// how it works
How it works
- Start the prebuilt image
Clone the repo and bring the stack up with Docker Compose — the first account you register becomes the administrator.
- Configure model endpoints
Under Administration → Models, set the chat and embedding endpoints Utopia should use.
- Feed it knowledge
Start extracting business documents into the public knowledge base and watch the ontology evolve with time awareness.
// features
Why people love it
Bitemporal by design
Knowledge carries both valid time and record time, so past states of understanding can be replayed and audited.
Ontology in the base layer
Conflict detection, reasoning and decision support run against a governed ontology, not raw chunks.
Offline and self-hosted
Prebuilt images for x86-64 and ARM64 (Apple Silicon, Graviton) run entirely on hardware you control.
An execution gate is coming
The roadmap adds checking agent calls against ontology rules and symbolic logic, plus agent memory over MCP.

// run it
Run it yourself
- Clone the repository
Requirements: Docker; local development also needs Rust 1.85+, Node 20+ and pnpm.
git clone https://github.com/deeplethe/utopia.git cd utopia - Start from the prebuilt image
Brings up the app profile; then open http://localhost:1516 and register.
docker compose --profile app up -d - Or build from source
Uses the build overlay of the same Compose stack.
docker compose -f docker-compose.yml -f docker-compose.build.yml --profile app up -d --build
// use cases
What you can build
- Building a company knowledge base whose answers can be audited later
- Tracking how understanding of a contract, regulation or codebase changed over time
- Giving agents a governed memory with conflict detection instead of a plain vector store
- Offline knowledge infrastructure for regulated environments

// faq
Questions, answered
Who maintains Utopia?
DeepLethe; the project site is utopia.bi.
Is it free?
Yes, Apache-2.0 licensed, with prebuilt container images on GHCR.
Does it need a paid API key?
You configure your own chat and embedding model endpoints; Utopia itself has no licence fee.
How does it compare to a well-known alternative?
A vector store retrieves similar chunks of present knowledge. Utopia models knowledge bitemporally over an ontology, so it can show what was believed, when it changed, and what a decision rested on.
How do I get started?
Clone the repo, run docker compose --profile app up -d, open http://localhost:1516, register the admin account, and configure your model endpoints.
