Smooth by construction
Control points sit around a circle at jittered radii (Complexity sets how many, Randomness how far they stray) and are joined by a closed Catmull–Rom spline written out as cubic Béziers. That keeps the outline smooth at every point, with no kinks to fix by hand.
Layered mode stacks shrinking blobs for a ripple effect and Scattered drops several across the canvas. Turn on transparent background for a shape you can drop onto any page. The Code panel gives the SVG markup to paste into HTML.
Reproducible by design
Every image comes from a seed. The address bar holds the generator, the seed, the size and only the settings you changed, so the link redraws the exact same picture on any device. That is useful for picking up where you left off, sending someone a design, or regenerating a file at a bigger size later. See how it works.
