I think you're asking about automating the screenshot comparison, and there are some answers about that already. I wanted to chime in with a complementary comment.

We recently started using Vercel to host our front-end application, and out-of-the box, it automatically deploys every branch to it's own "Preview" environment. This has been game changing for me, inverting my review workflow. Before I look at the code, I typically test out the UX changes live.
