GoodMemory vs letta
GoodMemory: GoodMemory provides a durable memory layer for AI products, chat apps, copilots, and coding agents, enabling a continuous user/project memory loop. It offers APIs to write, retrieve, inject, audit, and delete context, serving as the product memory layer between applications and model runtimes.; letta: Letta is a powerful platform for building stateful AI agents equipped with advanced memory, enabling them to learn and self-improve over time. It provides both a command-line interface for local agent execution and a comprehensive API with Python and TypeScript SDKs for seamless integration into applications.

TL;DR

Integrate into an Agent, Chatbox, or Copilot: build memory functionality directly into your Node/Bun service for managing context in chat applications or copilots.
lettaMemory & Context · ★ 25.2k
When to choose:
- You want a long-lived agent that remembers past work and rewrites its own memory and context over time.
- You want one agent reachable from CLI, desktop, browser, mobile and messaging apps, with subagents, schedules and hooks.
- You want memory you can inspect: the README says context is tracked in git and can sync to your own repository.
When to skip:
- You only need to add memory to an agent you already use through MCP; a small MCP memory server is a lighter fit.
- You rely on older Letta tutorials or the V1 API server: the project restructured, and the V1 server is retired.
- You want everything to work without signing in: Letta Cloud is the default backend and some features need it.

Use Cases
GoodMemory↳Integrate into an Agent, Chatbox, or Copilot: build memory functionality directly into your Node/Bun service for managing context in chat applications or copilots.
↳Add Memory to Codex or Claude Code: enhance installed coding agents with persistent project and user context without modifying the agents themselves.
↳Deploy as a Backend Memory-Layer Service: use as a standalone backend service, especially for Python/FastAPI backends, to centralize memory storage and management.
↳Autonomous Agent Memory: enable autonomous agents to manage their own durable, cross-session memory by integrating the GoodMemory CLI or API.
letta↳Running AI agents locally in your terminal for coding and general tasks.
↳Integrating stateful AI agents into custom applications using the API and SDKs.
↳Developing self-improving AI systems that adapt and learn continually.
