Coolify unfortunately didn't click with me, and I had a bad experience with a Redis database, so I stopped using it.
I would recommend Elestio (eles[dot]io) as an alternative which isn't open source, or self-hostable, but met my primary goal of drastically reducing cloud costs. And you can bring your own cloud/server, though I'm choosing to also rent from Hetzner through Elestio.
I'm running two redis databases on machines with 3 cpus, 4gb ram, and 80gb storage for about $80 total (the machines are billed hourly, but you get the max monthly bill up front).
I tried this with rokid max: it was not usable for me, as it was too blurry. likely reason was my IPD (I think 71). You may read that this device can adjust IPD, but it's a software solution, not hardware. since I had no compatible mobile device (no current enough android version), I could not even test this.
