Show HN: Shoebox – S3 API for your local filesystem (opens in new tab)

I have 2TB of photos across a 6-drive btrfs array. External drives from 2004, NextCloud phone backups, scanned photos from the 80s. Some files duplicated 3 times across forgotten folders. Finding duplicates was always a weekend project that never happened.

Then I realized: if an object store knows every file's content hash, duplicates are just a GROUP BY.

Built a tool that serves local files via S3 API:

    docker run -it -v ~/Photos:/data -p 9000:9000 ghcr.io/deepjoy/shoebox /data

Credentials auto-generated and printed on startup. Works with rclone, AWS CLI, any S3 SDK. Files stay exactly where they are.

The duplicate detection I wanted is one query. But the real surprise: every S3 tool just works. I set out to find duplicate photos and accidentally built a local S3 server.

What it is: S3-compatible object store for local filesystems. Rust, axum, SQLite for metadata. MIT licensed. Or build from source with `cargo install`.

What it isn't: not distributed, not for petabyte scale, not a MinIO replacement. MinIO is built for production clusters. This is built for the NAS in your closet. Single node, single process. If you need multi-machine replication, use MinIO or SeaweedFS.

Tested on real hardware this past week. A few early users ran it against their own NAS setups on btrfs, ext4, and ZFS. Built a companion webapp to browse duplicates visually (duplicate detection is non-standard S3, so terminal demos weren't compelling).
