Moonarc, 102 motion components for Astro, each shown next to the JavaScript it actually costs, measured from a real build. 67 of them ship zero JS.
I built the catalogue around the question a developer asks before adding an effect: what will this do to my page? Every tile is the live component, and the byte count under it comes straight out of the build.
The same hero built twice makes the point. Five effects on Moonarc's runtime come to 7.5 kB. The same five in a React island with Framer Motion come to 350.5 kB.
Pro adds 11 WebGL effects and 28 page sections, each tested for memory leaks and lost GPU contexts. Works on Astro 5, 6 and 7.
