I would say for side projects, your best bet is just to make a blog and talk about them, that's what I do anyway [1]. The projects themselves can live wherever, such as a VPS etc. For blog posts these days there are IMO two choices to make:

1. Self publish, I.e. Host the blog yourself. There are many options but I personally go with Hugo/Netlify which uses git and markdown as my "backend" and has the upside of basically being free.

2. Use a publishing service such as Medium or Substack. This is easier, but you have less control over your content that you would self publishing.

Irrespective of this, getting people to read anything you write is the hardest part. You need to share your content, talk to people etc, it takes time.
