- Group-based access control — Fine-grained tool access by user groups
- Audit logging — Track every query per user for compliance

### Modern Web Interface

- Pre-built <vanna-chat> component — Drop into any webpage (React, Vue, or HTML)
- Streaming responses — Real-time tables, charts, and progress updates via SSE
- Framework-agnostic — Works with your existing auth (cookies, JWTs, OAuth)
- Customizable themes — Light/dark modes, responsive design

### Production-Ready Architecture

- FastAPI/Flask servers included — Production backends out of the box
- Modular tool system — Extend with custom Tool classes
- Lifecycle hooks — Quota checking, logging, content filtering
- Observability built-in — Tracing and metrics integration
- LLM agnostic — OpenAI, Anthropic, Ollama, Azure, Gemini, Bedrock, Mistral, and more
