Key Features

  • High-speed site crawling: Crawls entire domains in seconds with configurable concurrency, depth limits, and polite delays so users can tune performance without hammering servers.
  • Content extraction to Markdown: Automatically isolates main article content on each page and converts it to clean Markdown, with word count, author byline, and excerpt for consistent downstream use.
  • Multiple export formats: Streams crawl results as NDJSON for pipelines, or exports as JSON arrays, Sitemap XML that follows W3C guidelines, and Markdown content archives.
  • Local-first, privacy-friendly design: All crawling and analysis happen on the user’s own machine, which is appealing for sensitive sites, pre-release environments, or proprietary content.

Pros

  • + Fast and configurable: High-speed crawling with fine-grained control over concurrency and depth suits everything from tiny blogs to large content sites.
  • + Great for AI and data workflows: Clean Markdown, NDJSON, and JSON outputs make it easy to plug website content into LLM pipelines, analytics jobs, or custom scripts.
  • + Local-first privacy: Keeping crawls and extracted content on the user’s machine reduces exposure for internal or staging sites.
  • + Dual interface: CLI fans get powerful scripting options, and less technical users still have an approachable desktop UI with visual status cards and feeds.
  • + SEO-focused out of the box: The built-in 16-check SEO audit saves time versus writing custom rules for common on-page issues.

Cons

  • − No hosted SaaS version: Users must run it locally, which might be less convenient for teams that prefer browser-based tools or cloud scheduling.
  • − Limited native integrations: There is no direct one-click connection to analytics suites, project management tools, or popular SEO platforms.
  • − Niche feature set: It focuses on crawling and on-page checks, so users needing backlink analysis, keyword tracking, or rank monitoring will still need other tools.
