Hi! nice to hear that you want to make contributions.
I just want to say, (perhaps at the risk of sounding suspiciously like a paid advertiser) if you're looking for a cheap/free vps, oracle cloud is pretty good.
It does require a credit card to sign up, but the "always free" resources are pretty good: 2 micro instances, and a pretty generous usage limit on the ampere instances (enough to run a 4 cpu/24 GB ram instance for a whole month, every month).
I've been using it for a few months to host a blog and a Gitea instance (along with a micro instance acting as an Gitea actions runner). I've heard some stuff about idle instances being reclaimed, but I didn't have much issue so far (though with oracle being oracle I wouldn't be surprised). I guess you could upgrade to a PAYG account to avoid that (you still pay nothing as long as you don't exceed always free resources).
I don't like selling my soul to corporations, but honestly? What oracle cloud gives is a pretty good deal in exchange for my soul :) </shill>
