BuiltWith
Technology profiler that reveals what software stack any website runs, with AI-powered lead lists by tech usage.
What it does
BuiltWith is a technology profiling and market intelligence platform that identifies the technology stack powering any website - CMS, e-commerce platform, analytics tools, ad tech, CDN, payment processors, and hundreds of other technology categories. Its AI capabilities include AI-powered technology change detection that alerts users when target websites add or remove specific technologies, predictive technology adoption modeling that identifies companies likely to purchase complementary tools, and AI-enriched lead list generation that exports contact data for companies using specific technology combinations. Sales and marketing teams use BuiltWith for technology-based prospecting - targeting companies using a competitor's product, identifying e-commerce merchants on a specific platform, or finding companies likely to need their solution based on current tech stack.
Why AI-ENHANCED
BuiltWith is an established technology intelligence platform that has integrated AI technology change detection, predictive adoption modeling, and AI-enriched prospecting into a mature website technology profiling product.
Best for
Individual sales reps and consultants use BuiltWith's free tool to research prospect technology stacks - knowing what software a target company runs before an outreach call.
Small marketing and sales teams use BuiltWith for technology-based prospecting - building lead lists of companies using competitor products or target platforms for highly qualified outbound campaigns.
Growing B2B software companies use BuiltWith for market intelligence - understanding technology adoption trends, tracking competitor install base changes, and identifying the highest-fit prospects by tech stack.
Mid-market sales and revenue ops teams use BuiltWith API for CRM enrichment - automatically tagging accounts with technology usage data to enable technology-based sales plays and prioritization.
Enterprise sales intelligence teams use BuiltWith for systematic account intelligence - technology profiling enriching ABM target lists and AI change alerts triggering outreach when prospects adopt or drop relevant technologies.
Limitations
BuiltWith detects technologies from public-facing website signals — technologies used internally or behind authentication (backend databases, internal tools) are not detectable, and some front-end technologies may be obfuscated.
BuiltWith's contact data for lead lists is aggregated from various sources and varies in accuracy — email verification and CRM enrichment tools should be used to validate contacts before outreach.
The free BuiltWith tool allows individual website lookups but bulk lead list exports, technology trend data, and API access require paid plans — the free tier is mainly useful for one-off research.
Alternatives by segment
Free for individual lookups. Basic at $295/month. Pro at $495/month. Team at $995/month. API access additional. Annual billing available. Includes technology trend data and bulk exports on paid plans.
