Million and Spider Cloud serve entirely different needs. If your pain point is ensuring AI-generated code actually works before deployment, Million is the specialized tool—but it's unproven at scale and requires a sales conversation. If you need fast, reliable web data for AI agents or RAG, Spider Cloud is production-ready with a freemium model and clear pricing. Choose based on your primary bottleneck: code correctness vs. data ingestion.

Who should pick which

  • Solo founder building an AI agent
    Pick: Spider Cloud

    Spider Cloud offers a free tier and low-cost pay-as-you-go pricing, plus integrations with LangChain and CrewAI—ideal for prototyping an AI agent that needs web data. Million requires a sales call and is unproven for solo developers.

  • Engineering team using AI coding agents in production
    Pick: Million

    Million specifically targets verification of AI-generated code, which is critical for production-safety. If the team’s bottleneck is trusting AI outputs, Million’s tooling (despite lack of public details) is the only solution focused on this problem.

  • RAG pipeline developer needing fresh web data
    Pick: Spider Cloud

    Spider Cloud’s search endpoint, structured output, and data connectors (S3, GCS, Supabase) directly support RAG pipelines. Its 99.9% uptime and low cost per page make it a practical choice.

  • Enterprise concerned about code security
    Pick: Million

    Million’s verification tools aim to prove AI code is safe and correct, which aligns with enterprise compliance needs. However, the lack of transparent pricing and public case studies may require a proof-of-concept.

  • Hobbyist scraper with simple needs
    Pick: Spider Cloud

    Spider Cloud’s free tier and open-source core allow hobbyists to scrape for free without any commitment. Million has no free option and is overkill for non-agent use cases.
