There are several ways to browse Gemini sites on your computer:

The slickest and easiest solution is to install Lagrange. It's fast, the interface is clean, and it's available for iOS, Flatpak, and a multitude of other platforms. Even better, it also supports the Gopher & Finger protocols. This is useful because a lot of Gemini server operators also run Gopher & Finger servers. Having all three in one visually-pleasing browser is a great way to take in the ecosystem.
