One of the most significant banes of my existence has been the lack of proper webcomic CMS options available. See if you look for anything webcomic self-hosting related, most services direct you to the most available and common, Comic Press. A Wordpress Plugin.
http://comicpress.net/It's not bad by any means I just have a great disdain for WordPress and I don't need something THAT big or powerful for a webcomic, I can make the rest of the site myself, I JUST need an engine for the webcomic.
There have been CMS options that have come and gone over the years, many of them were barebones and died because they were insecure and their developers couldn't keep up with the security patches. So there's never been any clear winner for a Comic CMS in my eyes. Even now in 2020, there are very few options and I'll list the few I've found.
https://www.webcomicx.com/This one actually seems pretty nice but it uses ASP.net which means you'd have to have a Windows server in order to run it which, I don't have. Great if you have a windows server tho!
http://www.clickthulu.com/Was looking through this and it seems nice enough Buuut it's 100$ a year for a license. Which I sincerely, do not have and I don't even know if the features are ones that work for me without using it myself. I'm not opposed to a paid CMS but I need to know more about what I'm paying for.
http://ptyxis.cthonic.com/This one seems to be the most reasonable contender, I just need to install it and use it for myself and hope there isn't any vulnerabilities.
http://www.comicctrl.com/The makers for HiveWorks is going to release a to the public version of their webcomic CMS! Cool! except their last update was September 2019 :/ This is one of those services I'd be more amicable to pay for as it's got a tried and true service used by most of the Hive Works comic artists they just need to release it first!!
Why must webcomic hosting try me so.
