LemonUI is a lightweight and modern UI framework widely used in game modding, especially for creating clean in-game menus and interfaces. It is most commonly associated with GTA V mod development and is designed to work with .NET-based scripting environments. Because of its flexibility and simplicity, many developers prefer it over older UI libraries. However, it does not work on every modding platform, so understanding where it is supported is important before using it in a project.
In general, LemonUI integrates best with ScriptHookVDotNet and other C#-based modding tools, while also having partial or indirect compatibility with platforms like RagePluginHook and FiveM depending on configuration. Knowing its supported environments helps developers build stable, functional, and visually appealing mod menus without unnecessary compatibility issues or technical limitations.

What is LemonUI?
Before diving into platforms, it’s important to understand what LemonUI actually is.
LemonUI is a user interface library designed for .NET-based game modding. It helps developers create interactive menus, buttons, lists, and notifications inside games without needing to build UI systems from scratch.
It is especially popular in GTA V modding because it offers:
- Clean and modern UI design
- Easy integration with C# scripts
- Lightweight performance
- Compatibility with script-based mod loaders
Because of its simplicity, it is widely used in both single-player and multiplayer modding environments.
ScriptHookVDotNet (Primary Support Platform)
The most important and widely used platform for LemonUI is ScriptHookVDotNet.
This is the core environment where LemonUI was originally designed to work.
Why it works so well here
ScriptHookVDotNet allows developers to write C# scripts that run inside GTA V. LemonUI integrates smoothly because both are built around the .NET ecosystem.
Key advantages
- Full support for C# scripting
- Direct access to GTA V native functions
- Stable and widely documented environment
- Easy menu creation using LemonUI components
Most GTA V single-player mods using menus rely on this combination because it is stable and beginner-friendly.
RagePluginHook (RPH)
Another strong platform supporting LemonUI is RagePluginHook.
RagePluginHook is also used for GTA V scripting but focuses more on plugin-based modding.
How LemonUI works here
Since RPH supports .NET plugins, LemonUI can be used to create in-game menus and UI elements similar to ScriptHookVDotNet.
Benefits in RPH
- Strong plugin architecture
- Stable for single-player mods
- Supports advanced scripting features
- Good compatibility with UI frameworks like LemonUI
However, developers sometimes need minor adjustments depending on project structure.
FiveM (Partial / Adaptable Support)
One of the most asked questions is whether LemonUI works in FiveM.
The answer is: yes, but with limitations.
FiveM primarily uses Lua, JavaScript, and C# for scripting, but its UI system is usually built with NUI (HTML/CSS/JS).
How LemonUI fits in FiveM
- Can be used in C# server/client scripts
- Works in certain environments where .NET is enabled
- Not the standard UI approach in FiveM
Limitations
- Not as widely used as NUI
- May require additional configuration
- Compatibility depends on server setup
So while LemonUI is possible in FiveM, most developers prefer NUI for full UI systems.
Unity Modding (Indirect Use)
LemonUI is not natively built for Unity, but it can still be used in certain modding scenarios where .NET assemblies are supported.
When it works
- If the game uses Unity with C# modding support
- If the mod loader allows external UI libraries
- If custom integration is implemented
Important note
Unity modding usually relies on built-in UI systems (like Unity UI or IMGUI), so LemonUI is not a standard choice here. It’s more of a custom solution than a plug-and-play option.
OpenIV (Not a Direct Platform)
Many beginners confuse modding tools with platforms. For example, OpenIV is often mentioned.
However:
- OpenIV is NOT a scripting platform
- It does NOT support LemonUI directly
- It is only used for editing game files (textures, models, archives)
So while it is essential for GTA V modding, it does not run UI frameworks like LemonUI.
Other Experimental or Custom Frameworks
Some developers also integrate LemonUI into custom modding frameworks, especially when:
- Building private mod menus
- Creating trainer tools
- Developing experimental plugins
In these cases, LemonUI is used as a dependency inside a .NET-based runtime rather than a full platform.
Summary of Platform Support
Here is a quick overview:
- ScriptHookVDotNet → Full and primary support
- RagePluginHook → Strong and stable support
- FiveM → Partial / configurable support
- Unity modding → Indirect or custom integration
- OpenIV → No support (tool only)
Conclusion
LemonUI is a powerful and easy-to-use UI framework, but its effectiveness depends on the modding platform you choose. It works best in .NET-based environments like ScriptHookVDotNet and RagePluginHook, where it offers full support for creating smooth and responsive in-game menus. On platforms like FiveM, its use is more limited and often replaced by web-based UI systems, while tools like OpenIV do not support it at all since they are not scripting platforms.For developers, the key takeaway is simple: if you are working in GTA V single-player modding with C# support, LemonUI is an excellent choice. Understanding platform compatibility ensures better performance, fewer issues, and a more stable modding experience overall.
