Show HN: A free tool to help design and test procedurally generated NFTs

We were spending hours every day in Photoshop finding files and arranging layers, just to then re-enter those same layers in our generation script. Onion is a tool that cuts all that out:

- Easily select an option for each trait from the preview

- Randomly pick options

- Export created images and metadata

- Generate and export final assets and metadata, with customisable weighting (coming soon)
