AltiusOne Community & Desktop — Open Source Without Compromise

The power of AltiusOne, at your place

AltiusOne is available in two open source editions: Community (self-hosted with Docker) and Desktop (native Electron application). Both offer the same 15 modules as the Cloud edition.

Community Edition — Docker Compose

Install AltiusOne on your own server in a few commands:

git clone https://github.com/altiusone/altiusone.git
cd altiusone
cp .env.example .env
# Edit .env with your settings
docker compose up -d

That's it. You get the full stack:

• Django + Gunicorn
• PostgreSQL + PostGIS + pgvector
• Redis + Celery
• MinIO
• Nextcloud + OnlyOffice
• Nginx

System requirements

Desktop — Native application

The Desktop edition is an Electron application available for:

• Windows 10/11 (x64)
• macOS 12+ (Intel & Apple Silicon)
• Linux (AppImage, .deb)

Desktop features

• Full offline mode — work without an internet connection
• Automatic synchronisation — your data syncs as soon as the connection is restored
• Local database — SQLite for offline mode, sync with PostgreSQL online
• Automatic updates — notifications and one-click installation
• CI/CD GitHub Actions — automatic builds for all 3 platforms

Bring Your Own AI

The Community and Desktop editions support flexible AI integration:

MCP Server (Model Context Protocol)

AltiusOne exposes an MCP server at the /mcp/ endpoint (JSON-RPC + SSE) that allows any compatible client (Claude Desktop, VS Code, etc.) to interact with your data:

• Browse accounting entries
• Search for clients and suppliers
• Analyse the relationship graph
• Generate reports

OpenAI-compatible API

Connect your own language model:

• Ollama — local models (Llama, Mistral, etc.)
• vLLM — high-performance GPU inference
• Any OpenAI-compatible provider — simply configure the URL and API key

# settings.py
AI_BACKEND = "openai_compatible"
AI_BASE_URL = "http://localhost:11434/v1"  # Ollama
AI_API_KEY = "ollama"
AI_MODEL = "llama3.1:8b"
