FWIW, asciinema is something that&#x27;s been posted and discussed before...what&#x27;s new is that the player can be self-hosted, as it consists of nothing more than a JS and CSS file. This means the recording can be exported as a flat JSON file. Previously, the only option was to host the replay on the asciinema server: <a href="http:&#x2F;&#x2F;blog.asciinema.org&#x2F;post&#x2F;self-hosting&#x2F;" rel="nofollow">http:&#x2F;&#x2F;blog.asciinema.org&#x2F;post&#x2F;self-hosting&#x2F;</a><p>As someone who writes a few tutorials on programming...this is a godsend. Novices need to be able to see how the code works interactively...but it&#x27;s a real pain in the ass to render animated GIFs. Asciinema creates something that is lightweight and just text, for all the flexibility and portability that allows.
