Installing Letta Desktop

Trying Letta for the first time? Follow our Letta Code or API quickstart to learn the basics first. Letta Desktop requires a running Docker server, which requires additional setup and debugging work.

If you’re looking for an open source frontend for Letta, check out Letta Cowork, an OSS example desktop app powered by the Letta Code SDK.

Download Letta Desktop

Letta Desktop is not a standalone application, and requires a running Letta server running separately, either via the Letta API, or via Docker.

Letta Desktop is a frontend - without a separate server, you will not be able to create, view, or interact with any agents.

Letta Desktop is currently in beta and may be unstable. For questions and support, join our community Discord server.

Letta Desktop allows you to run the ADE (Agent Development Environment) as a local application. Download the latest installer for your platform below:
