Lua analysis.Execution trace.

Analyze Lua 5.1, Lua 5.3, and Luau. Review program output, then follow each simulated operation with its call depth and source location in a downloadable execution trace.

hello.lua
local function sumTo(limit)
local total = 0
for value = 1, limit do
total = total + value
end
return total
end
return sumTo(10)

What the analyzer shows

Choose Lua 5.1, Lua 5.3, or Luau, then inspect return values, printed output, and each recorded operation. Explore functions, tables, string patterns, binary buffers, file fixtures, and selected Roblox client behavior.

Reports show syntax and runtime errors, execution steps, output, return values, and observed strings with source positions and exact bytes. Luau Modded Client can use the HTTP responses and files you provide for an analysis.
