pgvector overtakes Qdrant as Claude's #1 pick
for vector database for production ai apps
Qdrant→pgvector
On 2026-07-13, Claude changed its #1 recommendation for best vector database for production ai apps — dropping Qdrant from the top spot in favor of pgvector. The previous #1 had held since 2026-07-12.
“For the typical practitioner, most production vector workloads (up to tens of millions of vectors) fit in the Postgres they already run — you get ANN search plus real transactions, joins, and metadata filtering in one system with zero new infrastructure, and HNSW support plus extensions like pgvectorscale closed most of the performance gap; assumption shaping the rank: the median AI app's corpus is small enough that operational simplicity outweighs peak ANN throughput”— Claude
