nao

The #1 Open-Source Analytics Agent

🌐 Website · 📚 Documentation · 💬 Slack

What is nao?

nao is a framework to build and deploy analytics agent.
Create the context of your analytics agent with nao-core cli: data, metadata, modeling, rules, etc.
Deploy a UI for anyone to chat with your agent and run analytics on your data.

Key Features

For data teams:

• 🧱 Open Context Builder — Create a file-system like context for your agent. Add anything you want in the context: data, metadata, docs, tools, MCPs. No limit.
• 🏳️ Data Stack Agnostic — Works with any data warehouse, stack, type of context, LLM.
• 🕵🏻‍♀️ Agent Reliability Visibility — Unit test your agent performance before deploying it to users. Version the context and track the performance of your agent over time. Get users feedbacks to improve the agent and track their usage.
• 🔒 Self-hosted & secure — Self-host your analytics agent and use your own LLM keys to guarantee maximum security for your data.

For business users:

• 🤖 Natural Language to Insights — Ask questions in plain English, get analytics straight away
• 📊 Native Data Visualization — Create and customize visualizations directly in the chat interface
• 🧊 Transparent Reasoning — See the agent reasoning and sources clearly
• 👍 Easy Feedback — Send feedback to the data team when a answer is right or wrong

⚡️ Quickstart your agent in 1 minute

• Step 1: Install nao-core package

    pip install nao-core
    

• Step 2: Initialize a nao project

    nao init
    

It will ask you:

• To name your project
• If you want to connect a database _(optional)_
• If you want to add a repo in agent context _(optional)_
• To add an LLM key _(optional)_
• If you want to setup a Slack connection _(optional)_

💡 You can skip any optional question and configure them later in your nao_config.yaml file.

This will create:

• A new folder with your project name
• An architecture for your context files
• A nao_config.yaml configuration file
• A RULES.md file

• Step 3: Verify your setup

cd to the project folder and run:

    nao debug
    

• Step 4: Synchronize your context

    nao sync
    

This will populate your context folder with your context files (data, metadata, repos, etc.)

• Step 5: Launch the chat and ask questions

    nao chat
    

This will start the nao chat UI. It will open the chat interface in your browser at http://localhost:5005. From there, you can start asking questions to your agent.

Evaluation framework

Unit test your agent performance before deploying it to users. First, create a folder tests/ with questions and expected SQL in yaml. Then, measure agent's performance on examples with nao test command:

nao test

View results in tests panel:

nao test server
