WordPress's core APIs might be very well-supported, but most of their plugin ecosystem doesn't have such guarantees.

I recently tried to revive a 2014 backup of my local hackerspace's website so that I could staticize it, but it wouldn't look right even with the same PHP and MySQL versions, because many of the plugins stopped working.

I think I would have been better off scraping a copy of the site from Archive.org.

Yes. Many plugs will retire, but most mainstream plugins should work or easy to find replacement. A personal website / blog without too many customizations should be easy to revive.

A static site generator that works now will probably still work in 10 years, even if updates cease. And it will be safe to use. After all, it just churns out HTML that you put somewhere.

The same can't be said of WordPress or MediaWiki. You will not be able to run these at all if they become unsupported and will have to migrate, or risk facing security issues.

Sure, SSGs are not for everyone, but the potential for deprecation isn't a major issue, at least for a personal site.

I pay for hosting and Wordpress, is super cheap, I wrote soem blog posts in 2-13 then got bored, the site is still up and is up to date, with no effort from me, no code or sysadmining about. If I need I can start blogging again tomorrow from a browser or I could get a fancy app but if you used some non-standard thing you need to keep admining it, and if you maybe stopped like me for 8 years when you get back you probably forgot all the details about what stuff you used.

If for some reason all those companies selling and supporting Wordpress would not be allowed to continue using it by magic I am sure they are capable enough to migrate it for me.

My only experience with Wordpress is with a simple blog and not complex sales pages or other stuff that require using SEO/sales/magic plugins. Worst case scenario if you are a developer you can dump the wordpress database into a file then write a script and generate plain html files or migrate to some other format.

Wordpress has export function. I am almost 100% sure, if Wordpress dies its replacement will be able to import Wordpress exports, or even its database.

I've recently upgraded a MediaWiki website (colemak.com) to the latest version from version 1.5.3 (released Dec/2005).

Besides a few minor configuration updates, it worked almost out of the box after the upgrade on a new server.

Limiting edit access to a handful of trusted users and keeping the server patched was enough to keep it from being hacked.

Thanks! Really good to know. I have being struggling with choosing between Wordpress and MediaWiki for a side project.

None of the popular static site generators match Wordpress or Mediawiki for how long they've been around. Although for me personally, the established ones are old and popular enough. E.g., I use Pelican, which has been around since 2010.

Jekyll is almost as old as Wordpress.

2003 vs 2008

I have never used Jekyll, so I Googled jekyll backward compatibility and I found several breaking changes.

Also I realized another issue with SSG, the setup is on the desktop, not on the server. I have problems with this too.
