## What the models said for it

- "MongoDB - If you need flexible schemas, strong query capabilities, and a mature ecosystem. Good for B2B apps with complex data relationships." (Claude Haiku 4.5, NoSQL)
- "The Best All-Rounder: MongoDB (via MongoDB Atlas) ... widely considered the safest, most flexible default choice for mid-market businesses." (Gemini 3.5 Flash, NoSQL)
- "For most small businesses, MongoDB and Redis are the easiest to start with due to their free tiers and strong community support." (Mistral Small, NoSQL)
- "For documents: Start with MongoDB Atlas. It's the most widely adopted, well-documented, and supported choice for B2B workloads" (GLM 4.7 FlashX, NoSQL)

## And against it

- "Risk Level: High
MongoDB has been the target of massive automated botnets in the past due to its default insecure settings." (GLM 4.7 FlashX, NoSQL)
- "Frequent production stories of slow queries, memory leaks, long restarts at scale (e.g., 4TB+ clusters), shard key hotspots. Security exploits in older versions." (Grok 4.1 Fast, NoSQL)
- "MongoDB (Be Cautious): ... the SSPL requires you to open-source your entire backend infrastructure" (Gemini 3.5 Flash, NoSQL)
- "Storage Bloat: MongoDB stores field names with every document ... It is known to be "heavy."" (Qwen 3.7 Flash, NoSQL)
