Developer Diary is a Gatsby Starter blog template created with web developers in mind, but really, anyone can use it. It's totally usable right out of the box, but minimalist enough to be easily modifiable to suit your needs.
Blazing fast, as you'd expect from a Gatsby site
Includes Prism for code block styling in markdown files
Developer-relevant social-media icon links including GitHub, Stack Overflow and freeCodeCamp
Mobile responsive, of course
