@mirlo I can offer you some free hosting. The major draw backs are (a) I’m in the US, so that puts some people off, and (b) my uptime is about 99%. Nothing like the 3-5 nines you get at commercial hosting.
It’s fairly beefy, on-prem in my house behind a business-grade (not residential) DSL line. The advantages are that I won’t ask for any money and I will give you a VM beefier than you’re likely to get at a hosting provider. (4-8 cores, 8-16G ram, hundreds of gigs of disk). Let me know if you are interested. I want to support projects like yours.
