I think the UI code is not open source (so you can't build the browser yourself).

To be honest, I don't think I buy this. I'm from NZ and we have a number of introduced species (possums, stoats) which have a dramatic impact on the native wildlife.

A lot of bird species in NZ are unique and only found here. They're almost all critically endangered or at risk [1], as they evolved with no natural predators.

I'd rather we try and control these introduced species so we can keep (at least some of) our native birds.

Perhaps you should fight fire with fire - export NZ native wildlife around the world and hopefully it'll become invasive and flourish somewhere else! It worked well enough for Australia [1]!

(I shouldn't need to say this, but this is a joke and should not be taken as environmental policy :) )

> this is a joke

it is reality in most.of the world. Humans turned the ecosystem in a world of invasive species.

Brave is definitely open source [1] (under the MPL)? The source for Safari is closed, but their rendering engine is completely open source [2].

Yeah, you can do something like that with a ServiceWorker - it does require some JavaScript though.

I use webpack for compiling the Typescript but everything else is from scratch.

I made https://readr.nz/ which works pretty well for me. Source code is here https://github.com/fallaciousreasoning/progrssive

I wrote a PWA for reading RSS feeds. It works fully offline and should be installable in Chromium based browsers (I develop in Firefox, but Chromium definitely has better PWA support).

Cool project! I completely agree, it's my go to playground for tryi g out new ideas.

Mine is here: https://github.com/fallaciousreasoning/progrssive

I wrote https://github.com/fallaciousreasoning/progrssive for this reason(and for offline support). It's free, and should be trivial to selfhost (there's also a live version at https://readr.nz)
