Kotlin Multiplatform Mobile (KMM) is an SDK designed to simplify creating cross-platform mobile applications. With the
help of KMM, you can share common code between iOS and Android apps and write platform-specific code only where it’s
necessary. For example, to implement a native UI or when working with platform-specific APIs.
Kotlin/Native provides integration with the CocoaPods dependency manager. You can add dependencies on Pod libraries as well as use a multiplatform project with native targets as a CocoaPods dependency (Kotlin Pod).
Plugin to facilitate debugging iOS applications using Kotlin Native in Xcode. Defines Kotlin files as source code, with basic highlighting. Allows you to set breakpoints and includes llvm support to view data in the debug window. Xcode does not officially support custom language definitions, but they also don't explicitly block them.
Dokka is a documentation engine for Kotlin, performing the same function as javadoc for Java. Just like Kotlin itself, Dokka fully supports mixed-language Java/Kotlin projects. It understands standard Javadoc comments in Java files and KDoc comments in Kotlin files, and can generate documentation in multiple formats including standard Javadoc, HTML and Markdown.
Napier is a logger library for Kotlin Multiplatform. It supports for the Android, Darwin(iOS, macOS, watchOS, tvOS), JVM, JavaScript. Logs written in common module are displayed on logger viewer of each platform.
Kermit is a Kotlin Multiplatform logging utility with composable log outputs. The library provides prebuilt loggers for outputting to platform logging tools such as Logcat and NSLog.
Kodein-Log is a lightweight Kotlin/Multiplatform logging library with a simple API, that works on JVM, Android, JavaScript, iOS, as well as for all Kotlin/Native targets.
Klogger is a logger library for multiplatform Kotlin. This library provides a simple interface to do logging into suitable outputs like javascript’s console, or stdout/stderr.
Ktor includes a multiplatform asynchronous HTTP client, which allows you to make requests and handle responses, extend its functionality with plugins (formerly known as features), such as authentication, JSON serialization, and so on.
SQLDelight generates typesafe kotlin APIs from your SQL statements. It verifies your schema, statements, and migrations at compile-time and provides IDE features like autocomplete and refactoring which make writing and maintaining SQL simple.

Summer - Share ViewModels between iOS, Android and Web apps
Summer is a presentation level library with kotlin-multiplatform support. It can be used to share viewModels between iOS, Android and Web apps. Summer does not use code generation and thus have not significant effort on compilation time and odd build-time errors. Project aims to have out-of-box support of Android Framework, Jetpack Compose, UIKit and SwiftUI without any adapters and platform-specific limitations.
Premo — Presentation Model (aka View Model) and Navigation
Premo is a Kotlin Multiplatform library that helps to implement the Presentation Layer and share it on iOS, Android, Desktop and Web. Focus on writing logic instead of solving common and boring UI related issues: lifecycle, persistence, navigation, etc.
Decompose is a Kotlin Multiplatform library for breaking down your code into lifecycle-aware business logic components (aka BLoC), with routing functionality and pluggable UI (Jetpack Compose, Android Views, SwiftUI, JS React, etc.)
Kotlin Multiplatform snapshot ((c|k)lip) manager for tests. Automatically generates and asserts against a persistent Any::toString() representation of the object until you explicitly trigger an update. Powered by kotlin compiler plugin to inject relevant keys and paths.
🔑 Crypto
Libsodium - Libsodium bindings for Kotlin Multiplatform
Libsodium bindings project uses libsodium c sources and libsodium.js to provide a kotlin multiplatform wrapper library for libsodium.
Kotlin Multiplatform (KMP) library for MurmurHash, a non-cryptographic hash function for general hash-based lookup focused on simplicity and performance.
Kotlin multiplatform file system i/o for android, iOS, Java and NodeJS
🚀 Language extentions
Arrow - Functional companion to Kotlin's Standard Library
Arrow aims to provide a lingua franca of interfaces and abstractions across Kotlin libraries. For this, it includes the most popular data types such as Option, Either, Validated etc and functional operators such as traverse and computation blocks to empower users to write pure FP apps and libraries built atop higher order abstractions.
Kotlin serialization consists of a compiler plugin, that generates visitor code for serializable classes, runtime library with core serialization API and support libraries with various serialization formats.
Klock is a Date & Time library for Multiplatform Kotlin. It is designed to be as allocation-free as possible using Kotlin inline classes, to be consistent and portable across targets since all the code is written in Common Kotlin, and to provide an API that is powerful, fun and easy to use.
The Firebase Kotlin SDK is a Kotlin-first SDK for Firebase. It's API is similar to the Firebase Android SDK Kotlin Extensions but also supports multiplatform projects, enabling you to use Firebase directly from your common source targeting iOS, Android or JS.
This library gives access to TMDb API version 3 and 4 for mobile, desktop, and web applications. It supports Swift, Kotlin, and JavaScript by setting up as a Kotlin Multiplatform project.
GrowthBook is an open-source platform for feature flagging and a/b testing built for data teams, engineers, and product managers. It's great whether you're looking to just analyze experiment results or looking to make it easier to deploy code.
Kotlin Multiplatform BigNum library is a pure kotlin implementation of arbitrary precision arithmetic operations. It follows the same approach as Kotlin does on JVM to keep the interface familiar.
Kotlin Multiplatform (KMP) plugin and library that add support for reading resources in tests.
The plugin and a library work in tandem to provide a unified API across platforms for reading resources from each source set's resources folder.
