“If a game engine could run anywhere, how would the world change?”_
Fuel was born from this single question.
Fuel is a minimal C89 game engine with multi-arch JIT,
hardware-accelerated rendering backends, and platform-native audio
pipelines — built for production deployment.
It runs on any post-2000 computer, from under-resourced hardware to cutting-edge systems.
- Jot & Run — No boilerplates. Jot down an idea, and it comes alive.
- Lightweight — Runs even on small or older machines.
- Ultra Fast — Built-in JIT compiler brings ultra speed into your code.
- Go Far, Stay Close — Develop for distant platforms, with nothing but your own machine.
Here's a simple sample showing how to display an image at the mouse position.
Fuel is a lightweight and flexible game engine, designed to support creators across desktop, mobile, and console platforms.
It runs smoothly even on older or low-spec machines — if you have a computer, there's a place for you to create. 💻🌱
And if you're using something more powerful, like a modern MacBook or iPhone, Fuel adapts to draw out the full capabilities of your device. 🎮📱
You don't need the latest hardware. Fuel helps you go beyond your environment. It's a helpful companion for creators everywhere — especially in places with fewer resources.
Create at your pace, wherever you are in the world. 🌍✨

FuelLang (/ˈfjʊəlæŋ/, "fyool-lang") is a lightweight scripting
language designed specifically for Fuel. Featuring a game-oriented
syntax, it emphasizes clarity, instant startup, and seamless
integration with the engine.
Built-in JIT compiler supports multiple architectures: x86, x86_64, Arm32, Arm64, PowerPC32, PowerPC64, MIPS32, and MIPS64.
For platforms where JIT is restricted, its C source backend enables AOT compilation, making it ideal for mobile deployment.
Fuel uses dual-licensing.
Fuel is available as open-source software under the MIT License. You're free to use, modify, and share it — even in commercial projects. Please see the LICENSE file in the repository for full details.
Support is provided on a best-effort, community-driven basis. If you require guaranteed support, please contact the author to discuss an agreement.
On commercial game platforms such as Nintendo Switch™, PlayStation® 5, and Xbox Series X|S, the terms of each platform's SDK agreement may restrict the use of open-source libraries that are not expressly authorized by the platform holder.
To support compliance with such requirements, an NDA-based proprietary license of Fuel is available under the following conditions:
- Eligibility: Available to licensed developers with access to the official SDK and a signed NDA with Nintendo, Sony, or Microsoft.
- Distribution: A commercial version of Fuel is provided privately upon request and is not included in the public repository.
- Usage: The provided code may be integrated into your project and submitted as part of your own source code to satisfy platform submission requirements.
To request access, please contact the author with proof of your platform NDA status and a description of your development environment.
Fuel is for those who quietly hold a dream, and wish to share it, one small step at a time.
Creativity shouldn't depend on the power of your computer, where you live, or what tools you have.
Fuel was created with the hope that every creator deserves space to explore, no matter their surroundings.
Whether you're using a Raspberry Pi in a classroom, or using a UN-issued Chromebook in a temporary shelter, Fuel offers gentle tools to help bring your ideas to life — in a way that feels simple, thoughtful, and yours. If you have something to make, Fuel will be here to walk with you.
Dreams fuel it — and they're the only requirement.
Fuel is still in its early stages. We're building a game engine with care, hoping it will inspire and empower creators around the world.
If you're interested in contributing — whether it's code, documentation, testing, or ideas — we'd be happy to have you with us.
Every small step helps shape what Fuel can become. You're welcome to join us on this journey.
Awe (/aːwe/, "ah-weh") is a programmer living alone in a small house, surrounded by fields. They love writing code — it feels simple and clear. Understanding people's feelings takes time, but tools can be kind.
This software is Awe's small universe. Thank you for visiting. And thank you for receiving their seasoned craftsmanship.
Please use this dream-fueled engine with confidence. It was made for you, even before we met.
