Eureka is a framework for building structured data-entry interfaces and forms in Swift for iOS applications. It provides a declarative UI layout engine and a dynamic input interface to define fields, sections, and row layouts through a configuration layer. The system distinguishes itself through dynamic interface management, including conditional visibility and interaction control that reacts to real-time user changes. It supports complex input behaviors such as expandable row rendering, multivalued field management for inserting or deleting similar rows, and custom keyboard navigation that s

cardslib is an Android UI component library and card layout framework. It provides a set of specialized adapters and views designed as an extension for high-performance card rendering within recycling lists. The library distinguishes itself through a reorderable list implementation that supports drag-and-drop item rearrangement and nested content hierarchies. It also includes an interaction system for managing directional swipe constraints and a customizable undo action notification bar. The framework covers a broad range of card-based interface capabilities, including the composition of vis

Litho is an Android declarative UI framework and component library used to build user interfaces through a declarative API and immutable state. It functions as an asynchronous layout engine that maps components to a structured view hierarchy to automate view updates. The framework optimizes rendering performance by computing element positions on background threads to prevent blocking the main UI thread. It further improves efficiency by flattening nested view hierarchies and caching layout results. The system includes capabilities for state reconciliation, component recycling, and the render

TapTargetView is a set of UI components designed for user onboarding and feature discovery. It provides visual callouts, focus indicators, and markers that direct user attention toward specific screen elements to introduce new or hidden functionality. The system implements Material Design guidelines for its feature discovery UI, ensuring that visual highlights and interactive callouts remain consistent with standardized design specifications. It supports the creation of interactive product tours by chaining multiple interaction points into a sequential path. This is achieved through coordina

nprogress is a lightweight JavaScript UI component and web progress bar library. It provides a minimalist DOM progress indicator used to track the state of asynchronous operations within a browser document. The library allows for the visualization of loading states through a thin progress bar and spinner. It supports progress state management, enabling the bar to be started, stopped, or marked as complete, with support for incremental progress tracking and percentage-based updates. Users can modify the visual style by overriding default CSS or replacing the markup template. The component als

ComponentKit is a declarative UI framework for building iOS interfaces through composition of small, reusable components. It provides a structured approach to constructing user interfaces where each component is defined as an immutable, pure function of its inputs, enabling predictable rendering and state management. The framework supports both stateless and stateful components, with controllers that can be attached to manage persistent state across component updates. The framework distinguishes itself through its component architecture that emphasizes explicit data flow and compile-time safe

Paper.js is an HTML5 Canvas vector graphics library and scripting framework used for creating and manipulating 2D shapes and paths. It functions as a vector animation framework and a headless vector graphics engine, allowing for the execution of graphics operations in both browser and server-side environments. The project features a dedicated SVG import and export engine to convert between native vector items and the SVG format. It includes a specialized boolean path operation toolkit for uniting, subtracting, and intersecting vector paths to create complex geometric shapes. The library cove

Background Removal JS is a client-side neural matting library that runs a lightweight AI model directly in the browser to compute alpha mattes, removing image backgrounds without uploading any data to a server. It functions as a browser-based image background removal SDK and client-side image matting library, keeping all processing on the user's device to eliminate server costs and preserve privacy. The project provides a cross-platform creative editing engine that produces identical image and video output across web, mobile, desktop, and server environments from a single codebase. It offers
