Who should pick which

  • Solo developer prototyping AI-generated React components
    Pick: Zcf

    Zcf is free and integrates directly with Claude and Codex, allowing the developer to instantly run JavaScript code without any setup.

  • AI agent builder needing real-time data from the web for RAG
    Pick: Spider Cloud

    Spider Cloud's API and recent Browser AI commands enable agents to crawl and extract structured data at scale, with integrations for LangChain and LlamaIndex.

  • Educator demonstrating AI code execution in class
    Pick: Zcf

    Zcf's zero-config nature and multi-language UI make it easy to show AI-generated code running immediately, with no installation hurdles.

  • Data engineer building a scraper catalog for various websites
    Pick: Spider Cloud

    Spider Cloud's scraper catalog (1,000+ examples) and data connectors provide a head start for building and maintaining scrapers.

  • Hobbyist exploring AI-assisted coding with non-JS languages
    Pick: Spider Cloud

    Zcf is JS-only; Spider Cloud can provide web data for any language via API, but neither is best for non-JS execution. Spider Cloud at least offers data extraction.
