Crawly review
A free crawler for deep technical audits, change detection, extraction, and AI-assisted workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Crawly is a free SEO crawler for SEO professionals, agencies, developers, and website teams. It identifies technical and on-page issues across metadata, headings, canonicals, robots directives, word counts, response times, broken links, redirects, status codes, external links, hreflang, structured data, and security headers. It also supports backlink and referring-domain analysis, XML sitemap generation, and local crawl-data storage. The product is available through web, macOS, and API access, with AI-assisted workflows through MCP integrations.
Crawly’s pricing is straightforward: the Free plan costs £0 forever. It includes unlimited URLs per crawl, all SEO issue types, crawl comparison, Claude Code MCP integration, XML sitemap generation, custom CSS extraction, and source-code search. There are no additional paid tiers presented in the published plan structure, so buyers can evaluate the complete listed feature set without comparing limits between packages. This makes the product a clear fit for teams seeking technical crawling without a recurring subscription tier.
Its strongest distinction is the combination of detailed crawling and workflow flexibility. Field-level change detection helps compare crawls, while CSS-selector and regex extraction supports targeted collection beyond standard issue reports. Structured-data, security-header, backlink, and sitemap features broaden the audit scope, and MCP support connects crawl data with Claude Code, Claude Desktop, Cursor, Codex, and Windsurf. Crawly should suit technical SEO work and developer-led audits; teams centered on keyword research, rank tracking, or competitor research should choose a tool built around those workflows instead.
