I respect your effort, but too much animation may limit the usefulness of your tool, so perhaps it would be better to release a lite version with as little animation as possible. I tried the service, the search is a bit slow, but it provides an additional service to the services currently available.
It seems the issue with the website that loads slowly is not just because of too much animations, but more likely also because of a server outage. When I created Signatools a long time ago, I used a server with 2vCPU Core, and needed to think about how to prevent the scraping process consuming all the server’s resources at once. Perhaps OP also needs to find a way to resolve the CPU limit so users can load the page more smoothly. Because right now, based on several replies, and even when I tried it myself, the page just keeps loading without end.
