utopia is a self-hosted, Rust-based RAG system built on PostgreSQL with pgvector, described by its author as an open-source enterprise world model. Its topics indicate bitemporal, temporal knowledge-graph storage with ontology, semantic search, and GraphRAG capabilities.

Reach for it when you want a self-hosted, graph- and time-aware knowledge base for LLM retrieval instead of plain vector search.

Use it to

  • Self-host a temporal knowledge graph on PostgreSQL
  • Build agent memory with bitemporal tracking
  • Run GraphRAG over an enterprise ontology
  • Add semantic search to LLM applications
