forever. Lead lists, exports, CRM sync and API credits need a paid plan from $295 a month, or a $99 pay-as-you-go pack of 2,000 API credits that does not expire.
How do I use BuiltWith in Clay?
Clay's BuiltWith integration adds a Find Technology Stack column that takes a website and returns the technologies detected, their count and descriptions. You can run it on Clay credits or connect your own BuiltWith account. Filter or score rows on that column before spending credits on contact enrichment.
