# Mem0: Pricing, Features & Alternatives

Mem0 adds long-term memory to an existing agent: it extracts facts from conversations and retrieves the relevant ones with combined semantic, keyword and entity search. It is the most-starred project in the category (about 67K GitHub stars) and runs as a Python or npm library, a self-hosted Docker server or a managed platform. In April 2026 Mem0 reported 92.5 on LoCoMo and 94.4 on LongMemEval for its managed platform; those are its own numbers, and it says open-source results will be similar but not identical. Platform: Hobby free (10K add and 1K retrieval requests a month), Starter $19/month, Pro $249/month with graph memory, Enterprise custom with on-prem.
