This is not really a valid criticism for an Open Source project. I built Ladybird from source yesterday and I am typing this comment in it now. So, I assure you that the Ladybird browser exists.

Of course, Ladybird is not production ready yet. Feature-wise, it is getting close. I can use it to do most of the things I want to do with a browser. Speed and reliability are another matter. I has gotten dramatically faster but normal users would still find it slow. But the biggest problem is reliability. I would not use it in its current form for anything that matters.

But for a complicated application that was started from scratch, not being ready yet is not an indictment. They claim it will be ready for regular users to try sometime this year and, from where I type, this seems realistic.
