Is ZeptoDB Community really free?
Yes. Community includes the full single-node time-series core, SQL, HTTP API, Python DSL, Arrow Flight, Parquet HDB, and Agent Memory v0. Many teams use it for prototypes, pilots, and single-node production systems.
What requires an Enterprise license?
Multi-node time-series clustering, SSO/OIDC, audit log export, advanced RBAC, Kafka connector, migration tools, geo-replication, rolling upgrades, LTS releases, and priority support.
Is Agent Memory cluster-wide today?
No. Agent Memory v0 is single-node. In a cluster, route /api/ai/* to a sticky pod or treat it as a per-pod cache. Cluster-consistent memory routing and replicated memory writes are follow-up work.
Does ZeptoDB call LLM or embedding providers?
No. Applications supply embeddings and call model providers. ZeptoDB stores memory records, ranks candidates, assembles context, and performs exact/semantic cache lookup.
How does license validation work?
Fully offline — RS256 signature verification with no phone-home. Load via environment variable (ZEPTODB_LICENSE_KEY), file (/etc/zeptodb/license.key), or HTTP API (POST /admin/license).
What happens when a license expires?
You get a warning before expiry, then a grace period where the deployment continues working. After the grace period, the instance downgrades to Community edition. No data is locked.
