Overview

Memory-first coding agent and SDK for persistent agents that learn over time, work locally or remotely, and can be embedded into agentic coding applications.

Details

Letta Code is Letta’s memory-first coding agent and SDK for building or using persistent coding agents that remember and learn over time. Letta’s docs describe it as “the memory-first coding agent that remembers and learns,” with documentation for quickstart, CLI, memory, skills, and API usage. The CLI docs state that Letta Code runs from the terminal, supports Letta Cloud agents and Local mode, and installs with npm. The quickstart covers desktop, CLI, and cloud setup, including model-provider connection, default agent selection, remote tool execution, memory commands, search, and multi-threaded conversations.

When to Use

Use when you want a coding agent designed around long-lived, persisted agents that can remember and learn over time. Use when you need a terminal-based coding workflow that can use Letta Cloud agents or Local mode. Use when building agentic coding applications that need an embeddable memory-first coding agent or SDK. Use when evaluating workflows that include memory commands, remote tool execution, search, or multi-threaded conversations.

Getting Started

  1. Visit the Letta Code product page for the product overview.
  2. Follow the official Letta Code quickstart for desktop, CLI, and cloud setup.
  3. Install the CLI as documented with npm install -g @letta-ai/letta-code.
  4. Connect a model provider and select a default agent as described in the quickstart.
  5. Review the GitHub repository before adopting it in a project.
