Frequently Asked Questions

Big AGI vs Spider Cloud: which should you choose?

Choose Big AGI if your core need is cross-validating AI outputs from multiple models with fine-grained control and transparency—it's a power user's Swiss Army knife for LLM evaluation. Choose Spider Cloud if you're building AI agents or RAG pipelines that demand fast, reliable web data extraction at scale—it's purpose-built for crawling and scraping. They solve different problems and can complement each other.

Can Big AGI scrape websites?

Big AGI has a web browsing feature using Google Search API, but it's not a dedicated scraper. For heavy web extraction, Spider Cloud is more appropriate.

Does Spider Cloud support AI model comparison?

No, Spider Cloud is a crawling/scraping API, not an LLM workspace. It provides data for AI agents but doesn't compare models.

Are both tools open-source?

Big AGI is open-source and can be self-hosted with Docker. Spider Cloud's core is also open-source on GitHub, but the cloud service is the primary offering.

Which tool has better integration with LangChain?

Spider Cloud integrates directly with LangChain, LlamaIndex, and CrewAI. Big AGI works with LLM providers, not agent frameworks.

Can I use Big AGI without my own API keys?

No, Big AGI requires you to bring your own API keys from supported providers. The free tier provides the interface, not free model access.

Does Spider Cloud offer a free tier?

Yes, Spider Cloud offers 100 free pages (14-day trial) with no credit card required.

Which tool is better for catching AI hallucinations?

Big AGI, with its Beam feature and AI Inspector, is specifically designed for cross-validating model outputs to detect hallucinations.

Can Spider Cloud extract data from JavaScript-heavy sites?

Yes, Spider Cloud uses a Browser Cloud with stealth anti-detection and can handle JS-heavy pages, plus AI fallback for complex layouts.
