NeuronDB

AI-Native PostgreSQL Extension for Vector Search, Agents, and Transactional Memory.

NeuronDB is an open-source PostgreSQL extension designed for building AI-native systems directly inside the database.

It combines:

• Vector similarity search
• Agent execution
• Transactional memory
• Retrieval-Augmented Generation (RAG) support
• Deterministic SQL-based AI workflows

What NeuronDB Provides

Native Vector Search

High-performance embedding storage and similarity search inside PostgreSQL.

Transactional RAG Memory

Version-aware memory with MVCC guarantees. Consistent reads. No partial state retrieval. No memory drift under concurrency.

Agent Integration

Seamless integration with:

• NeuronAgent
• NeuronMCP
• neuron-cloud (optional control plane)

Deterministic AI Pipelines

SQL-driven reasoning workflows. Auditable execution. Reproducible outputs.

Ecosystem
