About CoolBG

CoolBG.com is an independent, free tool for generating procedural backgrounds directly in the browser — gradients, SVG patterns, and animated mesh canvases — with no image libraries, no accounts, and no watermarks.

Every background is produced by an algorithm the moment you load the page. Nothing is fetched from a database, and nothing you customize is uploaded anywhere — nothing leaves your browser until you choose to export or share it.

It's built and maintained as a small, focused project. If you spot a bug or have a feature request, reach out through the Contact page.
