Tavily vs Diffbot: overview
Tavily
Tavily, founded by CEO Rotem Weiss, is a search API designed to be called by LLM agents, and its topic=news mode limits results to recent coverage with extracted text ready for a prompt. It is the quickest way on this list to give a LangChain or LlamaIndex agent a news tool, since both frameworks ship Tavily integrations. Nebius, the Nasdaq-listed AI cloud company, agreed to buy Tavily in February 2026 (Bloomberg put the price at $275 million) and later said the deal had closed, keeping the brand and pricing. Credits cost about $0.008 each on pay-as-you-go, a basic search uses one and an advanced search two, and 1,000 credits a month are free. Because it is a search tool, there is no archive, source list or clustering to work with.
Diffbot
Diffbot, founded by Mike Tung in 2008 and based in Menlo Park, California, has an estimated 30–40 staff. Point its Article API at any news URL and it returns title, author, date and clean text without a site-specific parser, and Crawlbot can follow a list of publishers you choose. Its Knowledge Graph links articles to companies, people and topics, so it can also be queried as a news source. The free plan includes 10,000 credits at five calls a minute, Startup costs $299 a month for 250,000 credits, and each exported Knowledge Graph entity costs 25 credits. It works best when you want to build your own news collection from chosen sites.
