Datagrip is a paid, proprietary and closed source commercial product.
True, but it’s one of the strongest offerings out there. Not everything has to be OSS. If you work with SQLite professionally (as I do), spending a few bucks on a good tool shouldn’t be a problem.
I still think SqliteStudio is a phenomenal piece of software. Super lightweight, just works, cross-platform… really not a lot to complain about. And incredibly well maintained.
