Yes, that’s right. I found a very old version of the Perchance welcome page dated back on August 12, 2018. It was very basic, and Perchance was even still considered in beta at that time. When you look at the source, though, it might be a little modified, but the overall structure of the page is still intact.
There isn’t much changed from the outlooks, but if you look closely there is only one “Start Learning” button below the example code section, there is no video tutorial section, there is no instruction on how to embed a generator (which I guess is still not a thing at that time) and there is even no “try this example” button that redirects to this example that was also linked in the old page somewhere nearby.
