This is made using a static site generator.
According to wikipedia, it's software that turns markdown files into webpages. I use zola, but there are more than a few that get the job done.
A static website, as opposed to a dynamic website, will always load the same way every time. There's no trackers or anything to change what you see based on your history, location, etc. They also load very quickly, since there's so little to render.
You create markdown files.
The SSG uses templates to parse how to layout the website.
You push any changes and a fresh build of your website is made.
The site is deployed and can be visited by anyone.
Obviously, slightly more complicated than that but you get the gist. I'll write up a how-to on how I accomplished this myself. If it's 2027 and you're still seeing this, feel free to yell at me.
It's a common, simple markup language for formatting text. It's more involved than using a regular text editor, but is a lot less work than coding it yourself.
Faster load times! There's almost nothing to process, so the pages just load almost instantly.
It's free (if you want). I don't pay for hosting. I'm using codeberg.org to manage that for me. Part of the "cost" is that my code is available for anyone to view, but I don't have to pay a cent. It takes so little to host these kinds of websites, it's not a big deal. Some hosts charge, but I don't see the benefit.
Scalability. From an infrustructure point of view, that means you can have hundreds of thousands of visitors without an issue. There won't be a shock value when you hit some unexpected server load because you popped off and got noticed by everyone.
You can still have things like comments, an RSS feed, and more. It's well catered to blogs, but you can still use an SSG for things like landing pages, portfolios, documentation, and more.
I'll be honest, I don't know or care. Supposedly, yes but I'm so far removed from how that works. Instead, I'd rather use word of mouth and webrings.
