Frequently Asked Questions

ClickHouse vs Spider Cloud: which should you choose?

Choose ClickHouse if you need a blazing-fast, petabyte-scale analytics database for real-time dashboards or observability; choose Spider Cloud if you need to reliably scrape the web and feed structured data into AI agents or RAG pipelines.

No. ClickHouse has no built-in web crawling. You would use Spider Cloud (or another scraper) to feed data into ClickHouse for analysis.

Which tool is better for AI agents?

Spider Cloud directly serves AI agents with Browser AI commands and structured output. ClickHouse can be used as a vector store for agent memory, but it's not a data source.
