Side-by-side comparison of features, pricing, and ratings

| Deployment | Self-hosted, one-click deploy on Vercel, requires PostgreSQL (e.g., Neon) | Cloud API (SaaS) with optional self-host (open-source core) |
| Target User | Developers building documentation search, self-hosted AI search, LLM.txt generation | AI agents, RAG pipelines, developers needing real-time web data extraction |
| Core Technology | Next.js + LlamaIndex + PgVector / PostgreSQL, OpenAI-powered agent | Rust-based crawler engine, Silk AI model, Browser AI commands (Act, Extract, Observe) |
| Key Features | Vector search, RAG chat widget, LLM.txt generation, scheduled re-indexing, bulk import | Web scraping API, AI Studio, Browser AI commands, captcha solving, data connectors (S3, GCS, etc.) |

If you need a 100% free, self-hosted AI search for your own website (docs/knowledge base) and have dev chops to deploy it, RagRabbit is ideal. But if you need to crawl arbitrary web pages at scale for AI agents or RAG pipelines — with real-time commands, structured output, and data connectors — Spider Cloud's freemium API is the clear winner.
AI web scraping API: crawl, scrape, search any site into markdown or JSON at 10k req/min.
