JayDB vs RethinkDB
Both stand on document databases. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Open source AndroidAPIiPhone+5
Choose JayDB when an app needs per-user sign-in and straightforward JSON documents, with managed hosting or a self-hosted option. Look elsewhere if the data model requires joins, indexes, search, aggregation, vector search, or atomic changes across documents.

Free plan Open source APILinuxMac+3
Choose RethinkDB for a free, open-source JSON database when applications need to subscribe to changing query results. Look elsewhere if the workload requires SQL, strong schema enforcement, full ACID support, or atomic multi-document updates.
