One significant caveat: "Free projects are paused after 1 week of inactivity." I'm not complaining, but I reckon a lot of hobby projects would see sporadic activity. For example, I used to upload a list of my CDs to a VPS, so that when I found something interesting at a music store, I could check to see whether I already own it (#FirstWorldProblems).
I think your message implies that performance is the axis that matters and if you don’t need performance at all you should use something other than SQLite (like a file system with json)?
