MonoGame

MonoGame is an open-source game development framework built on C# and .NET. It's aimed at developers who want full control over their code without paying engine licensing fees or royalties. Unlike commercial engines, there's no subscription model and no runtime fees, ever.

The framework targets a wide range of platforms from a single codebase:

• Desktop: Windows, macOS, and Linux
• Mobile: Android, iOS, and iPadOS
• Console: PlayStation 4, PlayStation 5, Xbox One, and Nintendo Switch (console access requires approved developer status)

All source code is publicly available. If you hit a platform-specific limitation or want to port to something new, you can modify the framework itself. That's a real advantage over closed tools where you're waiting on a vendor to fix something.

MonoGame is owned by the MonoGame Foundation, a registered non-profit that depends on community donations rather than commercial revenue. That structure keeps the tool free and community-driven rather than tied to a company's roadmap.

It works with the editors developers already use: Visual Studio, Visual Studio Code, and JetBrains Rider. The C#/.NET foundation means you get modern language features, strong tooling, and a mature ecosystem for things like debugging and profiling.

If you're coming from a higher-level engine like Godot and want something closer to the metal with no abstraction layers between you and the rendering loop, MonoGame gives you that. It's a framework, not an editor-driven engine, so you're writing code rather than clicking through a scene graph. That suits developers building custom engines on top of it or porting existing games from XNA, which MonoGame was originally designed to succeed.
