debug.getregistry

Returns the Luau registry - the table the VM keeps its internal references and loaded libraries in.

debug.getregistry(): table

The same table object comes back on every call. Its direct contents are the VM’s live internal references (threads, functions, userdata) plus _LOADED - every library and module required this session. The threads sitting in here are what getscriptfromthread walks to map a thread back to its owning script.

Returns

table - the live registry. The same object is returned on every call.

Key	What’s in it
_LOADED	Every library and module required in this session.
Internal keys	Live VM references the engine holds - threads, functions, userdata.

Use caution when modifying registry values, as it can cause instability in the Lua VM.
