Is Graphiti open source?

Yes, Graphiti is Apache 2.0. Zep Cloud is proprietary.

omnia vs zep

Zep stores what the agent learns. Omnia redacts it before it’s stored.

Omnia’s memory runs in your own cluster, as part of the platform that runs the agent, and redacts personal data before it’s stored. Zep is a temporal knowledge graph that invalidates old facts as new ones arrive.

A caller reads out their card number while asking about a refund.

on omnia

The session recording keeps the refund request with the number redacted, and the redactor runs again before anything is committed to long-term memory. The agent remembers that this customer asked for a refund. docs

on zep

Content policies are in closed beta, aren’t available for BYOC, and don’t filter, redact or rewrite the text you send. their docs

Redaction before memory

Replace, hash or mask detected values, or encrypt them, before they reach the session or memory. A built-in self-test writes a test card number and fails if it comes back readable. docs enterprise

Zep: Content policies flag; they don’t redact. source

Self-hosted, supported

Memory runs on Postgres and pgvector in your cluster, as part of a platform you install with Helm. docs

Zep: Community Edition is deprecated and no longer supported; BYOC runs inside your VPC. source

Withdrawing consent

When a user withdraws consent, it applies to memories already stored. Erasure runs as a data subject request, with each step in the audit trail. docs enterprise

Zep: Deleting a user cascades to their threads and graph, asynchronously. source
