Where Mem0 wins
- Preserves historical factsBecause Supermemory overwrites changed facts and deletes expired ones, prior states are lost. Mem0 keeps dated facts for history queries.
- Uncapped self-hostingSupermemory caps its free local binary at 10,000 docs (production self-hosting starts at $399/mo). Mem0 has no document cap.
- Simpler pricing with your own keySupermemory meters ingestion tokens, queries and rerank ops separately. Mem0 gives 50,000 adds/mo free when you bring an LLM key.
