Why is it based of Cloudflare? Can't a different S3 compatible provider/tool be used?
1. Best production ready implementation is probably: https://github.com/lovvtide/satellite-cdn
2. Reference implementation by hzrd194: https://github.com/hzrd149/blossom-server
3. My proof of concept that runs on CloudFlare Free tier for personal use: https://git.v0l.io/florian/cf-worker-blossom-server

1 and 2 should run with any S3 compatible storage. It's not enough to just store the data though - there is also some logic (docker based server) and a database (for ownership, payments..) required. So you need a place to run those as well.
I wanted to build (3) this on serverless components without having to run a docker container and a database anywhere. That's why I implemented that Cloudflare based project and it's APIs are not directly compatible.
This could be done similiarly on AWS mit Lambda Functions, Dynamo DB and S3.
Yeah I understand that it is not just S3. I was just wondering about swapping the object storage layer for Minio or StorJ.
Yeah you can configure your own s3 storage in the config: https://github.com/hzrd149/blossom-server/blob/master/config.example.yml#L37
