Why teams choose ZeroDB over Mem0
Full database, not just a memory wrapper
Mem0 layers memory on top of your existing database. ZeroDB is the database — vectors, NoSQL documents, relational tables, files, and event streams all in one product. One API, one bill, no glue code.
MCP integration built-in
ZeroDB ships with two MCP servers: a 6-tool memory server and a 69-tool full database server. Wire it directly into Claude, Cursor, or any MCP-compatible host with a single config line. No extra infrastructure required.
Knowledge graph with entity relationships
ZeroMemory automatically extracts entities and builds a relationship graph as your agent operates. Query connections between concepts, people, and events — not just raw text similarity.
Self-host or cloud — your choice
Run ZeroDB on your own infrastructure for full data sovereignty, or use the managed cloud. Mem0 is cloud-only. ZeroDB gives you the flexibility enterprises and privacy-conscious teams need.
Give your agents real memory infrastructure
Zero setup. Free embeddings included. One command to start.
