I use a client called Onix client. Its a PvP client that can display keystrokes, combo counters and all sort of other things. Its not to be confused as a hack client. None of the modules give you an advantage besides stuff like zoom free look and full bright.

If its a banned client please tell me because I would like to use it in my speedruns and if zoom and freelook are banned then would I be able to use other modules like Keystrokes and combo counter.

I just need to know if the client is banned completely and if I just cant use stuff like zoom and freelook.

The difference between Onix and similar clients and hacked clients is that normal clients will modify what you see on your screen, whereas hacked clients modify the data that you send to the internet. So, while Onix isn't like kill aura, there are questions like "is Xray bannable?" that come up when normal clients are allowed (basically people ask if anything that isn't technically a hack is allowed). Onix does give some pretty serious advantages to its users, but in most cases it doesn't really replace skill (whereas a hacker doesn't need to be skilled).

I don't know whether it's bannable, it would make sense to me either way.

Onix Client is a client allowed by CubeCraft! You’re able to use both freelook and zoom as well in your speedruns—your runs would not be rejected as the client isn’t prohibited by the server.
