What is Rivestack?

Rivestack is a managed PostgreSQL service built specifically for AI and vector search workloads. Every instance comes with pgvector pre-configured on NVMe storage, with HNSW indexes tuned out of the box. Unlike general-purpose database platforms that bolt on vector search as one of many features, Rivestack focuses entirely on giving developers fast, affordable pgvector without the operational overhead. Key details:

Dedicated PostgreSQL 18 with pgvector 0.8 on NVMe storage 2,000 QPS vector search at sub-4ms latency on the $29/month plan Automated daily backups with 14-day point-in-time recovery HA support with Patroni — add nodes at the same price Terraform provider for infrastructure-as-code workflows EU (Germany) and US-East regions Free tier for testing and prototyping

Pricing starts at $0 for a shared cluster and $29/month for a dedicated single-tenant instance with 2 vCPU, 4 GB RAM, and 55 GB NVMe storage. No per-query fees, no bandwidth charges.
