Not that offer s3-compatible object storage (which I guess is on the roadmap) and Turin VPS. These prices are legit and I'm not pulling the trigger yet but I'm definitely interested.
Someone on lowendtalk recently created a very minimalist php s3 thing too if you only need the basic crud app but I would recommend you to select garage from what I've heard
I have also heard someone creating a new rust s3 application but I forgot its name but maybe you can look out for it too and see what fits the best for your goal.
Also coolify team is maintaining a docker image of MinIO but that was before they said that minio is going closed source and that they had just stopped providing docker images so I am not sure how valid it is right now. There must be forks who are maintaining Minio too so you can look at it too.
