Is this project dead?

[Mangatt]

Is anybody mantaining this project? PRs fixing known bugs are not merged for years and issues are not answered.

Is there any viable alternative?

I think so.

The basics seem to work, so I'm planning to use it as a compile target for my new programming language at https://github.com/benrayfield/wikibinator203 As long as its useful, as-is, I wouldnt call it dead. If the basics stopped working, I'd have a reason to try to fix it.
