Rivestack - 2026 Pricing, Features, Reviews & Alternatives

Rivestack is a cloud-based managed PostgreSQL service with pgvector pre-installed and tuned on dedicated NVMe hardware, targeting developer teams and small-to-medium AI product teams building retrieval-augmented generation (RAG) pipelines, semantic search, and recommendation systems. Vectors and relational data share a single transactional store, removing the operational overhead of running and synchronizing a separate vector database. Instances run on dedicated single-tenant VMs with local NVMe storage rated at 500K+ IOPS, eliminating the IOPS bottlenecks that affect HNSW traversal on standard cloud SSDs. All new instances default to PostgreSQL 18 with HNSW and IVFFlat index support pre-configured, so no manual tuning is required before the first query.

The platform provides Patroni-managed high-availability clusters with streaming replication and automatic failover, automated daily backups with 14-day retention, and point-in-time recovery to any second. Automatic text-to-vector embedding on insert is available via OpenAI text-embedding-3-small (1536 dimensions), and hybrid search combines vector similarity with PostgreSQL full-text search (tsvector, pg_trgm) in a single SQL query. PgBouncer connection pooling, a per-database metrics dashboard, an AI-assisted SQL query generator, and a row browser with inline filters and keyset pagination are included in the dashboard. The service is compatible with Python, Node.js, Go, Java, Rust, Ruby, .NET, and any standard PostgreSQL client.

Rivestack is deployed across EU Central, US-East, and Singapore regions, with EU-by-default data residency for GDPR compliance. A shared tier supports development and testing workloads; dedicated single-tenant VMs serve production requirements. Pricing follows a flat per-node model with no per-query billing, no egress surcharges, and no vector-count overages. A free tier is available with no credit card required, and free migration assistance is included for teams moving from Supabase, Neon, or Pinecone.
