It's kind of hard for me to think of a devtool as local-first or not, since the actual definition of local-first [1] talks about end-user software, not devtools.

So the question is whether it's possible to build software that adheres to the local-first principles using sqlite-sync.

edit: I'm aware people are using the term "local-first" very loosely, so perhaps my reply here is a bit off-topic

p.s. yes you can self-host ElectricSQL

p.p.s. I really need to keep my list of "sqlite sync" things updated: I have SQLSync [2], SQLiteSync [3] and now SQLite-Sync [4]. Simple!
