Choose Mem0 if...

Choose Zep if...
- temporal memory
- knowledge graphs
- agent recall
Not ideal if...
- small prototypes that only need session history
- teams unwilling to model memory permissions
custom graph memory
Custom or external option
Choose custom graph memory if...
- Choose this path if you need a narrow internal solution, a lower-level primitive, or a tool outside this directory.
Not ideal if...
- Not ideal if you still need a maintained product profile, docs trail, and comparable evaluation criteria.
What to consider
- Does the alternative solve the same agent layer, or is it a lower-level building block?
- Will switching improve observability, permission boundaries, state control, or evaluation coverage?
- Can the team validate the migration with one real agent task before replacing the current tool?
