ShareX is a comprehensive screenshot, image editing, and file sharing application for Windows. It features a modular architecture with separate libraries for screen capture, image editing, uploading, helpers, history, and tools. The application supports capturing screenshots/recordings, applying annotations and effects, uploading to over 50 services, and includes various productivity tools. Built with .NET/C# using a mix of Windows Forms and Avalonia UI frameworks, it employs MVVM patterns, plugin architectures for extensibility, and cross-cutting helper libraries. The system handles data flows from capture through editing to upload/storage, with history tracking for user convenience.
LinkSheet is an Android application that intercepts URL intents and presents a Material3 bottom sheet allowing users to choose which app or browser handles the link. In production, it replaces the removed Android 12+ chooser, supporting preferred app per domain, usage-based sorting, browser modes (always ask, none, whitelisted, single browser), and advanced URL processing including AMP to HTML conversion, redirect following, ClearURLs (tracker removal), FastForward (redirect bypass), LibRedirect (privacy-friendly frontends), and a custom rule engine (scenarios) for fine-grained link routing. The architecture is multi-modular: core app module, feature modules (analytics, backup, browser, device compat, downloader, engine, libredirect, profile, remote config, shizuku, wiki), integration libraries (amp2html, clearurl, embed-resolve, fastforward, mime-types), and shared libraries (api, compose, bottom-sheet, scaffold, http). Key entry points are `BottomSheetActivity`, `MainActivity`, and `LinkEngineService`. The system uses Koin dependency injection, Jetpack Compose for UI, Room for local caching, Ktor/OkHttp for networking, and Shizuku for privileged operations. It is actively maintained with nightly builds, extensive unit/instrumentation tests, and a large localization effort across 20+ languages.
