Measured entry

uilayouts-mesh-shadergradient

background-effectaurora-meshmotion on file

A client-side animated mesh background built from ShaderGradientCanvas and ShaderGradient. It ships as a shadcn registry component, fills the viewport through Tailwind classes, and depends on @shadergradient/react for the rendered sphere, camera, lighting, grain, and motion.

Verdict

It builds and mounts cleanly without a provider, and the shader delivers a distinctive dark, grainy color field. Still, its viewport-sized wrapper overflows every tested layout and the dependency is costly, so it fits selective hero use better than a default site background.

Use it if

  • You need a cinematic animated backdrop for a hero or campaign page.
  • Your app already accepts client-rendered WebGL effects and their runtime cost.
  • You can place foreground content in a separate layer and tune the shader colors to the page.

Skip it if

  • You need a contained background that must not overflow its section or viewport.
  • Your bundle budget cannot absorb a large shader dependency.
  • You need built-in reduced-motion behavior or a static fallback.
  • Your audience commonly uses devices or browsers where WebGL effects are unreliable.

In a non-shadcn project, install @shadergradient/react, copy the client component, and provide Tailwind utilities or equivalent styles for its viewport wrapper. Add overflow containment, a reduced-motion or static fallback, and ensure the component renders only on the client where WebGL is available.
