Website Content Crawler

Website Content Crawler is Apify’s flagship web data collection tool for AI training data. It deep-crawls docs, strips headers/footers, solves CAPTCHAs, and exports Markdown, plain text, or HTML. Built-in connectors for LangChain, Hugging Face, LlamaIndex, and Pinecone let you stream the output straight into a vector database or RAG pipeline.

Firecrawl

Firecrawl focuses on one thing: turning any URL (and every internal link it finds) into clean Markdown through a simple REST API. It executes client-side JavaScript, deduplicates boilerplate, and ships language-model-ready text in minutes—ideal when you only need the raw content and prefer a self-hosted solution.

LLM Scraper

LLM Scraper is a TypeScript library that uses function-calling to map the DOM into a JSON schema you define, giving you structured data instead of free-form text. Version 1.6 adds Vercel AI SDK 4 support, stronger type safety, and code generation helpers.

GPT-Crawler

GPT-Crawler crawls documentation sites with a headless browser and automatically produces “knowledge files” you can upload to OpenAI Assistants or custom GPTs. It’s perfect when you want a single JSON file that ChatGPT can ingest without extra tooling.

ScrapeGraphAI

ScrapeGraphAI builds an LLM-directed graph of extraction steps (scroll, click, paginate) and then executes it asynchronously. The result is clean JSON or CSV produced by a Python API that can adapt to complex, multi-step sites where static crawlers struggle.

Skyvern

Skyvern automates browsers with computer vision. Instead of relying on DOM selectors, its agents “see” the page, click buttons, fill forms, and download files—surviving redesigns that break traditional crawlers. It offers an API for massive parallel runs and built-in CAPTCHA solving.

RAG Web Browser

RAG Web Browser takes a search-first approach: it queries Google, grabs the top-K links, and processes each one through Website Content Crawler, returning neatly chunked Markdown ready for retrieval-augmented generation workflows.
