Zep alternatives in detail
Letta
freemiumApache-2.0Web, macOS, Windows, LinuxPlatformLetta (formerly MemGPT, Apache-2.0, ~25k stars) builds agents that manage their own memory — self-editing memory blocks, conversation search, persistence beyond any context window — exposed as an agents server/API with Python/TS SDKs and a visual Agent Development Environment. Its March 2026 pivot made Letta Code the flagship: a memory-first, model-agnostic coding harness.
Mem0
open sourceApache-2.0SDKMem0 adds a persistent memory layer to agents and LLM apps: it extracts, stores, and retrieves salient facts across sessions so an assistant remembers a user's preferences and history instead of starting cold each conversation. Open-source library plus a managed platform.
