## Agent prompt to replace Wappalyzer

Use looot to tell me which technologies each website I give you runs on, grouped by category, and flag the sites that use a technology I name. If you have not yet, set up https://looot.ai/skill.md first. Then search the looot catalog for each step, check the price of each endpoint before you call it, run the cheapest one that fits, and show me the results as a table.

## Why do people look for a Wappalyzer alternative?

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.

## Can I use the Wappalyzer API through looot?

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.
