This "blog post" looks like a couple of tweets, and the code is the same 2 commits (one which added all of the code and a precompiled binary) and one of which adds a license as subspacecloud had 3 months ago.

There are three open pull requests which seem like theyve been completely ignored. Admittedly, one of them says WIP so it's probably reasonable to not merge that.

In the "issues" tab, users are trying to fix issues themselves and getting ignored.

All of the code is attributed to a user (not an organization) named "subspacecloud".

This feels like it's supposed to be a company doing a product announcement, but the actual code seems like a weekend project that has since been neglected. The lack of an actual author is also pretty sketchy
