Best alternatives to Mem0 in 2026
Talk to most AI chatbots twice and they won't remember anything from the first conversation — every session starts from zero unless a developer builds custom memory logic themselves. Mem0 is a plug-in memory layer that solves that: it stores what a user told an AI agent, what it learned about their preferences, and past interactions, then feeds the relevant pieces back in on future conversations, the way a good assistant remembers your usual coffee order without being told again each time. Mem0 is an open-source (Apache 2.0) memory infrastructure layer for AI agents and applications, combining vector, graph and episodic memory to persist context across sessions. With 61,000+ GitHub stars, it's the most widely adopted project in this space and is the exclusive memory provider integrated into AWS's Agent SDK, with published integrations for Anthropic's SDK, OpenAI's Agents SDK and Google's ADK. Pricing runs Hobby (free, 10K memory-add requests/month), Starter ($19/month, 50K add requests), Pro ($249/month, 500K add requests, unlimited projects, graph memory, Slack support), and custom Enterprise with on-prem deployment, SSO and SLA support. It's SOC 2 Type 1 and HIPAA compliant, and reports over 90,000 developers building on it.
