EduBlocks allows you to create a website without knowing the HTML or Python coding language. It can be used for other forms of coding but for a website you would select HTML or Python.
It's free to use and there are tutorials on you tube to help you or go to the "Showcase" and "Guides" pages to see examples.
It also allows you to see what the HTML or Python code is that you are creating using the blocks.
Great tutorial to get you going on EduBlocks making a website
