raylib
raylib is a simple and easy-to-use library to enjoy video game programming. It is a programming library to enjoy video game programming; no fancy interface, no visual helpers, no GUI tools or editors, just coding in a pure spartan-programmers way. raylib does not provide the typical API documentation or a big set of tutorials. The library is designed to be minimalistic and be learned just from a cheat sheet with all required functionality and a big collection of examples to see how to use that functionality. The best way to learn to code is by reading code. raylib supports multiple target platforms, it has been tested in the following ones but, technically, any platform that supports C language and OpenGL graphics (or similar) can run raylib or it can be very easily ported to. You can use raylib with multiple programming languages, there are over 60 bindings. raylib can be combined with several extra libraries for additional functionality.

Ionic
The Ionic Platform allows you to bring your apps to market faster with an integrated app platform built on the leading cross-platform mobile SDK. Build, secure, and deliver new mobile apps—and transform existing ones—across iOS, Android, and Web platforms from a single codebase. Full scalability—Grow from prototype to production to enterprise-scale, without having to think about capacity, reliability, or performance. Better apps, everywhere—Slash your development time and costs with a platform that lets you write once and deploy anywhere—iOS, Android, and Web. The core of the Ionic development experience is Ionic Capacitor, a cross platform native runtime that runs equally well on native iOS and Android mobile devices, as well as any web browser. The big difference is that, unlike traditional native development or cross-platform approaches, the UI of a Capacitor app runs primarily in the browser.

Solar2D
Solar2D is a Lua-based game engine focused on ease of iterations and usage. As a fully open-source project forked from the well-established and widely used Corona SDK game engine, Solar2D allows developers to create applications for mobile, desktop, and connected TV devices with a single codebase, supporting platforms such as iOS, tvOS, Android, Android TV, macOS, Windows, Linux, and HTML5. The engine features an instant-update simulator, enabling developers to see code changes in real time, and supports live builds for rapid testing on real devices over a local network. A vast array of plugins is available to extend the core functionality, covering aspects like in-app advertising, analytics, and media. For additional customization, developers can call any native (C/C++/Obj-C/Java) library or API using Solar2D Native. Built on the lightweight and fast Lua scripting language, Solar2D is completely free to use, with no hidden fees, charges, or royalties.
