Frequently Asked Questions

Flamehaven Filesearch vs Spider Cloud: which should you choose?

For teams needing private, secure document RAG with no cloud dependency, Flamehaven Filesearch is the clear winner—it’s free, self-hosted, and packed with governance features. If your AI agents need live web data at scale, Spider Cloud’s freemium API with AI extraction and browser automation is the go-to pick. The two tools complement each other rather than compete directly.

Which tool is better for keeping data private?

Flamehaven Filesearch is self-hosted and never sends data to third parties, making it best for privacy. Spider Cloud offers a self-host option but its primary model is cloud-based.

Can I use both tools together?

Yes. Spider Cloud can crawl the web to update a local dataset, which you then index with Flamehaven Filesearch for private RAG queries.

Does Spider Cloud support PDF scraping?

Yes, Spider Cloud’s Rust engine can scrape PDFs and output structured formats like markdown or JSON.

Is Flamehaven Filesearch production-ready?

Yes. It’s built on FastAPI with Docker, includes OWASP security headers, and claims 3-minute deployment for production.

What is the AI Studio in Spider Cloud?

AI Studio is a $6/mo add-on that lets users describe crawling tasks in natural language, and Spider automatically generates the extraction logic.

Does Flamehaven support image search?

Not directly; it focuses on text-based file formats (34 types). For image search, you’d need a separate multimodal model integration.

Which tool has better anti-blocking measures?

Spider Cloud includes stealth anti-detection, rotating proxies, and an unblocker endpoint. Flamehaven does not target web scraping, so it has no such features.

Can I self-host Spider Cloud?

Yes, Spider has an open-source core available on GitHub for self-hosting, but its advanced features (AI extraction, browser commands) may require the cloud API.
