Frequently Asked Questions
Cavemem vs Spider Cloud: which should you choose?
Choose Spider Cloud if your AI agent needs live web data for RAG or scraping — its Rust-powered engine and 1,000+ ready-made scrapers make data ingestion cheap and fast. Choose Cavemem if you build coding agents and want to slash token costs by retaining context locally via MCP. They solve different problems: one pulls external data, the other remembers internal conversation history.
Can Spider Cloud and Cavemem be used together?
They could complement each other: Spider Cloud scrapes web data for an agent's knowledge base, while Cavemem stores the agent's own memories. They are built for different layers of an agent stack.
Which tool is better for reducing token usage in coding agents?
Cavemem is designed specifically for this: it persists context locally and recalls compressed memories via MCP, reducing the need to re-send full history. Its new Ctx feature loads only relevant tools.
Does Spider Cloud require credit card for free tier?
Spider Cloud's free tier includes 500 credits without requiring a credit card by default, based on typical SaaS freemium practices (check current policy).
Is Cavemem limited to Caveman ecosystem only?
No, Cavemem is MCP-compatible and works with 30+ agents and any MCP client, including Claude Code, OpenAI API, and Gemini.
Does Spider Cloud support real-time streaming?
Spider Cloud offers Browser AI commands via WebSocket for real-time interaction (Act, Extract, Observe), plus standard REST API responses.
Can Cavemem sync across multiple machines?
Cavemem is local-first; cloud sync is on waitlist with Caveman Cloud. For multi-machine sync today, manual database sharing is needed.
What is the success rate of Spider Cloud?
Spider Cloud advertises a 99.9% success rate, with failed requests not billed.
What is the main benefit of Cavemem's compression?
Content-addressed compression stores memories efficiently, reducing disk space and token usage when recalling context via MCP.
