Both are open source memory options with comparable terms, so the choice comes down to which model of the problem you prefer — compare the descriptions below rather than the licence.
Treats memory as a reasoning problem, not a retrieval one — you ask its Dialectic API a question about the user and get a synthesised answer.

A messages table and a summaries table. Boring, auditable, yours.
Start here. Move to a memory product when you can name the query it makes fast.
