Wappalyzer vs. BuiltWith

Looking for a BuiltWith alternative? Wappalyzer is cheaper and more accurate.

Wappalyzer and BuiltWith are technology profilers that provide tools for lead generation, market research and business intelligence. The two companies share common background: both are Australian-based and founded at around the same time (2007-2008).

The commonalities don't end there. With either provider, you can:

  • Uncover the technologies that power any given website.
  • Create lists of websites and contacts that use certain technologies.
  • Deep-dive into technology trends market shares.
  • Enrich your own data with technology information.
  • Monitor your competition's technology stacks.

There are of course differences, some of which we'll highlight here.

Data accuracy

Consistent customer feedback confirms that Wappalyzer is the most accurate technology profiler. Wappalyzer's data is updated daily, ensuring only actively visited websites are included in technology lookups and lead lists. The focus is on quality, not quantity.

Every website tracked by Wappalyzer is reverified at least once a month. BuiltWith apears to do this roughly once a quarter, often including stale data in reports.

Thanks to an active community of developers, Wappalyzer's crowd-sourced technology fingerprints are constantly reviewed and improved and technologies are added daily.


Wappalyzer's data is largely sourced from a browser extension, supplemented by in-house crawlers. The browser extension is used by 2M users on a daily basis (many times more than BuiltWith), providing a large sample size to measure website traffic and track live websites. This method allows scanning of pages that crawlers typically can't reach, such as shopping carts, checkouts and sections behind a login.

BuiltWith pricing

BuiltWith charges a high monthly price, starting at $295 for the Basic plan, limiting access to two technologies and only including 2,000 technology lookups. API credits and multiple logins are only included if you upgrade to their $995 Team plan.

Wappalyzer pricing

Wappalyzer offers lower prices and includes a greater number of technology lookups at each plan tier.

Additionally, API credits, multiple logins and integrations are included in our mid-tier Business plan, whereas they are only available in BuiltWith’s highest tier.
