Letta Code: a memory-first coding agent

I work at Letta.

Letta Code is a big release for us, and it is a fundamentally different approach to coding agents with a focus on continual learning and statefulness.

One agent per project, specialized, infinitely lived. No more compactions, no more forgetting.

Letta Code is our first non-platform product. We built it on top of our developer platform using our SDK. It is a showcase of what you can do with Letta.

Charles (OP) built a quick prototype a few months ago, and we've been allocating more and more time towards making it a product that we feel comfortable using internally over other options like Claude Code or Codex.

Letta Code is fundamentally different from every other coding agent in that the agent runs on a server, not your machine. These agents are infinitely long-lived "people in a box" that develop specializations as you use them. They don't just die.

The team has been increasingly more excited and invested in Letta Code. All of us see exactly how powerful stateful agents are when deployed in code environments, and it's been amazing watching everyone pull together and make something insanely cool.
