Wave is a free browser-based tool that generates layered, animated gradient wave backgrounds using Three.js and WebGL shaders — giving you the kind of soft, depth-rich motion graphics that would otherwise require shader coding knowledge or expensive motion tools. It outputs visuals suitable for social posts, landing page heroes, and presentation backdrops without writing a line of code. The WebGL foundation means the results look genuinely premium compared to typical CSS or SVG gradient generators.

Why it stands out

The shader-based rendering produces soft volumetric shadows and smooth color blending that CSS gradients and SVG simply can't replicate, giving outputs a tactile, almost physical quality. For a free, no-install static tool, the visual ceiling is surprisingly high.

Best for

A generalist designer who frequently needs polished hero backgrounds or social assets and wants something more distinctive than the sea of mesh-gradient PNGs everyone else is using.
