alt Hacker NewsFlutter / Dart? It's compiled ahead of time and doesn't use an embedded browser so I'd expect it to be a lot lighter, though I haven't measured.
But the general lack of really cross-platform (desktop + mobile + maybe web) ecosystems is just as much as sign that devs consider multi-gigabyte Electron apps "good enough" as the apps themselves.
>at devs consider multi-gigabyte Electron apps "good enough" as the apps themselves.
This kind of misses out on a hierarchy of devs here and the amount of work to make it happen. Electron took a large chunk from a multi-billion dollar endeavor to use to make all this work. Electron only worked because Chrome was there. Chrome worked because Google already had unlimited money from advertising, and getting advertising on every device possible was their goal.
Devs might want light apps everywhere, but seemingly none are going to dedicate the rest of their life and money to make it work.
