Facilitates sharing UIs across iOS, Android, Desktop, and Web using a declarative framework. Provides high-performance UI rendering, native APIs access, and desktop-specific extensions. Includes libraries for web UI creation.

Create asynchronous client and server applications. Anything from microservices to multiplatform HTTP client apps in a simple way. Open Source, free, and fun!

Enables asynchronous programming with lightweight coroutines, offering structured concurrency, cancellation, and integration with various reactive streams and UI frameworks. Includes testing and debugging utilities.

Image loading library optimized for Android apps, featuring memory and disk caching, minimal boilerplate, and integration with modern libraries. Supports ImageView and Jetpack Compose with customizable requests.

Pragmatic lightweight dependency injection framework using a DSL and light container. Offers packages for core, coroutines, testing, Android, Ktor, annotations, and Jetpack Compose integration. Includes tutorials and community support.

Simplifies accessing, storing, and processing data by enhancing `java.io` and `java.nio` capabilities. Originated from OkHttp, ensuring robust performance for various data handling needs.

Generates typesafe APIs from SQL statements, verifies schema and migrations at compile-time, and enhances IDE with autocomplete and refactoring for simplified SQL management. Supports multiple SQL dialects.

Provides typed functional programming interfaces and abstractions, including popular data types like `Option` and `Either`, functional operators, and computation blocks to support pure functional programming.

Exposes metadata to help tools and developers understand code, offering common API annotations (including Java-compatible OptIn) and dependency artifacts for easy integration.

Reduces memory footprint of small collections with memory-optimized list, map, and set implementations—drop-in replacements minimizing allocations and overhead while preserving familiar collection APIs and behavior.

Declarative UI toolkit enabling programmatic UI via composable functions, offering animations, Material (including Material 3), foundation building blocks, compiler optimizations, runtime state management, and core UI primitives.

Asynchronous, consistent, transactional storage replacing SharedPreferences; supports preferences and typed objects with Proto/JSON serialization, optional Rx adapters, and atomic updates.

This is androidx library, that was not documented or supported well. It is probably just a KMP module, that could be used on your own responsibility.

Responding to component state changes: ViewModel and LiveData APIs, Compose integrations, saved-state handling, process-wide state tracking, ReactiveStreams support, and testing utilities.

Simplifies navigation between UI destinations via a consistent API, offers type-safe arguments (Safe Args), Compose and fragment integrations, feature-module support, and testing utilities.

Declarative navigation for Compose UIs, offering runtime and UI modules, navigation graphs, deep-linking, lifecycle-aware back stack handling, and simplified dependency setup.

Unified API for system Back and Predictive Back events, simplifying back navigation and predictive gesture support across app components and lifecycles.

Gracefully load and display large datasets in RecyclerViews via incremental paging, with support for RxJava, Guava ListenableFutures, testing variants, and Jetpack Compose integration.

Enables pluggable components that save UI state across process death and restore it on restart, offering simple dependency setup and a concise API for state persistence.

Abstract SQLite interfaces with basic implementations, plus framework bindings and language-friendly extensions to build customized database access layers; intended as a lightweight alternative to higher-level ORMs.

Enables reflectionless serialization for classes by generating visitor code through a compiler plugin, and includes a runtime library supporting various formats like JSON, Protobuf, CBOR, Hocon, and Properties.

Highly customizable calendar library supporting single, multiple, and range date selection modes. Features include horizontal/vertical scrolling, heatmap calendar, custom views, and flexible date boundaries.

Single-executable open backend delivering sub-millisecond REST and realtime APIs, multi-database support, WASM runtime for extensibility, geospatial queries, SSR, built-in auth and admin UI.

Flexible and comprehensive testing tool offering a variety of testing styles, assertions, and integrations for seamless test creation and management. Includes extensive community support and resources for quick onboarding.

Manages and processes Protocol Buffers schemas, facilitating efficient schema handling and API documentation.

Framework designed for building AI agents with tool interaction, complex workflows, semantic search, and persistent memory. Offers modular architecture, real-time processing, and comprehensive tracing.

Compiles dependency details and licenses at build time, offering APIs for easy visualization in apps. Features caching, comprehensive Gradle support, custom UI builds, compliance reports, and strict license mode.

API for generating `.kt` source files, streamlining the creation of Kotlin code programmatically. Facilitates clean, efficient code generation with a focus on ease of use and flexibility.
