OpenTier turns organizational knowledge into real-time, actionable intelligence. It's secure by design, fast by default, and built to scale with your business.
SYSTEM OUTPUT · SIMULATION MODE
OpenTier combines the performance of Rust with the intelligence of Python,
creating a production-ready platform that scales with your needs.
Rust handles authentication, rate limiting, streaming, and all public-facing APIs with blazing-fast performance and memory safety.
Strongly-typed contracts ensure clean separation and enable independent evolution of both layers without breaking changes.
Python powers all intelligence: RAG, embeddings, chat orchestration, and ML inference, isolated from public traffic.
Lightning-fast API gateway built with Rust for maximum performance, security, and reliability.
Advanced retrieval-augmented generation with pgvector for semantic search and context-aware responses.
Server-sent events and gRPC streaming for instant, responsive chat experiences.
OAuth 2.0, session management, rate limiting, and role-based access control built-in.
Clean separation between control (Rust) and cognition (Python) for predictable scaling.
PostgreSQL with pgvector extension for efficient embedding storage and similarity search.
Automated data pipelines for cleaning, normalizing, and embedding your knowledge base.
Built-in observability, metrics, tracing, and backpressure handling for reliable operations.
Rust gateway, Python intelligence engine, and Postgres —> runs locally via Docker Compose.
Clone & Configure
Grab the repo and configure your environment — DB credentials, LLM API keys, and OAuth secrets.
git clone https://github.com/Celestial-0/OpenTier cd OpenTier/server cp .env.example .env
Run the Stack
One command spins up PostgreSQL, runs migrations, then starts the Rust gateway and Python intelligence engine.
docker compose up # PostgreSQL + pgvec → :5432 # Migrations → auto # Python intelligence → :50051 # Rust API gateway → :4000
Query the API
Hit the local Rust gateway directly from any HTTP client once the stack is live.
curl http://localhost:4000/v1/chat \
