Diffbot vs Webz.io: overview
Diffbot
Diffbot combines automatic web page extraction (Article API, Product API, Discussion API) with a continuously-updated knowledge graph of 10 billion+ entities including companies, people, products, and events. Its Knowledge Graph Search API queries this structured dataset using natural language rather than keywords, enabling precise entity-level retrieval beyond what SERP APIs provide. Diffbot was founded in 2010 by Mike Tung at Stanford University and is headquartered in Menlo Park, California. It uses computer vision and machine learning to extract structured data from any web page without custom selectors. Clients include Snapchat, DuckDuckGo, Cisco, and Goldman Sachs (per company website; independently unverifiable).

The News API covers 240+ languages and 50+ topics. The Cyber API provides access to paste sites, hacker forums, and dark web marketplaces for threat intelligence use cases. Webz.io was founded in 2015 and is headquartered in Tel Aviv, Israel. It serves government agencies, financial institutions, and Fortune 500 brands (per company website; independently unverifiable).
