Installation

Prerequisites

• Docker — Install Docker
• uv — curl -LsSf https://astral.sh/uv/install.sh | sh
• Node.js & npm — Install Node.js (or use nvm)

Quick Start

# 1. Clone the repository
git clone https://github.com/Intelligent-Internet/ii-agent.git
cd ii-agent

# 2. Run first-time setup (creates .env files + installs deps)
make setup

# 3. Configure your LLM API keys
#    Edit .env and set at least one LLM provider:

#    Option A: Inline JSON in .env
#    MODEL_CONFIGS='[{"model_id":"claude-sonnet-4-6","provider":"Anthropic","api_key":"sk-ant-...","display_name":"Claude Sonnet 4","is_default":true}]'

#    Option B: YAML config file
#    Copy model_configs.example.yaml to model_configs.yaml, fill in your keys,
#    then set MODEL_CONFIGS_FILE=model_configs.yaml in .env

# 4. Start everything (infra + backend + frontend)
make dev-all

This starts:

• Backend at http://localhost:8000
• Frontend at http://localhost:1420
• PostgreSQL at localhost:5432
• Redis at localhost:6379
• MinIO (S3-compatible storage) at http://localhost:9001 (minioadmin/minioadmin)

Configuration Files

File	Created from	Purpose
.env	.env.example	Backend config: database, Redis, storage, auth, LLM keys
frontend/.env	frontend/.env.example	Frontend config: API URL, Google OAuth, theme
model_configs.yaml	model_configs.example.yaml	LLM model definitions (alternative to inline JSON in .env)

LLM Providers

II-Agent supports multiple LLM providers. Configure them in model_configs.yaml or via MODEL_CONFIGS in .env:

Provider	Example model_id	Notes
OpenAI	gpt-5.4	Requires api_key
Anthropic	claude-opus-4-6	Direct API or Vertex AI
Google	gemini-3.1-pro-preview	Direct API or Vertex AI

See model_configs.example.yaml for full configuration options including Vertex AI, Azure, and self-hosted models.

Useful Make Commands

make help             # Show all available commands
make dev-all          # Start everything (infra + backend + frontend)
make infra            # Start only Postgres, Redis, MinIO
make backend-dev      # Start backend only (port 8000)
make frontend-dev     # Start frontend only (port 5173)
make db-migrate       # Run database migrations
make lint             # Lint backend + frontend
make format           # Auto-format backend + frontend
make test             # Run all tests
make stack            # Start full stack via Docker Compose

Docker Compose (Full Stack)

To run everything in Docker (no local Python/Node required):

# Copy and edit the stack env file
cp docker/.stack.env.example docker/.stack.env
# Edit docker/.stack.env with your credentials

make stack            # Start full stack
make stack-build      # Start with --build (rebuild images)
make stack-down       # Stop and clean up
make stack-logs       # Tail all logs
