CoreWeave Launches Managed PostgreSQL Service That Runs Inside Its Kubernetes Clusters
LIVINGSTON, N.J. -- CoreWeave on Wednesday announced the general availability of CoreWeave Database, a managed PostgreSQL service that runs inside customers’ CoreWeave Kubernetes Service (CKS) clusters alongside their training and inference workloads. The launch landed during KubeCon + CloudNativeCon North America 2026 week and is built on CloudNativePG (CNPG), the open source Kubernetes operator for Postgres that CNCF moved to incubation this week.
Keeping State Next to the GPUs
CoreWeave said teams building on its cloud previously either operated PostgreSQL themselves or kept it in another cloud, which added a network hop, an egress path and a second environment to secure. Databases now run on CPU nodes in the customer’s CKS cluster and connect through an in-cluster Kubernetes service. Each database runs a primary instance with read replicas spread across hosts, automatic failover and live data stored on CoreWeave Distributed File Storage. Continuous backups are on by default, with point-in-time recovery, scheduled and on-demand backups and full restores to a new cluster for validation.
“AI in production runs on more than GPUs. It runs on the application state, metadata, and embeddings that agents and training pipelines touch on every step,” said Corey Sanders, senior vice president of product at CoreWeave. “CoreWeave Database puts that data in the same cluster as the compute that depends on it, operated by CoreWeave so teams can spend their time on models instead of database operations.”
Security, Vector Search and CNPG
Databases stay private to the cluster and are encrypted at rest and in transit, with CoreWeave managing TLS certificates and security patches. Customers control access through native PostgreSQL roles, Kubernetes network policies and audit logging. The service supports pgvector, so teams can store embeddings and run vector search for retrieval-augmented generation in the same database as their application data. CNPG handles primary and replica management and failover, while CoreWeave adds console and Kubernetes workflows, managed backups, monitoring and ongoing operations. The company also cited upstream contributions, including S3 compatibility improvements in the Barman backup tool and connection configuration work in the pgexporter Prometheus exporter.
CoreWeave Database is fully PostgreSQL compatible, so existing databases can be migrated with native Postgres tools. It is generally available now. Pricing was not disclosed.
