Frequently asked questions

Is the contour lines background generator free?
Yes. beUI Studio is free to use in your browser, including exporting React source, PNG images, and WebM videos.
How do I add an animated contour lines background to a React app?
Open the background in Studio, adjust it, then export React source. Paste the component into your project and render it behind your content, for example as the first child of a hero section.
Will an animated WebGL background slow down my site?
It uses the GPU, so keep it to one background per view, avoid full-resolution canvases on low-power devices, and use the PNG export as a fallback for visitors who prefer reduced motion.
Can I change the colors to match my brand?
Yes. Every background takes your own palette, and you can tune speed, scale, detail, distortion, glow, grain, and color adjustments before exporting.
