When to consider an alternative: Use Zep when relationships between facts matter. If your only need is semantic search over docs, a vector database is simpler.

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?
