A little open-source utility from Tyler Sticka that returns a data URL of an SVG to use as an image placeholder as needed.
I like the idea of self-running utilities like that, rather than depending on some third-party service, like placekitten or whatever. Not that I’d advocate for feature bloat here, but maybe it could be more fun like these generative placeholders, marching ants, or my favorite, adorable avatars.
This is my favorite https://avatars.dicebear.com/
