Wappalyzer Review

Depends

Should I use Wappalyzer?

Wappalyzer helps sales and GTM teams build technographic prospect lists, enrich CRM records, and monitor competitor installs with data from millions of websites. - wappalyzer.com

· 1 month ago

Buy if your GTM team targets prospects by tech stack weekly and will actually use the lists or APIs. Skip if you want occasional lookups or simple pricing — the free extension and open-source tools already cover that.

Gotchas - check before you buy

Pricing called "a mess" by third-party reviewers — audit plan limits before committing.

Open-source clones appeared after pricing changes — terms may shift again; avoid long commitments.

low

Guess: paid lookups are credit-based; the free tier won't cover list building at scale.

Vendor security page failed to load during review — request docs during procurement.
