What do people ask about Wappalyzer alternatives?

API access sits behind a plan. Wappalyzer says you need a plan for lead lists, APIs and CRM integrations, credits included in plans expire after 60 days, and a free account gets 50 lookups each month (https://www.wappalyzer.com/pricing/, read 2026-11-03). An agent that looks up a few hundred domains wants to pay per lookup instead.

Wappalyzer's lookup is listed in the looot catalog as an own-key endpoint: it runs on your own Wappalyzer key and plan. Without a Wappalyzer plan, use the paid tech stack job on the other providers in the jobs list.
