Hi everyone, today I’m here to announce a major change to the Studio experience for the community
RML is a modding framework for Roblox Studio that lets you write native C++ mods, .NET/C# mods, and (soon) internal Luau scripts - all loaded directly into the Studio process.
It works by hooking into Studio at the engine level, using the same Reflection abstraction to expose Roblox’s API to C# mods, and enabling you to execute core internal Luau scripting.
Mod types supported:
Native (C++) You can use for hooking engine level functions
.NET (C#) - YES, you can use the entire Roblox API using only C# (This is basically an unofficial implementation of C# on engine.)
Luau (internal scripting) - temporarily disabled, see note below
Heads up: this is alpha software
RML is still early. Expect bugs, crashes, missing features, and breaking changes between versions. A few things to know going in:
- Internal Luau/script support is currently disabled. Roblox shuffled the internal Luau struct layout a few months ago, so the old memory offsets no longer line up. I’m building a static-analysis dumper to reconstruct the correct structs before re-enabling scripting. Native C++ and .NET mods are unaffected and work normally.
- The launcher isn’t finished yet — manual install (extract the release into your Studio folder) is the reliable path for now.
- Only Windows and Linux/Vinegar is supported right now. macOS are on the roadmap but not there yet.
- The .NET modding API is still basic — better ergonomics and async support are planned, not done.
Quick Start
Manual install:
- Download the latest release: Releases · revolutionxk/roblox-modloader · GitHub
- Open your Studio directory (the folder with RobloxStudioBeta.exe, usually %LOCALAPPDATA%\Roblox\Versions<version>)
- Extract the archive into that folder
- Start Roblox Studio
Examples to get you started
- basic-mod (C++) — minimal native mod skeleton + hooking entry points
- internal_developer (C++) — enables Studio’s internal developer tools
- discord_rpc (C++/Luau) — Discord Rich Presence, native + script bridge
- example_dotnet (C#) — Services, Instances, properties and events via the typed API
- discord_rpc_dotnet (C#) — a managed Discord Rich Presence integration

Roadmap
- Finish the dumper (re-enable Luau/internal scripting)
- Better .NET modding API (async support, callback, tuples etc.)
- Mod browser & installer
- macOS support (long-term)
