Spider Cloud is ideal if your priority is high-performance web data extraction (crawling, scraping, search) for AI agents and RAG pipelines, with a scalable pay-as-you-go cloud API. Restai is better if you need a full self-hosted AI platform with RAG, agents, visual builder, and enterprise features like RBAC and white-labeling, but you must manage your own infrastructure. Choose based on whether you need data retrieval or a comprehensive AI back-end.

Frequently Asked Questions

Restai vs Spider Cloud: which should you choose?

Spider Cloud is ideal if your priority is high-performance web data extraction (crawling, scraping, search) for AI agents and RAG pipelines, with a scalable pay-as-you-go cloud API. Restai is better if you need a full self-hosted AI platform with RAG, agents, visual builder, and enterprise features like RBAC and white-labeling, but you must manage your own infrastructure. Choose based on whether you need data retrieval or a comprehensive AI back-end.

Which tool is better for web scraping?

Spider Cloud is purpose-built for web scraping with a Rust engine, AI extraction, and a scraper catalog. Restai does not offer direct scraping; its agents can fetch web data indirectly but not as efficiently.

Can Restai scrape websites like Spider Cloud?

No, Restai does not have a built-in scraping API. It can use agents to call external APIs, but it is not optimized for raw web data extraction.

Which is more cost-effective at scale?

Spider Cloud charges $0.03 per 1,000 pages, which is very cheap for high volume. Restai is free software but you pay for hosting and LLM API costs; if you already have servers, Restai may be cheaper overall.

Does Restai have a cloud version?

No, Restai is self-hosted only. Spider Cloud offers a managed cloud API.

Can I use Spider Cloud for non-web data tasks?

Spider Cloud is specialized for web data. It is not designed for general AI tasks like building custom chatbots or managing LLM projects.

Does Restai support multi-user and access control?

Yes, Restai includes RBAC, OAuth/LDAP/OIDC, TOTP 2FA, and audit logging, making it suitable for enterprise teams.

Which tool has better LLM integration?

Restai integrates with 11+ LLM providers (Ollama, vLLM, OpenAI, etc.) and supports vector stores. Spider Cloud focuses on data extraction; LLM integration is via LangChain/LlamaIndex connectors.

What are the latest updates for each tool?

Spider Cloud recently added Browser AI commands (Act/Extract/Observe) and a scraper catalog. Restai has no recent news; it's a stable open-source release.
