Open Source Kotlin Database Software

Welcome to Exposed, an ORM framework for Kotlin. Exposed offers two levels of database access: typesafe SQL wrapping DSL and lightweight data access objects. Our official mascot is Cuttlefish, which is best known for its outstanding mimicry abilities letting it blend seamlessly in any environment. Just like our mascot, Exposed can mimic a variety of database engines and help you build database applications without hard dependencies on any specific database engine, and switch between them with very little or no changes in your code. Exposed is currently available for maven/gradle builds at Maven Central.

DBFlow is fast, efficient, and feature-rich Kotlin database library built on SQLite for Android. DBFlow utilizes annotation processing to generate SQLite boilerplate for you and provides a powerful SQLite query language that makes using SQLite a joy. DBFlow is built from a collection of some of the best features of many database libraries. Don't let an ORM or library get in your way, let the code you write in your applications be the best as possible. Built using the language, the library is super-concise, null-safe and efficient. Generates the necessary code that you don't need to write. Contains the main annotations and misc classes that are shared across all of DBFlow. The main library artifact used in conjunction with the previous two artifacts. Adds coroutine support for queries. Enable applications to be reactive by listening to DB changes and ensuring your subscribers are up-to-date.

Android library for viewing, editing and sharing in-app databases. DbInspector provides a simple way to view the contents of the in-app database for debugging purposes. There is no need to pull the database from a connected device. This library supports inspecting of the SQLite databases created by CouchBase Lite out of the box. Preview all application sandbox databases. Import single or multiple databases at once. Search, delete, rename, copy, share a database. Preview tables, views, and triggers. Preview table or view pragma. Preview table or view pragma. Search table, view or trigger. Sort table, view or trigger per column. Execute any valid SQL command in editor per database connection. If you use DbInspector for a specific flavor and need to override merged in launcher label, you can provide a String resource in your project. DbInspector has a build in editor scoped per database connection currently used.
