Install DBeaver SQLite driver offline?
DBeaver supports any database that has a JDBC driver. So, the best thing to do is to go to the SQLite people themselves - they have a list of such drivers here. The page itself is quite old, so don't worry about the dates - just check around and see which one best suits your needs/is supported. Just as a matter of interest, SQuirreL SQL also works via JDBC - it's pure Java and is, IHMO, more mature than DBeaver, but YMMV.
