In their own words
Azure Cosmos DB for NoSQL
Azure Cosmos DB for NoSQL is a fully managed cloud database built around schema-agnostic JSON documents and SQL-like querying. It supports global data distribution, multi-region writes, and automatic failover, with configurable consistency controls and transactions. Search includes vector and hybrid similarity capabilities for workloads such as retrieval-augmented generation and AI agents. Throughput can use standard provisioned, autoscale provisioned, or serverless models. The service lists SDKs for.NET, Java, JavaScript/Node.js, Python, Go, and Rust. Its change feed can support event-driven architectures and streaming pipelines using Azure Functions and Spark; no-ETL analytical workflows are available through Azure Synapse Link or Fabric mirroring. Microsoft states that NoSQL data has service-level agreements including less than 10 millisecond read and write latency and 99.999 percent availability. A free tier includes 1,000 RU/s and 25 GB of storage for one account per Azure subscription, and a 30-day trial is listed. The Azure Cosmos DB emulator provides a no-cost local development environment for Windows or Linux. The pricing page notes that the selected compute pricing model and API cannot be changed after selection.
Neon
Neon is a managed, cloud-hosted PostgreSQL service for relational databases. It adjusts compute resources to workload and can suspend compute during inactivity, restarting it when database activity resumes. Database branches are isolated, can be created in about a second, and share data through copy-on-write storage. Neon supports connection pooling through PgBouncer, read replicas, high availability, point-in-time recovery, JSON data, and seven-day backup retention. An API lets teams manage projects and databases programmatically. Documented workflows include Vercel, Prisma, Drizzle ORM, GitHub Actions, and its CLI. The Free plan is free, with 10 projects, 50 CU-hours per month per project, 0.5 GB storage per project, 10 branches per project, and 5 GB monthly egress. Launch is $0.11 a month, billed at $0.106 per CU-hour; Scale is $0.22 a month, billed at $0.222 per CU-hour. Neon states that stored data is encrypted with AES-256 and data in transit uses TLS 1.2 or higher. It says it joined Databricks in May 2025 and is now part of the Databricks Platform.
