CrateDB

CrateDB is a distributed SQL database for time-series, document and search workloads. It is developed by Crate.io and licensed under Apache-2.0, an open-source licence, although the Enterprise features are separate from the Apache-2.0 core, so buyers who need them should confirm what the enterprise licence covers. It is also categorised as a multi-model NoSQL and relational database. It can be run self-managed, or as CrateDB Cloud on AWS, Azure and Google Cloud, and CrateDB Enterprise is the commercial edition. The latest release is 6.4.5, dated 16 September 2026. Cloud pricing begins with a free plan of 2 vCPU, 2 GB of RAM and 8 GB of storage. The Shared plan starts from $0.073 an hour, and the Dedicated plan starts from $0.246 an hour. The open-source database is free to run on your own infrastructure. CrateDB suits teams that want to query time-series, document and search data in one place using SQL, and that want a choice between operating the database themselves and using a managed cloud service. Its position as a time-series database rests on its fit for time-series and IoT data, and buyers should test it against their own workloads. The project shows as active.
