PlatformAccount requiredfreemiumglobal

Letta is an open-source platform that helps developers and AI engineers build agents with persistent memory, reasoning, and access to a large library of tools. It addresses issues of agents losing context and vendor lock-in by offering self-hostable software with built-in memory and tool support. The product is offered on a freemium basis for teams focused on agent development rather than non-AI workflows.
