Microsoft Azure's managed service for PostgreSQL, which supports the pgvector extension, enabling robust vector database capabilities in the cloud for AI and machine learning workloads.

PostgreSQL-compatible distributed database with pgvector support and USearch integration, proven to handle billions of vectors with 96.56% recall and sub-second query latency.

PostgreSQL extension for scalable, high-performance vector search, successor to pgvecto.rs. Features RaBitQ quantization enabling 6x cost savings vs Pinecone. Fully compatible with pgvector. This is an OSS extension.

Google Cloud's fully managed, PostgreSQL-compatible database service that offers vector capabilities, leveraging the power of PostgreSQL and pgvector for AI applications.

Serverless Postgres with native pgvector support for vector embeddings and similarity search. Features instant provisioning, autoscaling, and scale-to-zero with separated compute and storage. This is a commercial managed service with free tier.

Managed PostgreSQL service from AWS with pgvector extension for vector embeddings and similarity search. Features include storage auto-scaling, read replicas, Multi-AZ high availability, and Row Level Security (RLS) enabling secure multi-tenant AI applications. Combines full SQL power and ACID transactions with vector capabilities, superior to dedicated vector DBs for complex relational queries and joins.

Managed serverless Postgres with pgvector for vector similarity search, featuring real-time subscriptions, Edge Functions, auto-HNSW indexing, serverless scaling, and RLS for multi-tenant isolation. Built for full-stack AI apps with auth, storage, and realtime. Postgres SQL + vectors outperforms dedicated DBs in integrated app development and cost for RAG/multi-tenant use cases.

AlloyDB for PostgreSQL offers managed vector storage and search for AI workloads on Google Cloud, with optimized HNSW indexing. It supports serverless scaling, hybrid vector-relational queries, and integrations with Google Cloud ecosystem and pgvector. Suited for RAG pipelines and enterprise AI requiring ACID compliance, it provides superior performance and management ease versus self-hosted databases like Milvus.

An AWS database service compatible with PostgreSQL, identified as a great choice for vector database needs.

A managed service for PostgreSQL that includes support for pgvector, enabling PostgreSQL to function as a vector database for AI workloads.

Serverless data platform built on PostgreSQL with integrated vector search, full-text search engine, and ChatGPT capabilities, providing type-safe SDKs and database branching for modern applications.

PostgreSQL extension enabling fast full-text, faceted, and hybrid search over Postgres tables using the BM25 algorithm. Built on Tantivy for production-ready search with ACID guarantees and transactional consistency.

DiskANN-inspired index type in pgvectorscale optimized for disk-based storage with streaming updates, enabling billion-scale vectors with limited memory.

Lightweight WASM Postgres build packaged into a TypeScript client library that enables running PostgreSQL in the browser, Node.js, Bun, and Deno with pgvector support. At only 3MB gzipped, it provides full Postgres functionality including vector search capabilities without requiring separate database installation.
