The honest brief

Crawl4AI

Self-host-first crawler whose core needs no API key, among GitHub's most-starred web-to-Markdown tools.

  • Core runs fully locally
  • Handles JS rendering
  • Clean LLM-ready Markdown
  • Python library, CLI, or Docker server
  • You run the infra
  • Hosted Cloud API still beta
  • Optional LLM extraction adds cost

Docling

Self-hostable with AI layout detection that preserves reading order and table structure — no API bills.

  • Runs on a laptop via Python API or CLI
  • OCR for scans, hybrid chunker built in
  • IBM Research origin, now LF AI project
  • Wide input format and export support
  • Lower accuracy than top hosted parsers
  • No managed cloud / SLA out of the box
  • Setup and tuning effort vs. an API
  • Heavier compute for OCR-heavy docs
