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

- 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
