Why SVG (and Snap)?
Modern features for modern browsers
Snap.svg is designed for modern browsers and therefore supports the newest SVG features like masking, clipping, patterns, full gradients, groups, and more.
Of course you can generate SVG with Snap, but you can also use Snap to work with SVG generated from tools like Adobe Illustrator, Inkscape, or Sketch. You can even load strings of SVG asynchronously and query out the pieces you need in order to turn SVG files into sprite sheets.
Open-source and free
Snap.svg is available under an Apache 2 license which means it’s completely open-source, and completely free.
