Alpha Crawler
What Alpha Crawler is
Alpha Crawler is a technical SEO crawler available as self-hosted software or a web service. It audits site structure, metadata, schema markup, AI search visibility, and site performance. The free crawler handles up to 10,000 pages per audit and allows crawl depth from 1 to 10 levels. Its issue log groups findings by impact, including duplicate titles, missing H1s, orphan pages, sitemap gaps, and render-blocking resources. JavaScript-rendered sites can be included when rendering is enabled. Schema tools show site-wide distribution and validate JSON-LD on individual URLs, including entity-property checks. Read-only Google Search Console access adds page-level clicks, impressions, and ranking data. Reports can be exported to CSV and XLSX, with PDF exports also listed. AI summaries run on demand using your Gemini API key, stored locally in the browser. Robots.txt is respected automatically. The free plan includes full reports and exports. An agency plan adds expanded limits, scheduled monitoring, multi-client workflows, client-ready reports, AI insights, and priority support.
