    raylib-go

    raylib-go

    Go bindings for raylib, a simple and easy-to-use library

    ...It allows Go developers to build 2D (and some simple 3D) games, graphical applications, or multimedia tools using a familiar and simple API, while leveraging Go’s language ergonomics, concurrency model, and ecosystem. With raylib-go, developers can draw graphics, handle input, play sound, manage textures, and manage game loops directly in Go — without needing to write or interface with C manually. This makes it a good choice for those who prefer Go over C/C++, but still want a simple, straightforward engine for fast prototyping or small-to-medium games. Because raylib is known for simplicity and ease of use, raylib-go carries that over to the Go ecosystem: you can get up and running quickly, which is ideal for hobbyist developers, game jams, prototypes, or small indie games. ...

    OpenTK

    OpenTK

    The Open Toolkit library is a fast, low-level C# wrapper for OpenGL

    ...It runs on all major platforms and powers hundreds of apps, games, and scientific research programs. OpenTK provides several utility libraries, including a math/linear algebra package, a windowing system, and input handling. OpenTK is not a game engine, nor does it try to be one: It offers a useful set of tools and lets you decide how to use them. It is the ideal starting point if you want to write a game or scientific application from the ground up. The OpenGL specification specifies exactly what the result/output of each function should be and how it should perform. ...

    Redot Engine

    Redot Engine

    Multi-platform 2D and 3D game engine

    Redot Engine is an open-source game engine that aims to provide a flexible foundation for building games — likely offering a modern, modular structure so developers can compose only the systems they need (rendering, physics, input, scripting, etc.). It is built to give a base framework rather than a full “batteries-included” engine, which makes it suitable for developers who prefer minimalism, want complete control over architecture, or desire to build custom workflows. Because it’s open-source, Redot-Engine is potentially community-driven, allowing anyone to inspect, extend, or customize core functionalities. ...

    dhewm3 is a source port of the original Doom3 (not Doom3 BFG, for that you may want to try RBDoom3BFG). It’s known to work on Windows, Linux, macOS, FreeBSD, OpenBSD and AROS, but it should work on (or be easily portable to) any system that supports OpenGL 1.4 with ARB shaders, SDL and OpenAL. Compared to the original version of Doom3, dhewm3 has many bugfixes, supports EAX-like sound effects on all operating systems and hardware (via OpenAL Softs EFX support), has much better support for...

    Mach Engine

    Mach Engine

    Zig game engine & graphics toolkit

    Mach is a game engine and graphics toolkit written in Zig, built with the goal of enabling high-performance, truly cross-platform 2D, 3D, GUI, and visualization applications. The project aims to deliver a modular, robust foundation where graphics, input, windowing, and rendering are unified under a modern, low-level but ergonomic API. Because Mach is written in Zig (with some shader code / WGSL), it leverages Zig’s performance and modern systems-level features while offering safe-ish abstractions compared to raw graphics APIs. The engine supports a broad set of target platforms — desktop OSes and in principle, future expansion — and tries to simplify the pain of dependency management and cross-compilation, making it easier to build and deploy across systems without complex toolchains. ...

    The ioquake3 community effort to continue supporting/developing id's

    ...It is designed to let players run Quake 3, its expansion Team Arena, and community mods on contemporary systems while also serving as a solid base for new projects. The engine modernizes the original codebase with a CMake build system, an SDL2 backend for cross-platform windowing and input, and OpenAL sound for better audio quality and multi-speaker setups. It adds numerous quality-of-life improvements such as VoIP support, AVI demo capture, improved console completion and history, and optional Ogg Vorbis support. ioquake3 also improves portability and maintainability by supporting x86_64 on Linux, MinGW builds on Windows, and various other operating systems, and even provides web support via Emscripten.

This means things like basic UI elements, text rendering, advanced input handling (textboxes) and performance overlays are provided out-of-the-box. Any of the osu! code that is deemed useful to other game projects will live in this framework project. Anywhere we implement graphical components, they will be displayed with a generic design and will be derivable for further customization.

    macroquad

    Cross-platform game engine in Rust

    ...The library is heavily inspired by simpler game frameworks (like raylib), but brings the ergonomic and safety features of Rust to 2D — and some minimal 3D — development. With Macroquad, you don’t need to worry about low-level graphics plumbing: it handles window and input management, rendering, UI, and more, letting you focus on game logic. A strength of Macroquad is its cross-platform reach: it supports desktop (Windows, Linux, macOS), web (via WebAssembly / HTML5), and mobile (Android, iOS) without requiring platform-specific code. Compilation is relatively fast with minimal dependencies, so small projects or prototypes can spin up quickly. ...

    ...Gosu is focused, lightweight and has few dependencies (mostly SDL 2). It provides a window and a main loop. 2D graphics and text, powered by OpenGL or OpenGL ES. Sounds and music, keyboard, mouse, and gamepad input. Gosu is mostly used to teach or learn Ruby or in short game development competitions. It’s also a great prototyping tool and should work for indie game development, though nobody has really tried that. In addition to the documentation linked from the sidebar, there is a free book by Mark Sobkowicz that will guide you through the creation of four different games.

    Murder Engine

    Murder Engine

    Murder is a pixel art ECS game engine

    ...Because Murder is in active development and still relatively young, the authors warn that breaking changes are possible — but this also means the engine is evolving rapidly as features are added and refined. Using Murder, you get a lot of the low-level plumbing handled: rendering, input, update-loop, resource loading — so you can focus on actual game logic, art, and design instead of boilerplate. It powers projects like games built by its creators and even won a game-jam with one of those, demonstrating that despite its youth, it's already production-capable. For developers comfortable working in C# and aiming for indie 2D games.

    Mini game engine for games104

    Piccolo is a software project oriented toward offering a flexible, probably modern game or application engine/framework, designed to be lightweight and open — giving developers the ability to build custom interactive applications or games without massive overhead. It aims to strike a balance between usability and freedom: providing core building blocks (rendering, input, asset management, maybe UI) while leaving higher-level design decisions up to the user. Its architecture is likely modular and minimalistic, avoiding heavy assumptions or “one-size-fits-all” paradigms. As an open-source project, Piccolo allows developers to inspect and modify internal workings, integrate external libraries or modules as needed, and adapt to unconventional or experimental use cases. ...
