That hub is in Pre-Early development.
(Most of scripts are not mine)
-How to use Koala Hub? -First you need an executor, I recommend to use paid executors, because in free ones you will need a key every 24h/48h.
-Which free executor is the best? -Krnl (Runs ~90% of scripts, but updates too long and got 24h key system).
-Which paid executor is the best? -Synapse (I recommend it, runs all scripts, keyless, costs 15-20$ (15$ only with crypto)), Sentinel (Runs ~95% of scripts, keyless, cost 15$). (I don't recommend because: others other exploits are not popular | updating too long | just closed)
-Can I use my own executor? -Yes
