Accessing the web ADE

The web ADE is available at https://app.letta.com. You can use the browser-based ADE to connect to both Letta Cloud, and agents running on your own Letta deployments.

Understanding Connection Types

The ADE can connect to different types of Letta servers:

1. Local Server: A Letta server running on your local machine (localhost)
2. Remote Server: A self-hosted Letta server running on a remote address
3. Letta Cloud: Letta’s managed cloud service for hosting agents

All connections use the Letta REST API to communicate between the ADE and the server. For remote servers (non-localhost), HTTPS is required.

Connecting to a Local Server

Connecting to a local Letta server is the simplest setup and ideal for development:

1. Start your Letta server using Docker
2. Access the ADE by visiting https://app.letta.com
3. Select “Local server” from the server list in the left panel

The ADE will automatically detect your local Letta server running on localhost:8283 and establish a connection.

Connecting to a Remote Server

For production environments or team collaboration, you may want to connect to a Letta server running on a remote machine:

Danger

The cloud/web ADE does not support connecting to http (non-https) IP addresses, except for localhost.

For example, if your server is running on a home address like http://192.168.1.10:8283, the ADE (when running on a browser on another device on the network) will not be able to connect to your server because it is not using https.

For more information on setting up https proxies, see the remote deployment guide.

To connect to a remote Letta server:

1. Deploy your Letta server on your preferred hosting service (EC2, Railway, etc.)
2. Ensure HTTPS access is configured for your server
3. In the ADE, click “Add remote server”
4. Enter the connection details:
   • Server name: A friendly name to identify this server
   • Server URL: The full URL including https:// and port if needed
   • Server password: If you’ve configured API authentication, enter the password

Managing Server Connections

The ADE allows you to manage multiple server connections:

Saving Server Connections

Once you add a remote server, it will be saved in your browser’s local storage for easy access in future sessions. To manage saved connections:

1. Click on the server dropdown in the left panel
2. Select “Manage servers” to view all saved connections
3. Use the options to edit or remove servers from your list

Switching Between Servers

You can easily switch between different Letta servers:

1. Click on the current server name in the left panel
2. Select a different server from the dropdown list
3. The ADE will connect to the selected server and display its agents

This flexibility allows you to work with development, staging, and production environments from a single ADE interface.
