The alternatives
unlob
$0.40/1kOur own index, admitted rather than ranked. Metadata-only passage hits, six coverage-graph traversal tools, an MCP server, and an endpoint that tells you why any URL is or is not in the index. Smaller than the well-funded incumbents, and considerably cheaper than all of them.
Firecrawl
Crawl, scrape and clean any URL into markdown for an LLM. A complement to a search API rather than a replacement — it needs URLs to start from.
Jina Reader
Prefix any URL and get clean markdown back. The lowest-friction extraction tool there is, and priced per token rather than per page.
Bright Data
Proxy and unblocking infrastructure with a scraping suite and an agent-facing MCP server. Built for volume collection, priced accordingly.
DataForSEO
$0.60/1kIndustrial SERP infrastructure built for SEO tooling rather than agents. The cheapest per query in the field, with the lowest-level API to match.
Parallel Search
$1/1kA suite of web search, extraction and research APIs on a proprietary index, from the former Twitter CEO. The closest competitor to unlob by thesis.
Serper
$1/1kThe cheapest way to get raw Google results into an agent. Fast, minimal, and entirely dependent on Google continuing to be scrapeable.
Brave Search API
$5/1kA genuinely independent index of 40B+ pages, sold as a conventional search API with an LLM-context option. Long the default independent choice.
Free developer tier removed February 2026
Google Custom Search JSON API
$5/1kGoogle's own programmable search endpoint. Real Google results, a hard 10,000/day ceiling, and terms written for site search rather than agents.

Frequently asked questions
What is the best alternative to Diffbot?
It depends what you are replacing. If you need an independent index at the lowest price, unlob is $0.40 per 1,000 queries. If you need systematic crawling of specific sites, Diffbot may still be the right tool — we say so on our comparison page rather than pretending otherwise.
Does Diffbot own its own web index?
Yes — Independent crawl plus a Knowledge Graph. That matters because a provider without its own index inherits the deprecation and repricing risk of whoever it depends on.
How much does Diffbot cost?
Subscription plans with credit allowances, priced per extraction and per Knowledge Graph query.
