Crawl4AI is an open-source (Apache 2.0) web crawler and scraper built for AI pipelines, converting pages into clean Markdown or structured data for RAG, agents, and data pipelines. The core runs locally with no API key, handles JS rendering, and supports optional LLM-based extraction with any provider. It installs as a Python library/CLI or deploys as a Dockerized FastAPI server; a hosted Cloud API is in closed beta.

    Turn any website into clean, LLM-ready data — scrape, crawl, search.

    A web data API for AI — scrape, crawl, map, and search pages into clean markdown or structured JSON, handling proxies, anti-bot, and JS rendering for you. Open-source core (AGPL) plus a hosted service; a default web-ingestion layer for agents and RAG pipelines.

    ScrapeGraphAI

    Turn any webpage into structured data with one prompt-driven API call.

    ScrapeGraphAI is an AI web-scraping tool that extracts structured data from pages and documents using natural-language prompts instead of CSS selectors or XPath, orchestrating LLMs in graph-style pipelines (single-page, multi-page, search, crawl). The core library is open-source under the MIT license with Python and Node SDKs; a hosted API adds a credit-based free tier and paid plans, plus integrations with LangChain, LlamaIndex, n8n, and an MCP server.

    Apify

    Full-stack web scraping and browser automation platform for AI data.

    A cloud platform for web scraping, data extraction, and browser automation built around 'Actors' — serverless programs that crawl sites and return structured data. Its store offers tens of thousands of ready-made Actors, and outputs clean Markdown or JSON that feed LLMs, vector databases, and RAG pipelines via LangChain and LlamaIndex. The company also maintains the open-source Crawlee crawling library for local development.

    Docling Project

    Toolkit that turns documents into AI-ready Markdown and JSON.

    A document-processing toolkit that converts PDF, DOCX, PPTX, XLSX, HTML, images, and audio into clean Markdown or JSON for LLM and RAG pipelines. It does advanced PDF understanding — page layout, reading order, table structure, and OCR for scans — and ships a hybrid chunker plus native LangChain and LlamaIndex integrations. Small enough to run on a laptop via a Python API or CLI; MIT-licensed and community-governed.
