Webz.io vs Diffbot: overview
Webz.io
Webz.io started in 2014 as Webhose.io, later rebranded, and is headquartered in the Tel Aviv area under co-founder and CEO Ran Geva. Its News API claims 3.5 million new articles a day from 350,000+ sources in 170+ languages (per company website; independently unverifiable), and the same company sells blog, forum, review and dark-web feeds. Queries use a field syntax such as title:, language: and sentiment:, and anything older than 30 days goes through a separate archive that reaches back to 2008. Every account receives $5 of free credit a month, with pay-as-you-go and custom high-volume contracts above that.
Diffbot
Diffbot was founded in 2008 by Mike Tung and is based in Menlo Park, California, with an estimated 30–40 employees. It uses computer vision and NLP to extract structured articles from any web page, and its Knowledge Graph links articles to organisations, people and topics so it can be queried as a news source. A free plan includes 10,000 credits at five calls a minute, the Startup plan costs $299 a month for 250,000 credits, and exporting one Knowledge Graph entity costs 25 credits. Teams that want to assemble their own news collection get more from it than teams wanting a ready-made feed.
