Open-source alternatives to Android Stackblur

A realtime blurring overlay for Android (like iOS UIVisualEffectView)

Dali is an image blur library for Android. It contains several modules for static blurring, live blurring and animations.

Blurry is an Android UI visual effect library used to apply Gaussian blur and color filters to mobile user interfaces. It provides a toolset for generating blurred bitmap images from source files or memory and applying these effects to Android views and layout containers. The library implements frosted glass effects by capturing static bitmap representations of UI components and rendering them as stylized overlays. This process includes radius-driven sampling to control blur intensity and color-filter integration to modify the visual mood or readability of the background. The project covers

Parallax everywhere is a library with alternative android widgets with parallax effects.

Typed.js is a JavaScript typing animation library and DOM text animator used to simulate a user typing and erasing text. It serves as a frontend animation tool for creating dynamic text transitions and visual effects within HTML elements. The library distinguishes itself through the ability to render animated typing sequences directly inside the placeholder attribute of HTML input fields. It also supports reading animation strings from static HTML elements to maintain search engine visibility and accessibility. The tool covers animation control with configurable timing and playback state man

Lottie-android is a native vector animation engine and library for Android that parses JSON specification files into high-fidelity animations. It functions as a JSON animation parser and renderer, translating After Effects exported data into native draw calls to maintain design fidelity on mobile devices. The library supports dynamic user interface control by allowing the modification of animation properties, such as colors, text, and shape attributes, during runtime playback. It also integrates with system-level accessibility settings to adjust playback and visibility in accordance with redu

Blotter is a WebGL text rendering engine and fragment shader text visualizer. It provides a system for composing and previewing stylized text effects by applying custom GLSL fragment shaders to text elements on a web canvas. The project includes a shader editor for defining and updating custom shader logic and uniforms in real time. This interface allows for the creation of unique visual styles and the modification of rendering variables without reloading the underlying logic. The engine incorporates performance optimizations for WebGL rendering, utilizing texture atlas batching and a single

Hover is a collection of pre-defined CSS3 animations and reusable stylesheets for links, buttons, and images. It serves as a web UI animation kit and a library of styles written in CSS, Sass, and LESS to provide visual feedback when a user hovers over an element. The library includes specialized interactive effects that simulate tactile behaviors, such as page curls and the rendering of speech bubbles. It also provides a set of animation primitives to manipulate backgrounds, borders, shadows, and glow effects to simulate depth and elevation. The project covers a wide range of element motion

Cocos2d-x is a high-performance C++ game development framework designed for building and deploying interactive applications across mobile, desktop, and web platforms. It functions as a cross-platform game engine that utilizes an entity-component system to manage object lifecycles, behaviors, and spatial relationships within a unified codebase. The engine is distinguished by its specialized 2D graphics rendering pipeline, which is optimized for hardware-accelerated performance when displaying sprites, particle effects, and skeletal animations. It provides developers with low-level access to gr

Transitions Everywhere is an Android view animation library and UI transition framework. It serves as an extension to the Jetpack Transitions library, providing a toolkit for implementing motion and recoloring animations during element transitions. The library enables the creation of custom scale, translation, and rotation effects to manage visual state changes in mobile interfaces. It provides a set of additional animation effects built on top of the Android Jetpack framework to achieve a dynamic visual experience. The framework covers view transition customization and UI motion design, uti

DEPRECATED Easily have blurred and transparent background effect on your Android views.

Rebound is a Java motion framework and physics engine designed to create natural physical movement in user interface animations. It functions as a spring physics library that models forces and oscillations to drive fluid interface transitions. The framework implements interactive motion design by simulating real-world spring dynamics and physical forces rather than using linear transitions. This allows for the creation of organic motion within Java applications. The engine handles physics-based animation through spring-based simulations, employing discrete time-step integration and frame-ind

FLAnimatedImage is a high-performance rendering engine and library for playing animated GIF images on iOS. It functions as an animation engine and image memory manager designed to ensure smooth frame transitions and consistent playback timing across different device environments. The project focuses on maintaining consistent animation speed through variable frame delay support and optimizes rendering efficiency to sustain high frame rates on mobile devices. It includes a memory management system to prevent application crashes and performance degradation during the playback of large or numerou
