Overview

BuiltWith’s dataset covers 127,671 web technologies and more than 370 million active domains, with over 18 years of technology-usage history. That breadth gives competitive researchers and sales teams a way to examine adoption across the web, rather than just inspect individual sites. Its public intelligence is collected from accessible websites and observable internet signals, not password-protected or restricted systems.

BuiltWith says it is PCI DSS monitored by SecurityMetrics, and that its data centers are certified to ISO/IEC 27001, SOC 1 Type II and SOC 2 Type II. Servers processing personal data are HSTS enabled. Telephone and email support are available seven days a week.

Key features

Technology research and lead generation

Technographic filters let users find sites by the technologies they use. Future Customers applies technology overlap to recommend websites as possible sales leads, making BuiltWith a natural fit when a web stack is a useful qualification signal. It is less suited to prospecting that does not depend on technology adoption.

Ecommerce research and exports

Users can identify ecommerce sites and products, filter reports by category, region and technology, then export results. Uploaded website lists can also be analyzed, with report metadata and technology-usage matrices exported to Excel or CSV. This combination is useful for research workflows that move from discovery to spreadsheet analysis, though the plan limits matter for teams that need frequent or large-scale access.

Integrations and developer access

CRM integrations include Salesforce, HubSpot, Pardot, Zoho CRM, Close.io and Microsoft Dynamics 365. The API provides XML and JSON feeds, and BuiltWith says AI agents can connect through APIs, MCP tools and AI-ready SDKs. Extensions are available for Chrome, Firefox and Edge. These options give teams several ways to bring its data into existing workflows, but API usage is quota-based on paid plans.

Pricing

BuiltWith is freemium. The free plan costs 0.00 USD per free and allows 10 detailed lookups per day; individual website lookups are free forever. That is enough for occasional checks, but not a substitute for sustained research or high-volume prospecting.

Advanced: 144.00 USD per year, billed with a one-year minimum. It offers unlimited detailed lookups and a single-login dashboard. This is the lowest-cost paid option for an individual who mainly needs broader lookup access; it does not include the stated API credits or retail-report limits of the higher plans.
Basic: 295.00 USD per month, with a one-month minimum. It includes 2 technologies, 2 keywords, 2 retail reports, 1 system login, 2,000 API credits per month and 300,000 synced leads or contacts. The narrow research limits make it a costly fit unless those allowances closely match a small workflow.
Pro: 495.00 USD per month, with a one-month minimum. It removes the technology, keyword and retail-report caps, while retaining 1 system login; it includes 20,000 API credits per month and 300,000 synced leads or contacts. It suits a solo operator needing much broader research or API use, but not a team that needs multiple logins.
Team: 995.00 USD per month, with a one-month minimum. It includes unlimited technologies, keywords and retail reports, unlimited logins, 100,000 API credits per month and 300,000 synced leads or contacts. It is the clearest fit for a group sharing the platform and needing the largest stated API allowance.

Monthly plans have a one-month minimum and yearly plans a one-year minimum; plans can be canceled at any time. The annual commitment on Advanced lowers the entry price but locks in a longer minimum term, while the monthly plans carry a much higher ongoing cost. Basic and Pro both limit access to one login, so they are not team plans despite their broader research quotas.

Platforms

BuiltWith is available on the web, through an API and as browser extensions for Chrome, Firefox and Edge. Its XML and JSON feeds and AI-agent access support developer workflows alongside browser-based research.

Who it's for

BuiltWith is a strong match for sales and research teams targeting companies by web technology, ecommerce researchers comparing adoption, and developers who need technology data through an API. The free allowance works for occasional site checks. Teams that need modest recurring use should weigh the narrow Basic quotas against its monthly price, while buyers needing multiple logins must look beyond Advanced, Basic and Pro to Team.

Pros and cons

Pro: Broad coverage—127,671 technologies, more than 370 million active domains and over 18 years of history—supports both site-level research and wider adoption analysis.
Pro: Ecommerce discovery, technology-based lead recommendations, list analysis and exports connect research to prospecting and spreadsheet workflows.
Pro: CRM integrations, API feeds, MCP tools and browser extensions provide several routes into existing sales or developer processes.
Con: Free detailed lookups are capped at 10 per day, limiting the free plan to light use.
Con: Basic costs 295.00 USD per month while limiting users to 2 technologies, 2 keywords and 2 retail reports; those caps may constrain the very research it is meant to support.
Con: Advanced requires a one-year minimum, and the lower-priced paid tiers do not offer multiple logins.

Alternatives

Choose Wappalyzer if its free plan’s 50 technology lookups and 50 email verifications per month, five website alerts and sample lead lists better match a smaller workflow. Grizz Technographics is worth considering for limited sample tech-stack and company data; its Premium plan has custom pricing. BuyerCaddy offers a free single-user plan with 1,000 tokens, rollover and its user platform and CoPilot, which may suit a solo user seeking those tools.

NerdyData provides a free account with reports capped at 500 rows and a free API account, a more bounded option for users whose reports fit that limit. Pursued.io has a free plan with 50 credits and one team member, making it an option for a small starting workflow. TechnologyChecker offers 100 free lookups per month, six months of historical data and single-result CSV export; its stated free allowance may suit lighter research. B2BEnrich offers 50 free monthly credits for person and company enrichment, a better fit when those enrichment tasks are the priority. StackDetect provides 50 free monthly technology lookups and sample lead lists for users comparing a small volume of lookups.

For broader category browsing, explore Technographic Data Software, Lead Enrichment Software, Company Databases, Sales Prospecting Software, Account Enrichment Software and B2B Contact Data Providers.

Verdict

Choose BuiltWith if your work depends on broad technology-adoption data, ecommerce research or leads defined by website stack. Its coverage and mix of analysis, exports and integrations make that combination compelling. Look elsewhere if you need only occasional lookups, multiple seats on a lower-cost plan or broad recurring use without a substantial monthly spend.
