CrawlGraph

CrawlGraph is a backlink-intelligence SaaS built on Common Crawl's open hyperlink graph (121.1M domains / 3.90B domain-level links), positioned as a low-cost alternative to Ahrefs, Moz, Semrush and Majestic. It offers referring-domain lookups with authority scoring, competitor gap analysis, warm outreach-target discovery, and cross-release change comparison. The product ships an unusually complete developer surface for a solo-operator SaaS: a public OpenAPI 3.1 contract, a self-serve free API tier (15 backlink calls a month, no card), a hosted remote MCP server whose tools publish both input and output schemas, an open-source local MCP package on npm, a published llms.txt, and open CC-BY study datasets. It is operated by Search Engine Wizards in Finland and priced as a one-time $99 lifetime licence rather than a subscription.

CrawlGraph publishes 1 API on the APIs.io network: V1 API. Tagged areas include SEO, backlink-intelligence, MarTech, Competitive Intelligence, and Web Data.

CrawlGraph’s developer surface includes documentation, API reference, getting-started guide, engineering blog, authentication, code examples, pricing, and 28 more developer resources.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/crawlgraph: open an issue to ask a question, or submit a pull request to add artifacts.
