Shoutem UI
Customizable set of components for React Native applications
Shoutem UI is a set of styleable components that enables you to build beautiful React Native applications for iOS and Android. All of our components are built to be both composable and customizable. Each component has a predefined style that is compatible with the rest of the Shoutem UI, which makes it possible to build complex components that look great without the need to manually define complex styles. You can also use standard React Native components in your layouts anywhere you want, but they will not inherit either the theme or the parent styles, so you will need to style them manually. Shoutem UI is a part of the Shoutem UI Toolkit that enables you to build professional-looking React Native apps with ease. -

Sizzle
A sizzlin' hot selector engine
A pure-JavaScript CSS selector engine designed to be easily dropped in to a host library. Browser support may differ between standalone Sizzle and libraries that include Sizzle. Please report issues on Sizzle's issue tracker, rather than the trackers for disparate libraries. In order to build Sizzle, you should have Node.js/npm latest and git 1.7 or later (earlier versions might work OK, but are not tested). For Windows you have to download and install git and Node.js. Mac OS users should install Homebrew. Once Homebrew is installed, run brew install git to install git, and brew install node to install Node.js. Linux/BSD users should use their appropriate package managers to install git and Node.js, or build from source if you swing that way. Workarounds for Internet Explorer 6 are still in the code but the browser is no longer actively tested. Sizzle supports virtually all CSS 3 Selectors, including escaped selectors (.foo\+bar), Unicode selectors, and more. -

Stepper-Touch
Stepper Touch for Android based on MaterialUp submission
Stepper Touch for Android is based on a Material Up showcase designed by Oleg Frolov. In the latest version of the support library (25.3.0) a new class SpringAnimation was made available.

Stetho
Debug bridge for Android applications
Stetho is a sophisticated debug bridge for Android applications. When enabled, developers have access to the Chrome Developer Tools feature natively part of the Chrome desktop browser. Developers can also choose to enable the optional dumpapp tool which offers a powerful command-line interface to application internals. Alternatively you can include Stetho from Maven Central via Gradle or Maven. Only the main stetho dependency is strictly required, however you may also wish to use one of the network helpers. The integration with the Chrome DevTools frontend is implemented using a client/server protocol which the Stetho software provides for your application. Once your application is integrated, simply navigate to chrome://inspect and click “Inspect” to get started! Network inspection is possible with the full spectrum of Chrome Developer Tools features, including image preview, JSON response helpers, and even exporting traces to the HAR format. -

The Agency
A complete AI agency at your fingertips
Agency Agents is an open-source collection of specialized AI agent personas designed to function like a complete virtual agency spanning engineering, design, marketing, product, project management, testing, support, spatial computing, and other specialized roles. Rather than providing generic prompts, the project organizes each agent as a structured expert profile with personality traits, mission, workflow, deliverables, examples, and success metrics so that each one feels more like a reusable operational role than a one-off instruction. The repository is built for people who want role-based AI collaboration, whether that means using the agents directly inside Claude Code, adapting them as references, or converting them for use in other agentic tools such as Cursor, Aider, Windsurf, Gemini CLI, and OpenCode. -

XLPagerTabStrip
Android PagerTabStrip for iOS
XLPagerTabStrip is a Container View Controller that allows us to switch easily among a collection of view controllers. Pan gesture can be used to move on to next or previous view controller. It shows a interactive indicator of the current, previous, next child view controllers. The library provides 4 different ways to show the view controllers. This is likely the most common pager type. It's used by many well-known apps such as instagram, youtube, skype, and many others. The bar mode doesn't show a title neither an image. It only shows a bar that indicates the current view controller. The segmented mode uses a UISegmentedControl to indicate which view controller is being displayed. Basically, we just need to provide the list of child view controllers to show, and these view controllers should provide the information (title or image) that will be shown in the associated indicator. -

YunX
An Android network disk analysis and download app
YunX is an Android app for parsing shared cloud-drive links, browsing their contents, and downloading files directly. It recognizes links from services including Quark, UC, Xunlei, Baidu Netdisk, 139 Cloud, and 123 Cloud, and can automatically match extraction codes. Downloads use concurrent ranged chunks with resume support, persistent request headers, and a fixed chunk plan. The app can clean up temporary transferred files after obtaining direct links or after download tasks are removed. Authentication methods vary by provider and include WebView cookies, password or SMS login, and JWT-based sessions. Credentials and download tasks are stored locally, with exported authentication backups protected through password-derived AES-GCM encryption. -

fastdex
Speed up the compilation speed of apk
If you can't stand the slow compilation of apk (especially if there are multiple dex in the project), fastdex can help you speed up the apk generation process. Scan all project codes and add a dependency on the fastdex.runtime.antilazyload.AntilazyLoad class in the construction method. The purpose of this is to solve the problem of class verification. For details, please refer to Android. Take a snapshot of all the dependencies of the current project, in order to compare whether the dependencies have changed when the patch is packaged in the future. If there is a change, the cache needs to be cleared. It is strongly recommended that your application do not directly depend on the library project, but make it into an aar package so that the application project can rely on it remotely. -

haoel.github.io
Comprehensive guide on self-hosting proxies, VPNs and transparent gate
This repository is a hands-on, longform guide for building and operating your own “scientific” Internet access setup — i.e., self-hosted proxies, VPNs, and transparent gateways — so you can reach blocked resources, protect privacy, and learn the underlying networking principles. It walks through buying and evaluating VPSes (regions, bandwidth, CN2/GIA lines), enabling kernel/network optimizations (BBR), and applying production practices like TLS certificates with Let’s Encrypt and using Cloudflare safely. The guide provides multiple deployment patterns (Dockerized gost / Shadowsocks / L2TP-IPSec, IKEv2 suggestions, and Cloudflare WARP integration), plus client configuration instructions for desktop and mobile (Clash, SwitchyOmega, Shadowrocket, etc.). Several transparent gateway patterns are explained: router/OpenWRT (Clash on the router), Raspberry Pi gateway, and a data-center NAT/EC2 NAT instance design with Clash for whole-VPC routing.
