Is the Vivaldi Browser Open Source or Not?
There's so many Chromium clones out there.
Many of them claim to be somehow more privacy-respecting than Google Chrome, and more open sourced.
A lot of unsubstantiated rumours are floating around, and official explanations (on the browser's website) are usually deliberately vague.
Fortunately, one of the main Vivaldi developers was happy to discuss & answer questions on LQ, and here's a little excerpt:
the new Opera is yet another chromium clone - there's been a rift a while back.
while Vivaldi indeed claims to be based on the old Opera, it is now closed source. Just saying.
imho there are much better alternatives for gnu/linux, a free and open source operating system.
some distros still ship the old opera in their repositories, please check that out.
@ondoho the old opera is also closed source. Just saying
As it happens, all of the code changes that Vivaldi makes to upstream chromium are open source and can be downloaded from https://vivaldi.com/source/
Only the Vivaldi UI (written in HTML/JS/CSS) is proprietary. However, given that these languages are not compiled the source is at least viewable. The new Opera on the other hand is has closed C++ parts, whose source cannot be checked.
Also we (Vivaldi, my employer) do not claim to be based on the old Opera. The only claim we make is that we follow many of the concepts of the old Opera and that we employee several ex-opera employees, including several long term members of the old desktop team.
sorry for missing that vivaldi is based on chromium, too.
that of course invalidates a part of my argument, because chromium is open source.
however, there must be something in the claim of vivaldi not being fully open source.
see vivaldi forums search results:
this thread sticks out:
people discuss it for 4 years, and never once do the devs come out and commit to vivaldi being open source.
no, only 4 months ago we hear that some of it is. clearly at that point the marketing department said: "open source is a term that makes people feel good. we want to ride that train, but not really commit to it"
every news article i find about vivaldi uses the term open source , but never once commits to it:
"many big projects in the open source world",
"powered by libraries from more than 100 different open source projects" and so on.
look, there's nothing wrong with it.
you have a product, and while you're not selling it, you still see some financial gain and want to further & protect that.
but there's so many good & truly open source browsers for an open source operating system.
people often just assume that everything in the linux world is open source, and i like to at least make them aware of the difference.
i think you can see how many people would have misinterpreted that "story".
in fact, there isn't really much left in the "story" after you demystified it for us. thank you.
