Wappalyzer
Checking website technology and building targeted lists
Wappalyzer identifies website technologies and supports lead lists, alerts and enrichment. It is useful for a quick technology check or a repeatable workflow built around a specific software category.
Our research notes
A single-site lookup can help prepare an account conversation. For a larger list, combine technology filters with your own fit criteria and confirm the detections that make an account worth contacting.
Why choose it
The free lookup allowance supports small research tasks, while paid plans add lists, API access and CRM workflows. This gives teams a path from manual checks to larger-scale use.
What to consider
A detected script or platform does not describe a company’s full internal stack. Included API credits expire, so compare expected usage with the plan and credit terms.
Pricing
Free accounts include 50 technology lookups per month, five website alerts and sample lead lists. Paid Pro, Business and Enterprise plans change list access, users, lookups and API allowances. Plan-included API credits expire after 60 days; purchased bundles have separate terms.
Pricing checked 28 October 2026. Billing terms, taxes, usage limits and add-ons can change. See the vendor's pricing. (opens in a new tab)
