Names from various Final Fantasy titles. Playable character names for workstations. Names of summons for servers. Names of cities and locations for networking devices. Names of Moogles for some services that I wanted to give a unique name.
I generally like to take a whole “universe” for naming schemes. Star Trek is another favoured one, since you get a variety of names in different categories. Characters, Ships, Places, etc.
I often recommend people using the “100 searches” trial of kagi to see if it might be worth it for them. I tried it and for me the price is worth it because of the custom filters and weights for results. It’s really nice to search for something and all results on the first page are relevant content (no ads, seo-bait pages or stuff like Pinterest).
