The author made a ShowHN post (https://news.ycombinator.com/item?id=8683597) about this previously, where they commented (https://news.ycombinator.com/item?id=8684082) that he had no plans for a Windows or Linux port - but they wouldn't mind if someone else used the same design and format to do so.

There seems to be a lot of similar interest, so maybe someone with the right skills could start a community developed open source linux and/or windows port.
