What is Vald?
Vald is a cloud-native vector search platform running on Kubernetes that uses NGT for efficient nearest-neighbor search. It provides automatic indexing and backups, index replication across distributed agents, and horizontal scaling to handle billions of vectors.
What Vald does
The capabilities that matter for vector databases, normalised so it lines up with every alternative. “-” means we haven't confirmed it, not that it's missing.

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Vald, not the verdict.
