etc.

Known errors:

Cannot decompile while and repeat loops, May cause some errors since its in beta

Usage:

local decompile = require("Decompile")
local bytecode = "bytecodestring" -- this is an example this will not work
local code = decompile(bytecode)

Sandbox usage:

Please install luau and vLuaU Compiler. You can get it from here (No need to install luau if you have studio)

local str = [[
-- script here
print("Hello, World!")
]]

local compile = require(script.compiler).luau_compile
local decompile = require(script.decompiler)
local bytecode = compile(str)
print("Original bytecode: "..bytecode)
print("Decompiled bytecode: "..decompile(bytecode))

Enviromental usage:

local decompile = require(script.Decompile)
local bytecode = getscriptbytecode(scriptPath --[[Replace with script path smth like game.ReplicatedFirst or smth like that]]) -- this will generate real bytecode
local code = decompile(bytecode) -- returns the code from that bytecode
