What each one is
Letta
Letta (formerly MemGPT) is a framework and server for building stateful agents with long-term memory that persists across sessions, with a visual agent editor.
- Persistent long-term agent memory
- Server with REST API and visual editor
- Model-agnostic and self-hostable
OpenClaw
OpenClaw is a personal AI assistant designed to run on any operating system and connect to whichever model provider you choose, rather than being tied to one vendor. Note on its licence: GitHub reports it as unrecognised, but the LICENSE file is the standard MIT text — it was edited enough that automatic detection fails.
- Runs on any OS rather than a single desktop platform
- Provider-independent: you choose the model behind it
- Very large and active community
