NixOS. My primary reason for switching was wanting a single list of programs that I had installed. After using ubuntu for 5 years I just lost track of all the tools and versions of software that I had installed…and that didnt even count my laptop. Now all my machines have a single list of applications, and they are all in sync.

Yeah, you’re totally right.

All image processing happens locally.

And then it mentions that you can just open the index.html directly, which means it uses clientside javascript or wasm and runs on the browser. You are correct!

On the topic of word choice, you might be right. Save or open might be better.

Just because its run locally, doesnt mean it still isnt a web server. The software could run anywhere and be accessed over the network. The image optimization happens at the server, so download and upload are more accurate.
