Accessing the web ADE
Connect to both self-hosted and cloud agents from 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:
- Local Server: A Letta server running on your local machine (
localhost
) - Remote Server: A self-hosted Letta server running on a remote address
- 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:
- Start your Letta server using Docker
- Access the ADE by visiting https://app.letta.com
- 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:
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:
- Deploy your Letta server on your preferred hosting service (EC2, Railway, etc.)
- Ensure HTTPS access is configured for your server
- In the ADE, click “Add remote server”
- 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:
- Click on the server dropdown in the left panel
- Select “Manage servers” to view all saved connections
- Use the options to edit or remove servers from your list
Switching Between Servers
You can easily switch between different Letta servers:
- Click on the current server name in the left panel
- Select a different server from the dropdown list
- 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.
