Hi @loke Exposed is built on top of Java database connectivity (JDBC) API and requires such a driver for database access, so multiplatform support isn't currently available.
At the moment, the major feature being worked on is refactoring the codebase to support reactive drivers (R2DBC). Once that is implemented in the stable release, much of the refactoring involved will bring Exposed even closer to working with multiplatform and the feature can be properly addressed.
