Measured entry

cultui-grid-beam

background-effectgradient-glowmotion on file

A client-side React background effect shipped as a shadcn registry source file. It combines a canvas animation, SVG grid dividers, palette presets, and composable helpers. It declares no extra packages, but assumes React, Tailwind-style utilities, a cn helper at the usual alias, and browser animation and resize APIs.

Verdict

A flexible, well-factored grid effect that built, mounted, and adapted cleanly in the configured harness. It is not standalone: bare mounting fails because the local utility import is absent, so it needs a shadcn-style setup or a small integration pass.

Use it if

  • You need an animated grid backdrop behind hero, feature, or system-flow content.
  • You want preset color themes plus controls for activity, pace, intensity, and grid density.
  • You want either an opinionated wrapper or headless pieces for a custom composition.

Skip it if

  • Your interface avoids continuous canvas animation or must minimize client-side rendering work.
  • Your project does not use Tailwind-style utilities and you do not want to translate the supplied classes.
  • You need a drop-in component with no local alias, utility helper, or theme-token setup.

Install

Bare installfails once the shadcn-style helpers are removed, so it needs that setup
Providerno provider required in the harness

For a non-shadcn project, add or replace the cn class-merging helper and its import alias, provide equivalents for the Tailwind utility classes and border theme token, and render it as a client component in an environment with canvas, ResizeObserver, matchMedia, and animation-frame support.
