Hunta Gather vs Zep: where each one wins.
Most pages written for the search "Zep alternative" never concede a point. This one does. If Zep is the right memory store for you, we say so below, and we show the rows where we are behind.
Choose Hunta Gather
if you need to know what your agents are allowed to store, want isolation you can check rather than trust, and want a price that starts at zero and grows per seat. Bi-temporal is live in its honest form, with the last piece on the roadmap.
Different centres of gravity. Zep optimises what the graph knows. Hunta Gather optimises what is allowed in, and whether you can prove the boundary around it.

Where Zep is stronger
No spin on these three
- Bi-temporal depth. Zep's Graphiti keeps two clocks per fact: when it was true in the world and when the system learned it, with automatic invalidation. It is the reference implementation, released as an open-source library with about 31,000 GitHub stars. We keep history and answer as-of queries today, and event-time precedence is on our roadmap, not shipped.
- Compliance and enterprise deployment. Zep's Enterprise tier lists SOC 2 Type II, a HIPAA BAA, audit logs, a one-year API log, and deployment in your own cloud with your own keys. We hold no certification today. Our data processing agreement is public on every tier, and self-hosting is an Estate conversation.
- Scale and benchmarks. Zep publishes LongMemEval and LoCoMo results and has analyst coverage. Our internal benchmark number is not published yet, and we will not quote it until it is.
Where Hunta Gather wins
Three things Zep does not do
- Reviewed writes. Every memory an agent proposes waits in a review queue before the store accepts it. A planted instruction in a web page cannot become a trusted fact on its own. Zep's controls decide what each agent may read. They do not review what enters.
- Isolation you can verify. One schema per tenant, row-level security in force mode, and a per-tenant encryption key, probed adversarially and signed into an Ed25519 receipt you verify offline against our published key. Zep isolates per project and role, and offers your own cloud at Enterprise, but there is no receipt to run.
- Price and shape. Scout is free. Tribe is $25 per seat per month with no minimum, tokens metered. Zep's self-serve plans start at $125 per month for 50,000 credits, metered per episode, with a 10,000-credit free tier for prototyping.
On bi-temporal, specifically
Zep's headline, said plainly
Zep's temporal model is more complete than ours right now. Hunta Gather supersedes facts instead of overwriting them, keeps the full history, and answers what you knew as of any date. Choosing the winning fact by when it was true in the world, not just by when you learned it, is on our roadmap. What we add is different: those facts sit on a write path that reviews every entry and inside an isolation boundary you can prove. That combination is ours.
