Probably not, sandstorm is abandoned, most softwares are broken and unmaintained, gitlab version is from 2016 and full of vulnerabilities, same for WordPress version from 2018.
Project is dead. I think the guy behind the project was hired by Cloudflare few years ago
I know that there was some work on reviving sandstorm after Kenton Varda joined Cloudflare, see e.g. https://sandstorm.io/news/2020-02-03-reviving-sandstorm, but it is very possible it never got anywhere. Sad but understandable.
