    ClassyShark

    ClassyShark

    Android and Java bytecode viewer

    ClassyShark is a standalone binary inspection tool for Android developers. It can reliably browse any Android executable and show important info such as class interfaces and members, dex counts and dependencies. ClassyShark supports multiple formats including libraries (.dex, .aar, .so), executables (.apk, .jar, .class) and all Android binary XMLs: AndroidManifest, resources, layouts etc. We developed this software because we needed something lighting fast and incredibly lightweight for browsing Android APKs, so that we could check right away if everything we wanted was right inside the final executable. Right after ClassyShark loads your executable, you will see, in the left panel, the list of the root components of the archive. You can activate the view by simply clicking on the Methods count tab on top of the navigation tree.

    DoKit

    DoKit

    A platform for the life cycle of pan-front-end product development

    DoKit is a debugging and quality-of-experience toolkit for mobile (primarily Android) apps that provides an in-app overlay with tools for inspection, monitoring, and interaction. It offers features like CPU/memory monitoring, frame rate detection, network logging, view hierarchy inspection, and plugin support to expand capabilities. Developers can interactively explore UI layouts, measure layout times, simulate slow networks, or trace touch events—all while the app is running on the device. DoKit aims to shorten feedback loops by surfacing internal state and metrics in situ rather than relying solely on external logging or tooling. Because it’s modular, teams can include only the subsystems relevant to their needs and disable others in production builds. The result is a rich, on-device observability layer that supports debugging performance, layout bug hunts, and UX tuning without deeply invasive instrumentation.

    Error Prone

    Error Prone

    Catch common Java mistakes as compile-time errors

    Error Prone is a static analysis tool for Java that catches common programming mistakes at compile-time. It’s common for even the best programmers to make simple mistakes. And sometimes a refactoring that seems safe can leave behind code that will never do what’s intended. We’re used to getting help from the compiler, but it doesn’t do much beyond static type checking. Using Error Prone to augment the compiler’s type analysis, you can catch more mistakes before they cost you time, or end up as bugs in production. We use Error Prone in Google’s Java build system to eliminate classes of serious bugs from entering our code, and we’ve open-sourced it, so you can too.

    KOOM creates a mobile high-performance online memory monitoring solution, which supplies a detailed report when OOM-related problems are detected and has solved a large number of OOM issues in the Kwai application. It's currently available on Android. With the increasing complexity of mobile terminal business logic and the gradual popularity of scenarios with high memory requirements such as 4K codec and AR magic watch, the OOM problem has become the number one problem in the stability management of the Kuaishou client. In the daily version iteration process, OOM surges occasionally occur, and the online environment is very complicated. There are thousands of AB experiments. Pre-prevention and post-recovery cannot be achieved. Therefore, high-performance online memory monitoring solutions are urgently needed.

    LMAX Disruptor

    LMAX Disruptor

    High performance inter-thread messaging library

    LMAX aims to be the fastest trading platform in the world. Clearly, in order to achieve this we needed to do something special to achieve very low-latency and high-throughput with our Java platform. Performance testing showed that using queues to pass data between stages of the system was introducing latency, so we focused on optimising this area. The Disruptor is the result of our research and testing. We found that cache misses at the CPU-level, and locks requiring kernel arbitration are both extremely costly, so we created a framework which has "mechanical sympathy" for the hardware it’s running on, and that’s lock-free. This is not a specialist solution, it’s not designed to work only for a financial application. The Disruptor is a general-purpose mechanism for solving a difficult problem in concurrent programming. It works in a different way to more conventional approaches, so you use it a little differently than you might be used to.

    Mixin

    Mixin

    Mixin is a trait/mixin and bytecode weaving framework for Java

    Mixin is a trait/mixin framework for Java using ASM and hooking into the runtime classloading process via a set of pluggable built-in or user-provided services. Built-in services currently support Mojang's LegacyLauncher system, though this is deprecated in favor of ModLauncher by cpw, which has greater extensibility and has support for Java 8 and later. Additional documentation for individual features and annotations can be found in the extensive Javadoc. For additional help use the channel #mixin on the Sponge Discord Server. For handling obfuscation tasks, Mixin provides an Annotation Processor which works at compile time to generate obfuscation mappings for your toolchain to apply. If using Gradle 5 or later, annotation processors are no longer automatically loaded from compile configurations and must be specified explicitly via annotationProcessor configurations.

    Mosby

    Mosby

    Model-view-presenter and model-view-intent library for modern Android

    Mosby is a model-view-presenter and model-view-intent library designed specifically for Android apps. Migrating a Mosby 2.x based app to Mosby 3.0 should be straightforward. Just replace all import statements of your app in android studio. Mosby has a plugin for Conductor. The aim of this library is to help you build modern android apps with a clean Model-View-Presenter architecture. Furthermore, Mosby helps you to handle screen orientation changes by introducing ViewState and retaining Presenters. At first glance Mosby looks a lot like a framework. There are some classes like MvpFragment you can extends from, but the point is that you don’t have to if you don’t want to. At it’s core Mosby is a tiny library based on delegation. So you don’t have to use MvpFragment if you don’t want to. You can use delegation and composition to integrate Mosby in your own development stack. Hence you are not caught into a frameworks boundaries and limits.

    Netty

    Netty

    An event-driven asynchronous network application framework

    Netty is an asynchronous, event-driven networking framework for the JVM that simplifies building high-performance clients and servers. It wraps Java NIO with a channel/handler pipeline model, enabling clean composition of codecs, TLS, and application logic with minimal overhead. Its ByteBuf abstractions, buffer pooling, and zero-copy techniques help reduce GC pressure and improve throughput under heavy I/O. Support for common protocols—HTTP/1.1, HTTP/2, WebSocket, and raw TCP/UDP—makes it a foundation for RPC frameworks, proxies, and messaging systems. Pluggable transports and native integrations (like epoll or kqueue where available) allow fine-tuning for different operating systems. With robust resource management, leak detection, and extensive testing, Netty is widely chosen when low latency, scalability, and control over the I/O stack are required.

    OpenAPI Generator

    OpenAPI Generator

    OpenAPI Generator allows generation of API client libraries

    With 50+ client generators, you can easily generate code to interact with any server which exposes an OpenAPI document. Maintainers of APIs may also automatically generate and distribute clients as part of official SDKs. Each client supports different options and features, but all templates can be replaced with your own Mustache-based templates. Getting started with server development can be tough, especially if you're evaluating technologies. We can reduce the burden when you bring your own OpenAPI document. Some generators support Inversion of Control, allowing you to iterate on design via your OpenAPI document without worrying about blowing away your entire domain layer when you regenerate code. Ever wanted to iteratively design a MySQL database, but writing table declarations was too tedious? OpenAPI documents allow you to convert the metadata about your API into some other format.
