## Warned against

- MongoDB: 17 of 75 labels negative. "MongoDB switched to the SSPL in 2018. This creates legal ambiguity ... making the free community version increasingly insufficient for production." (Qwen 3.7 Flash, negative prompt)
- Redis: 14 of 41 labels negative. "Redis changed its license from open-source BSD to SSPL in March 2024, making it no longer truly open-source... Consider Valkey instead" (Claude Haiku 4.5, negative prompt)
- Apache Cassandra: 10 of 43 labels negative. "Complex to operate, and Cassandra's eventual consistency + CQL query limitations make it a poor fit for transactional B2B applications." (DeepSeek V4 Flash, direct prompt)
- Apache CouchDB: 5 of 8 labels negative. "slow for writes at scale, has limited querying ... Rarely chosen for new enterprise projects." (Grok 4.20, negative prompt)
