Luadec is one of the oldest and most well-known decompilers for Lua 5.1. While it hasn't seen much development for newer versions, it remains the gold standard for legacy projects and many older game engines. 2. Unluac (The Reliable Java Tool) Depending on your target and version, here are
Before using a Lua decompiler, it is important to consider the legalities. Reverse engineering software is a gray area that depends heavily on your local laws and the End User License Agreement (EULA) of the software. Generally, decompiling for personal learning or security research is acceptable, but redistributing decompiled code or using it to bypass digital rights management (DRM) can lead to legal issues.

Games like Roblox use Luau , a derived version of Lua with a custom bytecode format that requires specialized tools. Top Lua Decompiler Tools
