RLama’s Tech Stack and Architecture
RLama’s robust design is built on a modern tech stack, ensuring performance and scalability.
Tech Stack
- Core Language: Go – Chosen for its speed, cross-platform compatibility, and single-binary distribution.
- CLI Framework: Cobra – Provides a structured, user-friendly command-line interface.
- LLM Integration: Ollama API – Powers embeddings and completions for AI-driven responses.
- Storage: Local filesystem (JSON) – Simple, portable, and dependency-free.
- Vector Search: Custom cosine similarity – Enables efficient embedding retrieval.
Architecture
RLama follows a clean architecture pattern, separating concerns for maintainability:
rlama/
├── cmd/ # CLI commands
│ ├── root.go # Base command
│ ├── rag.go # Create RAG systems
│ ├── run.go # Query RAG systems
├── internal/
│ ├── client/ # Ollama API integration
│ ├── domain/ # Core models (RAG, documents)
│ ├── repository/ # Data persistence
│ └── service/ # Business logic
└── pkg/ # Shared utilities
└── vector/ # Vector operations
This modular structure ensures RLama remains lightweight while delivering powerful functionality.
Data Flow
RLama processes documents in five key steps:
- Document Processing: Loads and parses files into plain text.
- Embedding Generation: Sends text to Ollama for vector embeddings.
- Storage: Saves the RAG system (documents + embeddings) in
~/.rlama. - Query Process: Converts user questions into embeddings and retrieves relevant content.
- Response Generation: Uses Ollama to generate answers based on retrieved data.

Using RLama: Key Commands
RLama’s CLI offers a range of commands to create, manage, and query RAG systems. Here’s how to use them effectively.
1. Create a RAG System (rag)
To index your documents and create a RAG system:
rlama rag [model] [rag-name] [folder-path]
- model: Ollama model (e.g.,
llama3,mistral). - rag-name: Unique name for your RAG system.
- folder-path: Directory containing your documents.
Example:
rlama rag llama3 documentation ./docs
This command indexes all documents in the ./docs folder under the documentation RAG system.
2. Query a RAG System (run)
Start an interactive session to ask questions:
rlama run [rag-name]
Example:
rlama run documentation
> How do I install the project?
> What are the main features?
> exit
RLama retrieves relevant content and generates answers in real-time.
3. List RAG Systems (list)
View all available RAG systems:
rlama list
4. Delete a RAG System (delete)
Remove a RAG system and its data:
rlama delete [rag-name] [--force/-f]
Example:
rlama delete old-project --force
The --force flag skips confirmation.
5. Update RLama (update)
Keep RLama up-to-date:
rlama update [--force/-f]
6. Check Version (version)
Display the current RLama version:
rlama --version
Global Flags
Customize Ollama connections with:
--host: Ollama host (default:localhost).--port: Ollama port (default:11434).
Example:
rlama --host 192.168.1.100 --port 8080 run my-rag
Supported Document Formats
RLama supports a wide range of file types, making it versatile for various use cases:
