FYI, it is kind of ridiculous that you support all these RDBMS but it doesn't mention anything other than DuckDB on the landing page. Your GitHub README is infinitely more useful. You should probably fix that, because the LP gives a very incorrect impression of the capabilities and features of your product!
Edit: just tried it on Windows and you have mojibaked text on the welcome dialog [0].
Edit 2: Unfortunately your product has some architectural/design issues. Way too much latency, UI hangs a lot simply following the action links in the welcome dialog, trying to open a 3 mib database hung the software until I killed it, etc. The interface is highly non-idiomatic and doesn't follow ui patterns common to any of the major desktops (in response to keyboard shortcuts, mouse operations, etc), and doesn't do a lot of what I would consider to be basic safety/sanity checks (i.e. tries to open a binary database as a text sql file, shows garbled unicode).
