Free alternatives to Zep
2 free programs that can replace Zep, each pairing checked by Radar's AI reviewer or by Radar.
Zep is a service from the company Zep that developers use as a memory layer for AI assistants and agents, so that an application can remember earlier conversations and facts about a user. It is aimed at people building their own AI applications rather than at end users, and the hosted version is offered as an online service with plans.
Before switching, work out how your application talks to the current service. Check the programming languages and libraries the alternative supports, how it stores and searches what it remembers, and whether you can export the data you already have and load it into the new system. Think about where the data will live: on your own servers or with an outside company, especially if it contains personal information from your users. Compare how long it takes to answer a request, how it behaves as the amount of stored memory grows, and how well documented and maintained the project is.
Hindsight is the option listed below. Run a small test with real conversations before you move production traffic.
