How to use KRNL - YouTube

KRNL is the best free exploit you can use and might be even better than Synapse but the bad thing about KRNL is that you have to get a new key every 24h, to get it you have to go through 4 Linkvertise links

     Vega X v2.1.3

Link for the exploit - Mega.nz

It's for free and with no key, but some scripts might not work with it

Credit to Vega X maker - 1 F0

Synapse X (paid)

If you are ready to pay for an exploit, Synapse X is the perfect choice as it is the best exploit - https://x.synapse.to

Script-Ware (paid)

What is really good about Script-Ware that it works with MacBook and is a really good exploit in general
