The honest brief
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
Zep
Stores a temporal knowledge graph (via OSS Graphiti) that versions how facts change over time, not flat snapshots.
- Open-source Graphiti engine (Apache-2.0)
- Managed Zep Cloud option
- Pulls in chat + business data
- Long-term context for agents
- Graph approach has learning curve
- Cloud is credit-based pricing
- Heavier than simple vector memory
- Newer ecosystem
