Platinum - A web browser for humans
Platinum - A web browser for humans
Around the end of 2022, I started an Electron-based browser called Platinum which was a fork of Catalyst. I have spent the last week writing a new browser in Vala using GTK. I am pleased to report that it's now in a usable state.
The GitHub repo is at platinum-browser/platinum-gtk. There is one release.
FAQ:
- Why GTK? It's a well-supported platform that's easy to use.
- Why Vala? Other languages' GTK bindings are often unwieldy. Vala is built for the express purpose of creating GTK apps, making it very easy to do so.
- What OSes does this work on? Theoretically, it should work on any OS if you compile it from source. Currently, automatic release builds are compiled for x86-64 Linux only.
- Aah! My eyes! Is there a dark theme? Themes are being worked on.
- Can you add [insert feature]? Create a PR or issue for it! Although it can be added by maintainers if it's not too much of a hassle. If it's rejected, you'll be able to create a plugin for it at some point.
- Why, exactly, did you make a Scratch forums topic for this, of all things? I wanted to harken back to when the ATs were still alive and when I made the original topic.

catalyst 2.0 real no way… but… why is the new tab button not on the tab barUnfortunately, it's a limitation of GTK's Notebook widget, which I'm using for tabs at the moment

Turns out it was what some may call a “skill issue.” Notebook.set_action_widget lets you add a widget there. The change is in commit d32a4e2.catalyst 2.0 real no way… but… why is the new tab button not on the tab barUnfortunately, it's a limitation of GTK's Notebook widget, which I'm using for tabs at the moment

Oh my god i remember you posting about this on forbidden indigo site. When is the liquid glass theme coming out?Once themes are implemented you can make that yourself. I'm not touching liquid glass with a ten-foot pole.

Yes, although it is not step-by step, only 2 steps, and I tried, yet it is very, very complicated to run all of this.I cannot install it on chromeos, I want a .deb version or a step-by-step instruction on how to install it through the terminal please.There are instructions on the GitHub release page for how to install it on Linux (Or Crostini, probably)
