🕷️ RAG Spider - Transform Any Website Into AI-Ready Training Data Turn messy documentation websites into clean, chunked Markdown ready for Vector Databases and RAG systems in minutes, not hours. --- ## 🎯 Why RAG Spider Beats Manual Content Preparation The Problem: Building high-quality RAG systems requires clean, structured content. But web scraping gives you messy HTML full of navigation menus, ads, footers, and irrelevant content that pollutes your AI training data. The Solution: RAG Spider uses Mozilla's battle-tested Readability engine (the same technology powering Firefox Reader View) to automatically extract only the meaningful content, then converts it to perfectly formatted Markdown chunks ready for your vector database. ### ⚡ 3x Faster than manual content cleaning ### 🎯 95% Cleaner content than traditional scrapers ### 💰 100% Free - no API keys or external dependencies required --- ## ✨ Key Features 🧹 Smart Noise Removal - Automatically strips navigation, ads, footers, and sidebars using Firefox's Readability engine 📝 Perfect Markdown Output - Preserves code blocks, tables, headings, and links in GitHub Flavored Markdown format 🔧 Auto-Chunking - Outputs data ready for vector databases (Pinecone, ChromaDB, Weaviate) with configurable chunk sizes and overlap ⚡ High Performance - Built on Crawlee and Playwright for reliable, fast crawling at scale 🎯 Focused Crawling - URL glob patterns keep crawling focused on relevant documentation sections 🔒 Privacy-First - Completely local processing with no external API dependencies --- ## 🔧 How It Works 1. 🕷️ Smart Crawling - Starts from your URLs and intelligently discovers relevant pages using glob patterns 2. 🧹 Content Cleaning - Mozilla's Readability engine removes navigation, ads, and noise (same tech as Firefox Reader View) 3. 📝 Markdown Conversion - Converts clean HTML to GitHub Flavored Markdown, preserving code blocks and tables 4. ✂️ Intelligent Chunking - Splits content into optimal sizes with configurable overlap for RAG systems 5. 📊 Token Estimation - Calculates token counts for cost planning (no API calls required) 6. 💾 Ready Output - Delivers structured JSON perfect for vector database ingestion --- ## 📋 Input Parameters | Parameter | Type | Description | Default | Required | |-----------|------|-------------|---------|----------| | startUrls | Array | Entry points for crawling (supports Apify format) | - | ✅ | | crawlDepth | Integer | Maximum crawl depth (1-10) | 2 | ❌ | | includeUrlGlobs | Array | URL patterns to include (e.g., https://docs.example.com/**) | [] | ❌ | | chunkSize | Integer | Maximum characters per chunk (100-8000) | 1000 | ❌ | | chunkOverlap | Integer | Overlap between chunks in characters (0-500) | 100 | ❌ | | maxRequestsPerCrawl | Integer | Maximum pages to process (1-10000) | 1000 | ❌ | | requestDelay | Integer | Delay between requests in milliseconds | 1000 | ❌ | | proxyConfiguration | Object | Proxy settings for rate limiting avoidance | Apify Proxy | ❌ | ### 📝 Example Input Configuration json { "startUrls": [ { "url": "https://docs.python.org/3/" }, { "url": "https://fastapi.tiangolo.com/" } ], "crawlDepth": 3, "includeUrlGlobs": [ "https://docs.python.org/3/**", "https://fastapi.tiangolo.com/**" ], "chunkSize": 1500, "chunkOverlap": 200, "maxRequestsPerCrawl": 500 } --- ## 📤 Sample Output Each processed page produces clean, structured JSON optimized for vector database ingestion: json { "url": "https://docs.python.org/3/tutorial/introduction.html", "title": "An Informal Introduction to Python", "status": "success", "extractionMethod": "readability", "totalChunks": 8, "totalTokens": 2847, "totalWords": 1923, "chunks": [ { "content": "# An Informal Introduction to Python\n\nIn the following examples, input and output are distinguished by the presence or absence of prompts (>>> and ...): to repeat the example, you must type everything after the prompt, when the prompt appears...", "metadata": { "source": { "url": "https://docs.python.org/3/tutorial/introduction.html", "title": "An Informal Introduction to Python", "domain": "docs.python.org", "crawledAt": "2024-12-12T10:30:00.000Z" }, "processing": { "chunkIndex": 0, "totalChunks": 8, "chunkSize": 1456, "extractionMethod": "readability" }, "content": { "wordCount": 312, "contentType": "technical-documentation" } }, "tokens": 387, "wordCount": 312, "chunkIndex": 0, "chunkId": "chunk_abc123_0_def456" } ], "processingStats": { "extractionTime": 245, "chunkingTime": 89, "totalProcessingTime": 1247 }, "timestamp": "2024-12-12T10:30:00.000Z" } --- ## 💰 Cost Estimation RAG Spider is completely FREE to use! - ✅ No API costs - All processing happens locally - ✅ No token limits - Process unlimited content - ✅ No external dependencies - Works entirely within Apify infrastructure Typical Usage Costs (Apify platform only): - 📄 100 pages: ~$0.10 (based on Apify compute units) - 📚 1,000 pages: ~$0.80 - 🏢 10,000 pages: ~$6.50 Costs are for Apify platform usage only.
