How does this compare with https://sqlitebrowser.org/ ?

I've used both. Sqlitestudio is far more powerful, intuitive and easy to use. Fast and efficient. Flies even in old PCs. In Linux you won't find It in the repositories. You have to download and run a handy installer.

That's my Swiss knife.

Super handy in a lot of scenarios, and I use it side-by-side with Jetbrains' DataGrip.

I have been using sqlitebrowser as well. Fairly satisfied, except for the poor 'export to csv' that seems to fail on respecting csv separations in some cases. Does SQLiteStudio handle this correctly?

My goto as well.
