Native file picker

Flutter File Picker is a cross-platform file selection library that integrates native operating system dialogs into applications. It allows users to pick single or multiple files from device storage or connected cloud services, select directories, and open save-as dialogs to export data. The library handles file operations by invoking host platform system dialogs directly without custom UI rendering. It supports filtering selectable files through preset media categories or custom file extensions, loading file bytes directly into memory as raw data, and streaming large files through increment

react-dropzone is a reusable React UI component for implementing HTML5 drag-and-drop file transfers. It provides a React file upload component that manages file selection and drop zone states within a web application. The project enables the creation of interactive file upload interfaces where users can drag files from their local system or select them via a file browser. It integrates with the native system file picker dialog and supports the File System Access API.

QuickLook is a utility for the Windows operating system that provides instant file previews through keyboard shortcuts. It allows users to inspect the contents of documents, media, and code without the need to launch the associated software applications. The application integrates directly into the system file manager and open dialog windows, ensuring a consistent preview experience across the operating system. It utilizes a modular plugin architecture that enables the rendering of diverse file formats, including office documents, engineering drawings, and vector graphics, without requiring t

pywebview is a cross-platform desktop GUI framework for Python that renders HTML, CSS, and JavaScript content using the operating system's native web rendering engine. It enables developers to build desktop applications that run on Windows, macOS, and Linux from a single Python codebase, with the web frontend displayed in a lightweight, native window. The framework provides a bidirectional JavaScript-Python bridge for real-time data exchange between frontend and backend, along with the ability to manipulate the Document Object Model directly from Python without writing JavaScript. It includes

material-dialogs is a Kotlin UI component library that provides a collection of modal dialogs and bottom sheets for Android applications. It is designed to implement user interface elements that follow Material Design standards. The library provides specialized modal interfaces for selecting calendar dates, clock times, and specific color values. It also includes system chooser integrations for selecting files and directories from local storage. Beyond pickers, the library covers a broader range of interaction components including text input dialogs, modal alerts with action buttons, and bot

Vuido is a framework for building native desktop applications for Windows, macOS, and Linux using Vue.js components, without requiring Electron or Chromium. It maps Vue components directly to native widgets from the libui library, creating lightweight applications that run on a single-threaded event loop and compile templates at build time for optimized runtime performance. The framework provides a complete Vue.js component-to-native bridge, enabling two-way data binding via v-model, component-based window composition, and platform-specific package generation for distributing executables. It

FlatLaf is a Java Swing look and feel library and theme engine that provides a modern flat design for desktop user interfaces. It serves as a comprehensive framework for applying visual themes, managing high-density scaling, and implementing customized window decorations. The project distinguishes itself through a flexible styling system that supports light and dark mode toggling and the ability to define visual identities via property files, subclassing, and external theme imports. It includes a dedicated scaling framework to ensure that interface elements and vector icons remain crisp on Hi

This project is a cross-platform UI framework and native desktop GUI library. It provides a unified set of instructions to render native windows, forms, and layouts across different operating systems by mapping high-level instructions to the native widgets and controls of the host environment. The toolkit includes a vector graphics engine for rendering custom shapes, gradients, and high-density images using brushes and matrices. It also serves as a native dialog provider for system-level operations such as file path selection and message box alerts. The library covers a broad range of GUI co

Anko is an Android Kotlin library designed to simplify application development through a set of domain-specific languages and extensions. It functions as a programmatic UI DSL, an SQLite wrapper, an SDK utility, and an asynchronous framework. The project provides a declarative layout system that allows developers to build user interfaces through code instead of static XML markup. It distinguishes itself by offering a fluent database layer that eliminates manual cursor management and a concurrency system that uses weak references to prevent memory leaks in activities. The library covers broad

Terminal.Gui is a cross-platform .NET toolkit for building interactive text-based user interfaces. It provides a component-based architecture, a terminal rendering engine, and a declarative layout system to create console applications that run consistently across Windows, macOS, and Linux. The framework distinguishes itself with a comprehensive set of interactive console widgets, including data grids, hex editors, and hierarchical tree components. It supports advanced visual capabilities such as 24-bit True Color, Sixel image support, and a relative-coordinate layout system that adapts to ter

Fyne is a cross-platform graphical user interface toolkit for the Go programming language. It provides a comprehensive framework for building native applications that run on desktop, mobile, and web environments from a single codebase. The toolkit centers on a canvas-based rendering engine and a device-independent layout engine, ensuring that visual elements maintain consistent dimensions and behavior across diverse operating systems and screen densities. The project distinguishes itself through a reactive data-binding system that automatically synchronizes application state with interface co

Druid is a native user interface toolkit and 2D graphics engine for the Rust programming language. It functions as a retained-mode, data-driven framework for building graphical user interfaces that run across Linux, macOS, and web browsers via WebAssembly. The toolkit distinguishes itself through a data-first approach to UI design, utilizing lenses to isolate subsets of global application state and synchronize them with specific widgets. This allows the visual layout to update automatically when the underlying data model changes. Its capability surface includes a constraint-based box layout
