I'm currently developing my own native, local-first, cross-platform HN client, a tiny little 7MB built-from-scratch beast: https://i.imgur.com/Y87KJwY.png :)
(Happy to accept beta-testers if people are curious, email above, currently available for Windows, Linux, macOS, iOS and Android, more coming soon! )
