I used Spine a while back. It&#x27;s such a lovely tool with a great UI, and compatible with Linux.<p>It&#x27;s neither free nor open source though so I don&#x27;t know if this is very suitable here on HN.<p>In any case, I wrote an exporter for Inkscape since they only had an Illustrator plugin for vector graphics:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;jleclanche&#x2F;inkscape-spine-exporter" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;jleclanche&#x2F;inkscape-spine-exporter</a>
