As usual the industry safes money and the customer has to pay for the memory. I’m sick of applications which doesn’t adapt to HiDPI (automatically) and consume 500 MB of memory whereas a C/C++, Rust or even Python with Gtk or Qt will consume about 50 MB.
Aside from that Postman has become unusable because the company behind it want to earn „now“ money. I don’t say HTTPies UI is bad it just not what users want.

It's a trade-off.
Without Electron and the likes, a fraction of the apps that are now almost effortlessly cross-platform would exist for Linux, for example.
Then HTML became that common subset of the UI and the browser JS runtime and rendering engine replaced the cross platform toolkit. Bloated, not optimized for space and time as it could be, etc, but very convenient.
Kreya isn't based on Electron, but uses the native WebView of the OS.
