Open-source alternatives to Pyglet

Toga is a cross-platform application framework and native GUI toolkit for Python. It serves as a multi-platform frontend wrapper that allows a single codebase to be deployed across macOS, Windows, Linux, Android, and iOS. The toolkit functions as a native widget UI library, mapping high-level Python interface definitions directly to the host operating system's own visual components. This ensures that applications use native system widgets to match the look and feel of the target environment rather than relying on custom drawing libraries. The framework covers cross-platform development for d

Cross-platform 2D framework written in Haxe that can export natively to desktop (windows, mac, linux), mobile (ios, android), web (js webgl) and to unity projects

Gooey is a framework that transforms command-line programs into graphical applications by automatically generating user interfaces from existing argument definitions. By applying a decorator to a script, the tool maps standard command-line arguments to specialized graphical widgets, allowing users to interact with terminal-based utilities through forms, file pickers, and date selectors. The project distinguishes itself by providing a comprehensive suite of customization and lifecycle management tools that extend beyond simple interface generation. It includes capabilities for input validation

Cross-platform 2d game framework

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

I'm Ivan Polyacov and this is my code library which I'm making and using in my games and other projects since early 2000x at Apus Software. It is used in many games including Spectromancer, Astral Heroes and others. Most code I wrote myself, but some minor parts were taken from other sources.…

JavaScript Game Engine

We recently reset this repository for working on a new version, at the moment we're making experiments. If you are looking for the old one, find it here.

Oasis Engine is a web-based game engine and component-based game framework designed for creating real-time interactive 2D and 3D applications for web and mobile platforms. It functions as a real-time 3D renderer and a physics simulation engine capable of producing interactive visual environments. The framework includes a visual scene editor that allows artists and developers to build, layout, and export project scenes through a graphical interface. This system supports visual scene composition and converts these layouts into structured data for runtime reconstruction. The engine's capabiliti

A multi-platform Vulkan / WebGPU / OpenGL game engine that works on Desktop Java, Android and browsers.

Pixel is a 2D game library and graphics engine for the Go programming language. It provides a hardware-accelerated renderer for drawing sprites, geometric shapes, and text, utilizing an optimized system of batching and transformation matrices. The project functions as a comprehensive toolkit for two-dimensional interactive applications, combining a graphics engine with a 2D vector math library for affine transformations and coordinate space projections. It includes a dedicated input manager that tracks keyboard presses and mouse movements using a polling-based system rather than asynchronous

Flet is a cross-platform framework that enables developers to build interactive desktop, mobile, and web applications using only Python. By utilizing a declarative programming model, it allows for the construction of complex user interfaces through a hierarchical structure of components, removing the need for specialized knowledge of web-specific languages like HTML, CSS, or JavaScript. The framework distinguishes itself by offloading visual rendering to a high-performance graphics engine while maintaining application logic within a centralized server-side environment. This architecture synch

Please note that Oryol is currently not actively maintained and hasn't been for a long time, my focus is currently on the Sokol headers and (from time to time) on the Chips emulator stuff.

FNA - Accuracy-focused XNA4 reimplementation for open platforms

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

Halley is a modular C++ game engine designed for building cross-platform interactive applications. Its core identity is defined by a hardware-abstraction graphics pipeline for consistent rendering across different operating systems and an entity-component-system architecture that separates game state from processing logic. The framework features a hot-reloading development environment that allows updating application logic and assets at runtime without requiring a full process restart. It also includes a multiplayer networking framework based on an asynchronous messaging system to manage real
