ReflectionService is not enabled?

mattqdev · July 1, 2025, 4:26pm

I just discovered the existence of the game:GetService("ReflectionService") service because I was looking for a way to iterate and get information about all the methods of a service (I haven’t succeeded yet, so if you can help me I would be very grateful).

The problem is that the documentation on this service is practically empty and useless. Every method when called gives me this error:

I can’t figure out what the methods do and how to use them. There is no guide or support.
I am convinced that this service is abandoned to itself even though it could be useful.
If it is deactivated I would like them to write it or even better activate it.

I don’t really know but my guess is that it is still in development.

But that is questionable since it seems like the last update they did was in 2023:

Edit: As @0x1437 mentions later, the link above does not contain updated information.

I also don’t know how to iterate methods from a services via plugin script

It’s as it states, the methods you are trying to use are not enabled.

Do you think it will be enabled sooner or later or has it been completely abandoned?

This is such a useful function, especially for my Instance Serializer project.

Anyways, it can be enabled by setting DFFlagNewReflectionService to true

I believe it will be enabled sooner. All they have to do is literally toggle an FFlag

Any other information you could show? Is it true that the last update was in 2023?

0x1437 · July 12, 2025, 11:55am

What kind of information do you want to know?

No. They have added new functions to ReflectionService at version 671, which was at 2025-04-29 15:35.

What you initially shared in your comment above was /ref-temp, not the updated /ref
