Our own code
The tool engine (normal and height maps, PBR maps, filters, tiling, packing, the 3D preview) and the page layouts are written for this site. The pages make no requests to other servers.
Open-source libraries
These libraries run inside the tools, unmodified or only bundled and minified. Each is used under its licence, and its licence file ships with the site’s code.
