Best Multimodel Databases in 2026
If your applications work with different kinds of data, compare which models each database supports and how you can query them. Graph querying, SQL support, and vector search offer distinct capabilities to weigh against your application’s needs. Deployment options and multi-region support can help you assess operational fit, while free-plan availability and paid-from pricing provide cost context. Amazon DynamoDB, RavenDB, and ArcadeDB are among the options, alongside CrateDB and InterSystems IRIS. Consider the data structures and query methods your applications require, then compare the listed deployment and support details with your intended environment.
