Diffbot reads the public web like a person and turns it into structured data: an Extract API for articles and products, a Crawl service, a Natural Language API, and a Knowledge Graph of billions of entities and over a trillion facts. The graph is refreshed continuously, so AI systems can ground answers in current, verifiable data rather than model memory. Diffbot also ships its own factually grounded GraphRAG language model.

Pros & cons

  • Trillion-fact, continuously refreshed graph
  • Open-source GraphRAG LLM released
  • Extract, Crawl, and NL APIs over the open web
  • Free tier, no credit card required
  • Strong factual-grounding benchmarks
  • Enterprise pricing for serious volume
  • Niche versus general LLM tooling
  • Graph coverage varies by entity type

    Firecrawl

    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.

    Worth knowing

    Built by Italian founders Marco Vinciguerra and Lorenzo Padoan; the open-source library has passed 20,000 GitHub stars.

    Crawl4AI

    Open-source crawler that turns the web into clean, LLM-ready Markdown.

    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.
