The honest brief
mem0
Fastest path to agent memory — extracts distilled facts with a tiny token footprint and the biggest community.
- Quick to adopt, broad framework integrations
- Stores distilled facts, small footprint
- Vector + graph + key-value storage
- Open-source with usable free tier
- Weaker on temporal/state-change queries
- LLM call on every write adds latency
- Test deletion/conflict handling for regulated use
- More library than full memory server
Memvid
No database or infra to run — memory ships as one portable, offline .mv2 file with sub-5ms retrieval, unlike server-based memory layers.
- No vector DB or RAG pipeline to run
- Works fully offline
- Model-agnostic and multimodal
- Apache-2.0 licensed
- Append-only, versioned storage
- Video-frame approach is novel and debated
- Smaller ecosystem than mem0-style stacks
- Young commercial offering (2026)
- Best for embed/edge, not multi-writer servers
