Show HN: PostgreSQL running in the browser, persisting to S3

Score: 8.3/10 (Innovation: 8, Technical: 9, Documentation: 9, Utility: 7)

ZeroFS is a filesystem and block device server that makes S3-compatible storage behave like a local POSIX filesystem, accessible via NFS, 9P, and NBD protocols. It's technically impressive for enabling complex workloads like running ZFS, compiling the Linux kernel, or even booting Ubuntu directly from object storage, all with encryption, compression, and a web UI. This project is interesting because it fundamentally rethinks cloud storage architecture, allowing databases and traditional filesystems to use S3 as primary storage without modification.

Target audience: devops, backend devs, data engineers
