ZeroDB
Memory, vectors, events, and files — one API for AI agents that remember. The Mem0 alternative built for production agents.
npx zerodb-cli initThe Full Knowledge Layer for AI Agents
Everything your agents need to remember, reason, and act — memory, vectors, events, files, and knowledge graphs in one API.
ZeroMemory — Cognitive Agent Memory
Working memory, episodic recall, and semantic memory layers with automatic consolidation, decay scoring, and entity relationship graphs.
Vector Search with pgvector HNSW
Sub-millisecond semantic search backed by pgvector HNSW indexes. Free embeddings included — no OpenAI key required.
NoSQL Tables + Event Streams
Schema-free document tables and real-time event streaming alongside vector storage — one API for your full agent data layer.
File Storage (S3-Compatible)
Agent-native object storage for documents, images, and artifacts. Multi-tenant scoping with fine-grained access controls.
MCP Server Integration
10-tool memory MCP server and 83-tool full database server. Works with Cursor, VS Code, and AINative Studio IDE. Hosted remote MCP available — no local install needed.
Context Graph + GraphRAG
Multi-hop knowledge graph traversal with GraphRAG hybrid search. Ontology-aware entity resolution, edge versioning with contradiction detection, and 5 pre-built semantic templates.
