What does Klazify do?
Klazify is a domain intelligence platform that lets you look up any website and get back a detailed profile. Enter a URL and you instantly see the site's IAB content category with a confidence score, the company behind it (name, HQ, employee count, revenue range), what technologies it uses (CMS, analytics, CDN — over 150 techs detected), traffic metrics like global rank and monthly visits, and even a list of similar domains and competitors. It's basically a one-stop lookup for everything you'd want to know about a website.
The platform comes as both a web interface and a RESTful API with 10 endpoints. The web version is handy for quick checks — you can browse by industry categories (Home & Garden, Automotive, etc.) to find sites in a specific vertical. But the real power is in the API. Klazify returns clean JSON responses with fields like category paths, confidence scores, logo URLs, social media links, and company details. It also offers a Logo API that serves up-to-date company logos in multiple sizes, and batch CSV enrichment for processing lists of domains. Developers can start integrating in minutes after grabbing an API key.
Klazify is built for data teams, sales prospectors, ad tech professionals, and anyone who needs to automate web research at scale. Advertisers use it for contextual targeting and brand safety — the IAB v3 classification covers 620+ categories. Sales teams filter prospects by industry, country, and tech stack to find the right leads. Competitive analysts use the similar domains and traffic data to benchmark companies. If you've ever needed to understand what a website is about, who runs it, what tech it uses, and how popular it is, Klazify gives you that info faster than manual research.
