Depends on whether AGPL v3 works for you or not (or whether you decide to pay them), I guess: https://min.io/pricing
I've actually been looking for more open alternatives, but haven't found much.
Zenko CloudServer seemed to be somewhat promising, but doesn't seem to be managed very actively: https://github.com/scality/cloudserver/issues/4986 (their Docker images on DockerHub were last updated 10 months ago, which is what the homepage links to; blog doesn't seem active since 2019, forums don't have much going on, despite some action on GitHub still)
There was also Garage, but that one is also AGPL v3: https://garagehq.deuxfleurs.fr/
The closest I got was discovering that SeaweedFS has an S3 compatible mode: https://github.com/seaweedfs/seaweedfs
