Agent Development Environment (ADE)

Tip

You run the ADE locally with Letta Desktop, or via https://app.letta.com where you can connect it to your own Letta Docker deployment. Read more about the ADE on our blog post.

What is the ADE?

The Agent Development Environment (ADE) is a visual interface for creating and managing stateful agents. Use the ADE to design, test, and monitor your agents while getting direct visibility into their memory state and decision-making process.

Unlike simple chatbot interfaces, the ADE gives you complete control over your agent’s state across its entire lifecycle:

• Create and customize agents without writing code
• Visualize your agent’s memory and context window in real-time
• Add and test custom tools in a sandboxed environment
• Monitor agent behavior and performance

The ADE provides a graphical interface to agents running in your Letta server. These same agents can be accessed via the Letta APIs, allowing you to integrate them into your applications.
