Blobs
Up to 24 colour points. Every blob colours its local area in every style. Drag blobs on the canvas. Click one to change its colour. Double-click one to remove it.
Blend
Sweep uses the first four blob colours as field, band, lobe and corner glow. Fold X/Y moves the tip, Silk fold bends the lobe, Swirl tilts the band and Softness softens its edges. Extra blobs add local colour accents.
Flow uses one continuous S-shaped body. Drag the blue and violet blobs to bend its upper and lower halves; magenta and cyan move the surrounding surfaces. Fold X/Y moves the composition, Silk fold deepens the cyan cut-in, Swirl tilts the shapes and Softness changes their edges. Edge fade blends into the background.

Your gradient
Choose a shape above. The canvas changes with it, and the PNG keeps that same framing without the control points. Custom size lets you set any ratio.
Why I built this
I often need a background in Illustrator or Photoshop, and my client usually has a colour theme. A gradient in that exact theme is hard to find, and what I download from Google rarely feels right. So I built Gradient Lab. I add the colours my client needs, give them effects like a swirl, and download the result. It can even get close to the gradient style Apple uses.
