A few days ago I read an article about the ability to test Nginx configs online. In your browser! I use Caddy these days but there are still some "old" Nginx servers running so I need to change them from time to time. While Caddy has a super easy setup that's not true for Nginx. Online Nginx config generator from Digital Ocean is a great help but to test the config and experiment while tuning it for a specific application is even better. But that's not all. There are more similar playgrounds in the article, so I decided to pin them here for my future self. Feel free to suggest some if you know more.
