Layer Generator
Stack trait layers into up to 10,000 unique pieces with weighted rarity, trait rules and Metaplex metadata — rendered right here in your browser, then straight into a launch.
Step 01 — bring your art
Drop your
layers folder.
One folder per layer, one transparent image per trait. Drop it anywhere in this box — or pick one of the three ways below. Everything stays in your browser.
- AImport a whole folder
Every subfolder becomes a layer. Drag it here, or choose it. A .zip of the folder works too.
- BBuild it layer by layer
Add a layer, name it, drop in just that layer's images. Repeat for the next one.
- CTry demo layers
A generated 4-layer set so you can explore every feature first.
PNG · JPG · WEBP · GIF · AVIF — same size images with transparent backgrounds work best.

- 1_
- Layer order. 1 is drawn first (the back); higher numbers go on top. Reorder any time later.
- #20
- Rarity weight. Higher = more common. No #? It defaults to 10.
- none
- A None/blank image lets that layer be empty on some pieces.
