I very often use VPS as a playground of sorts to develop small web apps and don’t want to have to worry about recurring billing or someone using one of those machines to collect data on me. I have tried multiple anonymous VPS providers and the best one I’ve used so far has to be hivecloud.pw. You pay for your server with either perfect money or crypto and it gets deployed within 20 minutes. I’ve never had any problems with outages or the wrong machine being delivered. If you’re looking for a relatively cheap VPS just for testing or anything temporary I couldn’t recommend them enough.
