- It is cumbersome to distribute. Rarely people have PHP installed outside of a docker container, and given quite short development lifecycle chances are their version of PHP is already outdated.
- Concurrency support in PHP is still very poor. That seems quite a big deal for a desktop app.
- NativePHP is anything but native. It relies on Electron, which is somewhat questionable on its own (even though very common nowadays).
- …And, since it pretty much is just Electron, why do I need a Laravel app underneath anyway?! If there is a job for JS, it's exactly programming UIs (primarily because there are millions of UIs and thousands UI-targeted libraries written in JS by now)
So, I am very skeptical.
