Zep is cloud-based and expensive. Here are the best open-source alternatives with local-first privacy.
Zep's pricing starts at $40/mo for individuals and $249/mo for teams. Several open-source alternatives offer comparable features with free tiers.
Squish (local-first, free, MCP-native), Mem0 (cloud with free tier), Letta (stateful agents), and Engram (ultra-lightweight) each solve agent memory differently.
Prioritize local-first if privacy matters. Choose MCP-native if you want plug-and-play integration. Pick based on your stack and team size.
