I have done little Wordpress development (just some plugin for a prototype that my company wanted). But I don't see anything that prevented it from being used to develop a web application since the theme/plugin system seems to fulfill everything. Django also describes itself as a CMS platform on their website so I kind of thought they are comparable.
Just wanted to make sure I know what I'm getting before I jumps in further into either Wordpress or Django :D
Wordpress is technically capable of being used to build large apps, but, you're going to be rolling your own everything. Whereas a framework, is, well, a framework that has standardized and cleanly extensible ways of doing core functionalities X, Y, and Z.
Wordpress is old, and they've built up a shit-ton of technical debt for the sake of BC. To put it bluntly, it's not a pleasure to work with, at all. On the up side, something like 20% of the surface net runs on Wordpress. There's a huge market for WP skills, and it's got enormous mindshare amongst non-technical types. If you want to invest effort in WP, do it because of the adoption metrics; if you're more technically oriented, pick Django (or Laravel/Symfony if PHP is more your speed).
Well, wordpress is a cms that, through custom work, can be used as a web framework (ie you can built other, non-cms, things with it). Django is a web framework that can be used to build a cms.
Actually there are some great cms built on top of django, for example django-cms or wagtail!
If you start from scratch and want to build a simple cms it will be easier to do it with wp, if ofcourse you tolerate php - some people won't use php for reasons that should be well known to hn readers. However, for any other web development I recommed using django (or another normal web framework).
Using wp to build non-cms stuff reminds me the "when your only tool is a hammer everything looks like a nail" argument! You may use your hammer to cut (break) wood but using your saw would be easier and safer!
I've seen that line of thinking with newer devs who don't understand the right tool for the job. Unless your client specifically wants a custom solution for a custom purpose, you will spend the first week writing a CMS in Django and the next 20 recreating .1% of WP's functionality because you didn't anticipate the full list of client's needs correctly.
If you're tied to wordpress, I'd take a look at laravel it's built in php, has the largest community as far as PHP frameworks go, and you can literally build anything, and incorporate packages from packagist, etc... Wordpress is slow, has a HUGE codebase and you can't really control it as granularly as you can a fresh laravel app.
Or am i wrong?
PS... Django <3
