My experience with it wasn't so great. Very buggy and unintuitive. I also got summarily dismissed on github when reporting a very pedestrian bug/oversight. https://github.com/TablePlus/TablePlus/issues/677
Aesthetically, it looks great though. I wanted to like it.
TablePlus is very nice and it supports NoSQL databases like Cassandra, CockroachDB, and Redis. It's Electron-based, so it is relatively heavyweight, but I like it a lot.
It is not Electron, it's native. The reason it's heavy because it contains the database drivers, some of them is hundreds of MBs (Oracle > 200MB).
Pardon me - I've checked and you are right. The look&feel really threw me off here, and I could've sworn it's browser-based.
