What's wrong with MS Word/OpenOffice/LibreOffice? You might need an updated CV every couple of years and who knows if other web-based tools still exist then.
I've never enjoyed making my CVs in a text-processor. Maybe I have the wrong idea of a CV, but I'd like it to be somewhat pretty and also maintainable. I really wish that jsonresume.org takes off and to finally have one standard that works everywhere. Whether a web app dies or not.
Learned this from a friend of mine. Build it in HTML, and have a nice looking display stylesheet that you can email to people who might appreciate such a thing, and also have a print stylesheet which you then print to PDF from your browser of choice.
Looking forward to getting rid of my latex version soon.
Well I was just checking this post about markdown-based resume tool... played with it a little and looked nice for me, may help https://github.com/awalGarg/cv-maker/
