Who should pick which

  • AI Agent Developer
    Pick: Spider Cloud

    Spider Cloud provides real-time web data extraction via API, including new Browser AI commands for interactive scraping. LMCache does not fetch external data.

  • LLM Inference Engineer
    Pick: LMCache

    LMCache reduces latency and cost by caching KV caches, integrating directly with vLLM/TGI. Spider Cloud offers no inference acceleration.

  • RAG Pipeline Builder
    Pick: Spider Cloud

    Spider Cloud crawls and structures documents for RAG ingestion; LMCache can later speed up inference on that data, but the primary data acquisition need is Spider Cloud.

  • Cost-conscious Startup
    Pick: LMCache

    LMCache is free and open-source, potentially cutting LLM serving bills by 8x. Spider Cloud's per-page cost is low but still a variable expense.

  • Enterprise with High Volume Scraping
    Pick: Spider Cloud

    Spider Cloud's Rust engine and data connectors (S3, GCS) support bulk, reliable scraping at $0.03/1k pages. LMCache handles a different problem.
