I'm a big fan of svg-term myself: https://github.com/marionebl/svg-term-cli

Hm, very interesting! This only converts asciinema recordings, though, right? It doesn't automatically record anything?

If you have asciinema already installed then you can invoke it through svg-term like this!

  svg-term --command 'cowsay hey there'

But that has the aforementioned issues about not pausing enough, so I usually just record with asciinema first and then invoke svg-term.
