ankicommunity-sync-server VS zim-desktop-wiki

No need for complex server setup

But if you are still above limits, then there is an open source Anki sync server code. You can run it on your PC and use it instead of Anki Web server: https://github.com/ankicommunity/anki-sync-server

If you have a knowledge of programming, you may use this self host sync server. https://github.com/ankicommunity/anki-sync-server

Question here. I have my Anki collection that I use on several machines (2 pcs and 1 phone). However, I would also like to have offline server for storing some flashcards on professional stuff I don't want shared on Anki servers (that could violate NDA agreements I am bound with). I've done some preliminary research and it seems like https://github.com/ankicommunity/anki-sync-server could be used for creating private Anki server. However I'm not sure how to set it up properly so it won't interfere with my AnkiWeb setup. My guesses are either:

It already exists: https://github.com/ankicommunity/anki-sync-server

Unfortunately, I reached this limit (with almost 1,8 million reviews and a couple hundred thousand cards), and Git Hub's alternative sync server seems not to work with IOS App. I'd willing to pay for more space, if I had this option.

Yes, maybe the Anki developers wouldn't want to provide syncing for someone that is just using AnkiDroid everywhere, but solutions like this exist: https://github.com/ankicommunity/anki-sync-server

I'll slightly modify your argument; because Pure HTML does suck:

Why don't people make static sites with a simple "Markdown-or-Similar to HTML" converter, CSS, and vanilla JS...etc?

(This is what I do, btw -- http://zim-wiki.org + a template)

You should add Zim [1] to the "Personal Knowledge Management" section :)

And I just tweaked the CSS and added a bit of logic to included the possibility of one image per slide; as well as editing slides not with raw HTML but with https://zim-wiki.org (because that's what I'm really used to, I'm sure any Markdown thing would work just as well).

Absolutely; recently I realize I wish I'd never learned vim. I use too many other programs that are at least CUA-ish ( http://zim-wiki.org is the most important app I use ) and now I kind of want out. I haven't yet tried Modeless Vim, but that looks like my next experiment.

It is so hard not to feel REALLY SMUG reading stuff like this, as someone who has run my own website as the working primary source for my college instruction for the past 15 years or so using https://zim-wiki.org. (before Markdown was much of a thing!)

It's borderline bizarre to have watched this method of doing things kind of die out, and then also come back in the form of "static site generators" -- which, frankly, are still way clunkier than this.

Write in Zim, export to html, rsync to site. Easy.
