Lua Obfuscator Corpus
Dataset Summary
The Lua Obfuscator Corpus contains 26,357 Lua/Luau source files across 17 Lua/Luau obfuscators and 1,244 unobfuscated baselines. The dataset was created to support research into Lua/Luau code obfuscation detection, obfuscator identification, and code analysis. All files have been validated using tree-sitter-lua & luau parsers to ensure syntactic validity.

Dataset Structure
Data Fields
file_name(string): Relative path to the.luaor.luaufile.obfuscator(string): Name of the obfuscator used.obfuscated(bool): Whether the file is obfuscated.dialect(string): Lua dialect (luau).file_size(int): File size in bytes.version(string): Obfuscator version, if applicable.content(string): Full source code contents.
Data Splits
The dataset has no splits and all data is loaded as train split by default.
Dataset Creation
Source Data
Obfuscated samples were scraped from public open-source repositories or generated from a common set of unobfuscated Luau scripts using each obfuscator's CLI or web interface. Unobfuscated baselines are decompiled Roblox scripts.
