Kong uses (and requires) LuaJIT, which is compatible with Lua 5.1, with some extra features from Lua 5.2 and 5.3, like `goto` and `table.move()`.

See [https://repo.or.cz/w/luajit-2.0.git/blob\_plain/v2.1:/doc/extensions.html](https://repo.or.cz/w/luajit-2.0.git/blob_plain/v2.1:/doc/extensions.html) for a list of extensions relative to Lua 5.1

short answer, no.

real answer: LuaJIT is not Lua. Both Kong and OpenResty (the underlying scripting platform) require LuaJIT features, like FFI, bit library, and a few others.

Do you require any specific Lua 5.3 feature? As mentioned, LuaJIT does copy a few.
