Crawler.sh is a fast, local-first web crawler and SEO & AEO analysis tool that runs from your terminal or a native desktop app. It crawls entire websites in seconds, performs 24 automated SEO checks on every page, extracts readable content as clean Markdown, and exports results to JSON, CSV, or Sitemap XML — all without sending your data to any external server.
Every page's main article content is automatically extracted and converted to clean Markdown. The tool includes word count, author byline, and excerpt for each page, making it easy to repurpose or archive web content.
Crawl any website while staying within the same domain. Built-in JavaScript rendering auto-detects and handles JS-heavy pages, and you can configure concurrency, depth limits, and polite delays between requests.
Each page is scanned for missing titles, duplicate meta descriptions, noindex directives, thin content, broken links, long URLs, and content freshness signals. Issues can be exported as CSV or human-readable TXT for your team.
Stream results as NDJSON during the crawl, or export to JSON arrays and W3C-compliant Sitemap XML. SEO reports export as CSV or TXT, giving you flexibility for any downstream workflow.
Crawl any website, find every issue, and export the data you need — all from your own machine.
This local-first approach means no data ever leaves your computer, making it ideal for sensitive or internal sites. The combination of fast crawling, automated SEO analysis, and clean Markdown extraction in a single tool eliminates the need to juggle multiple services. You get a complete pipeline from crawl to export without recurring subscription costs or API rate limits.
You need a privacy-respecting, all-in-one tool for crawling websites, running SEO audits, and extracting content — whether you're a solo developer automating workflows or an SEO team catching issues before they impact rankings. It's especially useful if you prefer working from the terminal or want a desktop app that keeps everything local.
