ursina
A game engine powered by python and panda3d
ursina is an easy-to-use, open source game engine and framework for Python that is built on top of Panda3D, aiming to make game development approachable while still being powerful enough for real projects. It lets you create both 2D and 3D games, applications, and visualizations by writing concise Python scripts instead of dealing with a lot of low-level boilerplate. The engine is centered around an Entity-based architecture, where everything in the scene is an object you can easily configure and manipulate from code. Ursina focuses heavily on iteration speed, offering in-game reloading of code, textures, and models so you can tweak and test changes quickly. It includes many batteries-included features such as a mesh API for procedural geometry, built-in animation and tweening, pre-made controllers like FirstPersonController and EditorCamera, and a library of shaders and 3D primitives. -

Amazon Lumberyard
Amazon Lumberyard is a free AAA game engine
Amazon Lumberyard is (or was) a free AAA-capable game engine developed by AWS, with deep integration into AWS cloud services and the Twitch streaming platform. It provided full source access and offered developers tools to build high-quality games and simulations with networking, rendering, physics and cloud backend features built in. The engine allowed game creators to hook into AWS infrastructure for multiplayer services, analytics, voice chat, and more, and leveraged Twitch to build live-stream-enabled experiences. Although Amazon has since archived the repository and transitioned focus to the open-source successor Open 3D Engine (O3DE), the project remains of interest as a large-scale example of cloud-enabled game engine architecture. Developers studying game tech or infrastructure integration can inspect how the engine’s subsystems were designed, including entity/component architectures, rendering pipelines and networked game services. -

Descent 3
Descent 3 by Outrage Entertainment
The Descent3 repository is the open source release of the Descent 3 game engine by Outrage Entertainment, maintained by the community under the GPL-3.0 license. It provides the full C and C++ engine source code, including the historically significant “1.5” patch that was previously created by developers and later stabilized by fans. The codebase covers the game’s rendering, physics, audio, networking, tools, and editor components, allowing enthusiasts to build, run, and modify the classic 6-degrees-of-freedom space shooter on modern systems. To actually play the game, users must supply their own original game assets, following instructions in the repository’s usage documentation. The project uses CMake and related modern tooling for cross-platform builds, with support for Linux and Windows among other environments. A dedicated community maintains the engine, publishes updated releases, documents internals on a wiki, and coordinates contributions via an active Discord server and GitHub. -

Matter.js
A 2D rigid body physics engine for the web
Matter.js is a flexible 2D rigid body physics engine written in JavaScript, designed for use in web applications to simulate real-world physical interactions within the browser. It offers a comprehensive set of physics features like gravity, collisions, restitution (bounces), friction, sleeping bodies, and constraint systems that enable developers to build interacting objects with realistic motion. This engine can power everything from dynamic interactive animations and educational simulations to fully fledged physics-based games, and it works across major browsers and devices. Through modules such as Matter.Body, Matter.Composite, and Matter.Constraint, developers can create complex scenes with multiple bodies, jointed structures, and collision responses. Matter.js is popular in the web development community due to its simplicity, extensibility, and rich documentation, allowing both beginners and experienced programmers to leverage physics without deep expertise. -

Hypackel Engine
JavaScript-based game engine designed to empower developers
Hypackel Engine is a JavaScript-based 2D game engine designed to provide beginner-friendly tools for creating simple games such as platformers, RPGs, and top-down shooters. It focuses on accessibility by offering a lightweight and easy-to-integrate script that developers can import directly into web-based projects. The engine includes built-in systems for handling physics, collisions, rendering, and animation, allowing developers to focus more on gameplay logic rather than low-level implementation details. Its architecture is structured around modular systems like sprites, particles, and audio, which can be controlled through simple function calls and arrays. The project emphasizes simplicity and rapid prototyping, making it suitable for educational purposes or small-scale game development. It also includes example files and documentation to guide users through setup and usage. Overall, HYPACKEL-ENGINE-1 serves as an entry-level framework for experimenting with game development. -

Spartan Engine
A game engine with an emphasis on real-time cutting-edge solutions
SpartanEngine is a C++ game engine focused on cutting-edge real-time rendering and simulation, developed primarily as a long-running personal research project and now grown into a community-driven platform. It centers around a modern Vulkan renderer (with an in-progress DirectX 12 backend) and a fully bindless, unified deferred rendering pipeline designed to handle hundreds of millions of instances. The engine implements a wide range of advanced graphics features, such as atmospheric scattering, physically based shading, screen-space shadows and ambient occlusion, screen-space reflections, sophisticated shadow mapping, volumetric fog, and HDR output. It supports next-gen performance and image quality technologies including variable rate shading, dynamic resolution scaling, temporal anti-aliasing, and upscaling via XeSS 2 and FSR 3. Beyond rendering, SpartanEngine offers PhysX-powered physics, CPU and GPU profiling, a thread pool for parallel workloads. -

nunuStudio
Web powered cross-platform 3D, WebXR game engine
nunuStudio is an open-source editor + game development environment — a “studio” rather than just a library — designed to let developers create interactive 2D and 3D content through a user-friendly interface. It provides visual tools for scene editing, asset management, materials, and possibly scripting, aiming to reduce the friction of hand-coding every aspect from scratch. As an accessible entrypoint to game or interactive content creation, nunuStudio is well-suited for artists, designers, or developers who prefer a WYSIWYG (what you see is what you get) workflow instead of fully coding everything. Because it is open source, users can inspect, modify, or extend the system as needed — adding custom behaviors, plugins, or export options. It’s ideal for rapid prototyping, small games or interactive demos, or educational purposes: you can build scenes, tweak visuals, test interactivity without deep diving into all low-level rendering details. -

Ambient
The multiplayer game engine
Ambient is an open-source, cross-platform runtime and engine for building and deploying high-performance multiplayer games and 3D applications, using a modern stack built on Rust, WebAssembly (WASM), and WebGPU. It aims to make multiplayer game development accessible and flexible, providing an entity-component-system (ECS) at its core that doubles as a real-time in-game database; everything in the game — from world objects to runtime data — is represented as entities + components, which can be synchronized across clients automatically. Ambient supports a package-based workflow reminiscent of Rust’s crate system, where “packages” bundle code, assets, and schema definitions; this modular design encourages reuse, mixing, and sharing of content. The engine includes an asset pipeline that can stream and load common 3D formats (e.g. GLB, FBX) on demand, so players don’t need to pre-download large asset bundles — the engine handles asset streaming.
