Is it safe to use Roblox executors while learning Lua?

Hi everyone,

I’ve just started learning Lua with Roblox and I keep hearing about “executors” that let you run scripts inside the game. Some people say they’re useful for testing, but I’m worried about safety and performance issues.

One example I found is Fluxus Executor, which supports Windows, Android, and iOS. I even checked their documentation, but I’m still unsure if it’s safe for beginners to try.

So my questions are:

• Can using executors cause lag or slow down your system?
• Are there risks of viruses or account bans?
• Has anyone here used something like this while learning Lua?
• Would really appreciate your advice before I give it a try.

Thanks!
