Top 6 Kotlin ORM Projects

ORM

  1. Exposed

    Kotlin SQL Framework

    Project mention: Three Stabs at a Typed Schema DSL in Kotlin | dev.to | 2026-05-12

    Declaring keys by hand is clunky: you'd be tracking them yourself for the StatGroup, and writing each name twice (once on the property, once as a string). Kumulant uses property delegates on a singleton object instead. Same pattern as JetBrains' Exposed, minus the duplicate name.

  2. SaaSHub

    A blazing fast, powerful, and very simple ORM android database library that writes database code for you.

  4. Ktorm

    A lightweight ORM framework for Kotlin with strong-typed SQL DSL and sequence APIs.

  5. RoomAsset

    A helper library to help using Room with existing pre-populated database [DEPRECATED].

  6. kimmer

    1. Immer. 2. SQL DSL

  7. jds

    Jenesis Data Store: a dynamic, cross platform, high performance, ORM data-mapper. Designed to assist in rapid development and data mining
