Installation

This guide will walk you through installing the Dexto CLI and setting up your environment so you can start running agents.

Prerequisites

• Node.js >= 20.0.0
• An LLM API Key:
  • Get an OpenAI Key
  • Get a Gemini Key
  • Get a Claude Key
  • Get a Groq Key

1. Install Dexto

Install Dexto globally using npm:

npm install -g dexto

This adds the dexto command to your system, giving you access to the agent runtime.

2. Run dexto for the first time

dexto

This triggers the first time setup, where you will be asked to set up your preferred Large Language Model (LLM) and enter the API key.

Once setup is complete, you should see a terminal UI open, you can now interact with your first dexto agent! Say hi!

Note: You can re-run the setup at any time with the command dexto setup

Next Step: Build Your First Agent

Now that Dexto is installed, you're ready to create your first custom agent with its own configuration and capabilities.
