Full-site crawl

Two-phase engine: streaming crawl + post-crawl graph analysis. robots + sitemap aware.

Internal PageRank

LinkScore 1–100, orphan pages, near-duplicate simhash clusters — what cheap tools skip.

Render-diff

Raw vs rendered diff — catches links & content that appear only after JavaScript.

Machine-readable export

One file an LLM actually understands

Every report exports as structured Markdown. Paste into ChatGPT, Claude or Cursor for a prioritized fix plan. Or connect an agent directly over MCP — no HTML scraping, no formatting required.
