Haikei
haikei.app
A web app for generating layered SVG backgrounds, waves, blobs, gradients, and geometric patterns — with randomize and fine-tune controls and export to SVG or PNG.
Why it is useful
The fastest way to produce unique, polished background graphics without opening Illustrator. The wave and blob generators in particular produce shapes that would take significant manual effort in a vector editor. Because output is SVG, backgrounds scale perfectly at any resolution. Each generator has enough randomization and control that you can iterate quickly to something that looks genuinely designed.
