This is the kind of project where the death of “native” as a term is sad.

You’re not truly native if you’re using egui, you’re just a step above Electron & co. TablePlus is actually native and it shows.

If you’re vibe coding this shit, why can’t you just tell it to output platform specific things?

It's native in that it doesn't start a whole web browser with hooks to native code, like most cross-platform applications. That saves a lot of RAM and storage (unless you're willing to subject yourself to testing with each platform's web view, which brings its own problems to the table for minimal benefit).

Based on the description, it looks like the author is using Linux. Native doesn't really exist there. There are a couple of flavours, but none of them are any more native than the other, and none of them are much more native than just rendering the UI yourself.

Modern Windows and Android development also often use the very same technique. Old Win32 (and I presume macOS, though the rise of iPad apps on macOS make me start to wonder) still offer some native-ish controls but they're not usable outside of their own platforms.

With egui you don't need to actually run a full copy of every version of Windows and macOS to see if the program runs. If it compiles, it'll work.

I wouldn't say it's just a step above electron, I think the term "native" has always been a little overloaded in this way. For example, a game that uses egui for the HuD/menus could be rightly called native compared to a web game.

You're talking about "native controls", which is more specific. That said, I don't see any reason why egui would be used over native controls for this type of app. They probably just didn't think to ask their AI.

I imagine with AI, something like libui-ng would be pretty easy to improve and maintain. Looks like development has stalled though.
