Letta Code Letta Code
Letta Code is a memory-first coding agent harness that provides persistent, stateful agents capable of learning from experience over long time horizons. Unlike session-based coding tools, it maintains an editable memory layer that persists across model swaps and multi-day coding sessions.
Launched the Letta Code desktop app in April 2026 and integrated messaging Channels in May 2026, consolidating the platform's offering around the memory-first coding CLI.
As of
- Tiered memory architecture (core, archival, and recall)
- Automatic model routing via Letta Auto (Auto Chat and Auto Fast variants)
- Skill learning and self-improvement through memory blocks
- Model-agnostic design with hot-swappable LLM support
- Cross-environment execution via CLI, desktop app, and remote sandboxes
Developers building coding agents that need to learn project-specific patterns, conventions, and architectural history across many sessions.
Users seeking lightweight or fire-and-forget task automation, or those who find manual management of agent memory systems to be unnecessary overhead.
Free tier available for up to 3 managed agents with BYOK. Pro plan is $20/month for up to 20 stateful agents with Letta Auto usage quotas and pay-as-you-go overages. Developer API plans start at $20/month plus usage-based fees.
A powerful, memory-first solution for developers fighting AI amnesia in coding workflows, though it requires a steeper learning curve than stateless tools due to the complexity of its persistent memory system.
