Browse Kotlin Multiplatform libraries

Operation-level Mastodon API clients with generated per-operation modules, SDK for composing operations, Gradle tasks, CLI tools, and MCP server exposing Mastodon tooling to AI assistants.

Enable @Parcelize and Parcelable usage in shared common code; build plugin auto-applies parcelize compiler, adds runtime, and generates real Parcelable implementations where supported.

Enforces explicit opt-in for global mutable state via RequiresGlobalState annotation; detects top-level and singleton mutables, offers configurable blacklist and Gradle integration.

Generate native splash screens from a single Gradle DSL, auto-producing per-density assets and launch assets; runtime API to preserve/remove splash until UI ready, with dark‑mode and per‑flavor wiring.

Decomposes Compose presenters, eliminating callback and event plumbing by generating compile-time routing between parent and child events/effects, enabling clean, callback-free fused sub-presenters.

Supports Kotlin as a target for ANTLR, offering a plugin for generating lexers, parsers, and listeners, along with a multi-platform runtime library. Experimental status.

GraphQL client library enables interaction with GraphQL servers, supporting multiple platforms. Provides a type-safe, configurable client using Ktor, with a Gradle plugin for code generation.

Monorepo encompasses multiple projects, each with distinct builds and configurations, offering features like DSL builders, Spring Boot applications, BER data encoding, and Gradle convention plugins.

Simplifies Android project development with a main function, streamlined APIs, and easy permission handling, enhancing efficiency and ease of use. Additional features and improvements planned.

Asynchronous framework for building microservices and web applications, leveraging coroutines for non-blocking I/O. Offers flexible, testable architecture with unified interception and hosting API.

Enables publishing libraries to Maven repositories, including MavenLocal and MavenCentral, with guidance on configuring developer credentials, generating GPG keys, and running sample apps on Android and iOS.

Automates internationalization by processing YAML translation files, generating platform-specific resources, and type-safe code. Offers type-safe access, streamlined team collaboration, and seamless production readiness with efficient, structured translation management.

Compile-time replacement of default function argument expressions, enabling type-safe, zero-runtime-cost retrieval for displaying defaults in CLI help, configurations, and generated documentation.

Embeds QuickJS to fetch and run JavaScript modules at runtime, enabling hot-updates, bridged interfaces with serialization, modular caching, precompiled bytecode, profiling, and signature verification.

Generates an interactive gallery of UI components from story files via a Gradle plugin, enabling isolated component development, preview app generation, and compiler/runtime integration.

Native TDLib wrapper exposing JSON-based send, receive and execute APIs, automatic native library extraction/loading, JNI and cinterop bridges, prebuilt native cache and build tooling.

Instruments classes at compile time to automatically track and visualize Compose State, Flows and function actions; adds diagram-style variable captures, optional stack traces, and pluggable loggers.

Schema compiler and runtime for protobuf: generates strongly-typed message models, handles binary encoding/decoding, offers Moshi/Gson JSON adapters, and supports Okio relocation for compatibility.

Enforces structural acyclicity in source code: compiler-plugin family detecting semantic file cycles, rejecting same-file declaration recursion, enforcing declaration order, and supporting explicit all-participant opt-out annotations.

Compile-time capture of marked source snippets via annotation, emitting runtime-accessible literal lists containing source text, location and kind, with per-marker option overrides and zero runtime cost.

Compile-safe, zero-boilerplate navigation with typed routes, arguments and results; three integration modes (annotation-based codegen, sealed-class DSL, class-based screens), shared-element transitions and back-with-result support.

Compiles AT Protocol lexicons into typed classes, generates API interfaces and HTTP (Ktor) implementations, and supplies OAuth and Jetstream bindings plus a Gradle plugin for schema generation.

Versioned shared backbone for apps: published libraries (MVI runtime, design system, image), unified build and style tooling, and Claude Code AI assets that teach assistants to adopt and use conventions.

Circuit-based, zero-allocation frontend skeleton enabling deterministic, nanosecond-tier, lock-free data pipelines via flat, preallocated arrays, compiler-enforced memory budgets, SoA ECS and native UI bindings.
