I make Beekeeper Studio ( https://beekeeperstudio.io ). This looks really interesting, especially as it is open source. Do you have many FOSS users self-deploying it?
Off topic, but just checked out Beekeeper - Seems like a solid SQL IDE! Had been using Postico before, but going to give yours a try.
And since you don't have analytics, please know that there's at least one person that will use the light theme, please keep it ;)
