Connecting to the ADE
The following instructions are for the cloud/web ADE. If you are using the ADE via Letta Desktop, the ADE will automatically open and connect to localhost:8283
when you run the app.
The ADE can connect to self-hosted Letta servers (e.g. a Letta server running on your laptop), as well as the Letta Cloud service. When connected to a self-hosted / private server, the ADE uses the Letta REST API to communicate with your server.
Connecting to a local server
To connect the ADE with your local Letta server (running on localhost
), simply:
- Start your Letta server (
docker run ...
) - Visit https://app.letta.com and you will see “Local server” as an option in the left panel


Connecting to an external (self-hosted) server
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 on https
.
For more information on https
proxies, see this page.
If your Letta server isn’t running on localhost
(for example, you deployed it on an external service like EC2):
- Click “Add remote server”
- Enter your desired server name, the IP address of the server, and the server password (if set, otherwise leave empty)
Note that the remote IP address must be https
, or the ADE will not be able to connect.
