Pick JayDB if…
JayDB may suit developers building static or AI-built apps that need per-user, session, or tenant data, including shared documents across users or workers. It is a limited fit for applications that require relational features, full-text search, or multi-document atomic writes.
Pick UnQLite if…
UnQLite suits developers who need an embedded database with key/value or JSON document storage and no separate server. Its self-contained library is intended for embedded devices and applications running across varied computer configurations.
