utopia vs graphrag
Self-hosted graph-based knowledge and AI search compared
utopia and graphrag both turn documents into graph-backed knowledge that can support natural-language questions. utopia emphasizes time-aware facts, evidence, and human review, while graphrag focuses on retrieval and chat built around TigerGraph.
utopia: Build a Time-Aware Enterprise Knowledge System
Utopia is a self-hosted knowledge system that turns documents and observations into an ontology-guided, bitemporal graph. It combines search, evidence-backed answers, agent access, and human review for teams that need to track how knowledge and decisions change.
graphrag: Build Graph-Powered AI Search and Chat
TigerGraph GraphRAG builds a knowledge graph from documents and combines graph queries with vector retrieval to answer natural-language questions. It suits teams already using TigerGraph that want a self-hosted, configurable RAG application.

Key differences
- utopia is a bitemporal knowledge system that tracks when facts were valid and when they were learned; graphrag builds document graphs for retrieval and question answering.
- utopia combines Tantivy and pgvector search with cited answers and an editable ontology; graphrag combines TigerGraph vector search and graph traversal, with Classic and Agentic chat modes.
- utopia is written in Rust and uses PostgreSQL with pgvector; graphrag is written in Python and supports TigerGraph as its only graph and vector database.
- utopia uses the Apache-2.0 license; graphrag uses AGPL-3.0.
- utopia is at v0.1 and advises pinning versions because its schema evolves; graphrag is provided as-is, with official support limited to work delivered through a Statement of Work.
- utopia includes a human review queue and read-only MCP tools for governed agent access; graphrag offers a web chat interface, admin UI, APIs, and external MCP tools in its agentic engine.
Choose utopia if you…
- need to reconstruct what was known or true at a past date, with source evidence.
- want ontology-guided extraction, conflict review, and governed agent access.
- can operate PostgreSQL with pgvector and configure chat and embedding model endpoints.
Choose graphrag if you…
- already use TigerGraph and want document-based graph retrieval or questions about existing graph data.
- want to compare planned and reactive agentic chat approaches or connect external MCP tools.
- can operate TigerGraph and configure an LLM provider, while reviewing the AGPL-3.0 license for your deployment.
