does infinityfree have lifetime free vps service
Not right now! May be in future if any vendor provide!
We don’t have this, and we won’t have this any time soon.
There is a good reason why there are plenty of free web hosting providers and very few or no free VPS providers: they are very different products and free VPS has a LOT of factors complicating it, such as difficult abuse protection and IP address scarcity.
