mineru

MinerU parses PDFs, scanned images, Office, OpenDocument, EPUB, OFD, HTML and CSV files into Markdown, HTML, LaTeX, DOCX and structured content lists. It offers four parsing tiers (flash, basic, standard, advanced), a local document library with search, and page/block locators for citations. It ships a CLI, Python SDK, API, router and Gradio WebUI, plus an agent skill.

Who it is for: Engineers feeding PDFs and Office documents to LLM pipelines or agents

Strengths

  • Handles scanned PDFs, tables and formulas, with four quality tiers from fast preview to advanced
  • Stable doc/tier/page/block locators allow paged reading and citation of long documents
  • Small models run on ONNX CPU; the VLM can run on llama.cpp, vLLM or LMDeploy
  • Documents are not uploaded to the official service unless remote parsing is configured

Weaknesses

  • Office, HTML, EPUB, OFD and CSV files only get flash-tier parsing; higher tiers are PDF and image only
  • Docker deployment for non-NVIDIA devices is pending an update
  • Highest throughput needs an NVIDIA GPU and mineru[full]; Windows needs torch installed separately
  • License is reported as NOASSERTION, so terms need checking before use
  • GPU optional
  • Docker + Compose
  • Needs Python >=3.10,<3.15, llama.cpp, vLLM or LMDeploy (VLM runtime), ONNX or Torch
  • Models: MinerU VLM, ONNX small models, Torch small models, llama.cpp, vLLM

Crawl4AI

Crawl4AI is a Python library, CLI (`crwl`) and Docker REST server that drives Playwright browsers (Chromium, Firefox, WebKit) to turn web pages into clean or filtered Markdown. It extracts structured data with CSS/XPath/regex schemas without an LLM, or through any LiteLLM-supported provider into a typed JSON schema. It also supports deep crawls, adaptive crawling and batch fetching. A hosted Crawl4AI Cloud with search and answer endpoints is sold separately.

Who it is for: Developers feeding web content into RAG, agents and data pipelines

Strengths

  • Schema-based CSS/XPath extraction runs without any LLM call
  • Fit Markdown filters (pruning, BM25, LLM) strip menus and boilerplate
  • Persistent profiles, CDP remote browsers, rotating proxies and stealth mode
  • Docker server exposes /md, /crawl, /screenshot, /pdf, plus MCP, dashboard and playground

Weaknesses

  • Search, SERP and answer endpoints exist only in the paid hosted cloud
  • Bot-wall handling when self-hosted depends on your own proxies and settings
  • Needs a Playwright browser install via crawl4ai-setup
  • README asks for attribution when you use it
  • no GPU
  • Docker + Compose
  • Needs Playwright browsers (Chromium), Docker (optional), LLM provider API key (optional)
  • Models: LiteLLM providers, OpenAI, Ollama
  • port 11235
