Crawlith is a modular, production-grade SEO crawl intelligence platform built for serious technical SEO analysis.
It is not another surface-level site scanner.
It is a structured crawl engine designed to extract graph intelligence, structural weaknesses, content risks, and authority signals from any website — at scale.
Crawlith is a multi-package architecture composed of:
- Core Engine – High-performance crawler and scoring system
- CLI Interface – Power-user command-line control
- Server Layer – Lightweight API for automation and integrations
- Web UI – Clean, modern interface for visual analysis
It is designed to scale from:
- Single-site audits
to - Multi-site crawl intelligence environments.
Crawlith focuses on:
- Structural crawl accuracy (BFS-based site graph)
- Deterministic URL normalization
- Scalable multi-site support
- Snapshot-based comparisons
- Clean, analyzable JSON / SQLite outputs
- Modular extensibility (future plugin-ready)
No bloat. No vague “AI magic.”
Just measurable crawl intelligence.

- Page limits
- Redirect handling
- MIME filtering
