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
