Mem0
Default hosted agent memory bolt-on. Model retrieval volume carefully; self-host OSS if caps hurt. Strengths: Drop-in agent memory API; OSS + hosted; Fast prototype path.
Strengths
- Drop-in agent memory API
- OSS + hosted
- Fast prototype path
Weaknesses
- Retrieval metering surprises
- Graph gated to higher tiers
- Not a full vector DB
Zep
Pick when agents need temporal/entity graph memory, not just vector snippets. Mem0 for simpler recall. Strengths: Temporal graph memory; Strong for relational recall; OSS Graphiti path.
Strengths
- Temporal graph memory
- Strong for relational recall
- OSS Graphiti path
Weaknesses
- Credit model needs modeling
- Heavier than Mem0 for simple recall
- Graph ops complexity if self-host
