Universal Android Debloater

Cross-platform GUI written in Rust using ADB

Universal Android Debloater is a command-line tool and GUI wrapper for managing and removing unwanted system apps and bloatware from Android devices—especially rooted ones. It reads a set of “profiles” corresponding to different manufacturers or Android versions, listing packages recommended for removal or disabling while preserving system stability. The tool communicates with the device over ADB (Android Debug Bridge), uninstalls or disables packages, and can restore disabled apps in case something breaks. Because removing critical system apps can break functionality, the tool emphasizes safety: it often suggests backups, lists dependencies, and allows dry runs before executing. For power users and tinkerers, it provides a curated, convenient way to slim down Android installations without manually running dozens of pm uninstall commands.

It's a community-driven fork of AltStore, and has already implemented some of the community's most-requested features. SideStore is a just regular, sandboxed iOS application. The AltStore app target contains the vast majority of SideStore's functionality, including all the logic for downloading and updating apps through SideStore.

PHP Desktop

Develop desktop GUI applications using PHP, HTML5, JavaScript

PHP Desktop is an open-source project founded by Czarek Tomczak in 2012 to provide a way for developing native desktop GUI applications using web technologies such as PHP, HTML5, JavaScript and SQLite. Think of it as Electron for PHP. It is a convenient tool for converting PHP web apps and PHP CLI tools to desktop applications with little effort. The development workflow you are used to while creating web applications remains the same, there is no new framework / API to learn. The process of turning an existing website into a desktop application is basically a matter of copying it to the directory. In a certain sense phpdesktop acts as a PHP to EXE compiler. It embeds a web browser, a multi-threaded web server and a PHP interpreter. All embedded into a single application, a portable folder that you can easily distribute to end-users by packing it to zip archive or by making an installer for your application. The web server embedded is a custom edition of Mongoose.

Tailwind CSS

A utility-first CSS framework for rapid UI development

Rapidly build modern websites without ever leaving your HTML. A utility-first CSS framework packed with classes like flex, pt-4, text-center and rotate-90 that can be composed to build any design, directly in your markup. Utility classes help you work within the constraints of a system instead of littering your stylesheets with arbitrary values. They make it easy to be consistent with color choices, spacing, typography, shadows, and everything else that makes up a well-engineered design system. Because Tailwind is so low-level, it never encourages you to design the same site twice. Even with the same color palette and sizing scale, it's easy to build the same component with a completely different look in the next project. Tailwind automatically removes all unused CSS when building for production, which means your final CSS bundle is the smallest it could possibly be. In fact, most Tailwind projects ship less than 10kB of CSS to the client.
