Mengram and Spider Cloud serve fundamentally different needs: one provides persistent memory for AI agents, the other live web data. If your priority is giving agents long-term recall across sessions, start with Mengram's free tier and scale up. If you need real-time web scraping with structured output for RAG, Spider Cloud is the clear choice thanks to its cheap per-page cost and extensive catalog. For most teams, you'll likely need both eventually.
