crawlie

The fast, free, open-source technical SEO + GEO crawler — CLI and MCP server. By Spronta.

npm i -g crawlie

This installs two commands (the right prebuilt binary for your platform is pulled in automatically as an optional dependency — no download script, nothing to unblock):

• crawlie — crawl & audit any site from the command line
• crawlie-mcp — a Model Context Protocol server so agents can run audits

crawlie crawl https://example.com --format pretty     # crawl a whole site
crawlie audit https://example.com/pricing             # audit one page
crawlie crawl https://example.com --format html -o report.html
crawlie explain geo-not-answerable                    # why a finding matters

Use with agents (MCP)

// claude_desktop_config.json (or any MCP client)
{
  "mcpServers": {
    "crawlie": { "command": "crawlie-mcp" }
  }
}

Tools: crawl_site, audit_url, audit_urls, explain_issue, list_rules, list_reports, get_report.

Supported: macOS (arm64/x64), Linux (x64), Windows (x64). Other platforms: build from source. The desktop app (signed .dmg) is a separate download on Releases.
