Shapes fired on your machine.
OG images, mesh gradients, grain, waves, and blobs — five generators that render everything in your browser. No uploads, no accounts, no watermarks. Shuffle until it looks right, then take the file.

Why local-only generators
Every tool on this site is plain JavaScript running in your tab: the geometry, the randomness, the preview, and the file you download. That means there is nothing to sign up for, no queue, no watermark, and no server looking at your work — a headline you type into the OG generator or a logo you drop on it never leaves your machine. It also means the tools are fast (there's no round trip) and keep working when your connection doesn't.
ShapeKiln is the third of the Kiln utilities, after FileKiln (file converters) and GradeKiln (GPA calculators) — same principle each time: the work happens in your browser, and your files are nobody's business but yours.
