Memory infrastructure for AI agents and applications, available as an open-source framework and managed platform.
Mem0 is best for developers adding persistent memory to AI agents because it combines an open-source framework with hosted plans from a free Hobby tier to $19 Starter, $79 Growth, $249 Pro, and custom Enterprise pricing, so teams can test memory workflows cheaply before choosing managed scale or private deployment. The core value is narrower and more practical than a generic retrieval stack: Mem0 is designed to decide what should become memory, attach it to users, agents, or sessions, and make that context searchable for future interactions. That matters for assistants, copilots, customer-support agents, and multi-session products where the model should remember durable preferences, prior problems, account context, or long-running task state without forcing the application team to rebuild a memory service from raw embeddings and database primitives.
The pricing facts in this record make the hosted path concrete: Hobby is listed at $0/month with unlimited end users, 10,000 add requests per month, 1,000 retrieval requests per month, 1 project, and community support; Starter is $19/month with 50,000 add requests, 5,000 retrieval requests, 1 project, and community support; Growth is $79/month with 200,000 add requests, 20,000 retrieval requests, 3 projects, email support, and basic analytics; Pro is $249/month with 500,000 add requests, 50,000 retrieval requests, unlimited projects, private Slack support, and advanced analytics; Enterprise is custom priced with unlimited add and retrieval requests, unlimited projects, private Slack plus SLA, audit logs, custom integrations, SSO, and on-prem deployment. Those quotas also explain the buying path: Hobby is mainly for testing, Starter and Growth fit smaller production workloads, Pro is for higher-volume hosted use, and Enterprise is where compliance, private deployment, custom integrations, and stronger support become the decision drivers.
