It takes "a lot" of dedication and commitment to compromise a website/database. If you want to fall In the category of wannabe hackers, go ahead and use Kali Linux. If not, do It via your own volition and spend 16+ hours a day by way of manual exploitation.

It Is way beyond the scope of this post to document every exploit & attack vector. It'll take me an entire week (at the minimum) to go through the "basics" of Content-Based/Boolean-Based, Inferential/Time-Based, Out-Of-Band & particularly Union-Based SQLi.

I tried kali Linux but didn't go well with any website even with LOW PROTECTION and I spent 40+ hours doing everything RIGHT

Don't waste your time with Kali Linux.

what would you suggest other than Kali Linux?
