About
CrawlGraph helps SEO practitioners, indie founders, and researchers find domains linking to a website in Common Crawl's open hyperlink graph. A free web lookup shows five referring domains without signup. Paid access expands the result set, supports CSV and JSON exports, and compares a site with competitors to identify link gaps.
The public REST API includes a free monthly backlink lookup quota. The crawlgraph-mcp npm package and hosted MCP server expose backlink lookups, release comparisons, competitor gap analysis, outreach-target research, and release metadata to compatible AI clients. Results come from named Common Crawl snapshots, not a live crawl. CrawlGraph does not provide rank tracking, keyword research, PPC intelligence, or a full site-audit suite.
