   CallFS – S3-style object store in one Go binary (MIT)▲66

   We started CallFS after yet another late-night “why did the uploads vanish?” incident. Our small team had stitched together rsync, a fragile NFS mount, and an S3 bucket—none of it observable, all of it waiting to bite us. So we wrote a single-process file service in Go that: • Speaks the S3 API (so existing tooling works). • Stores hot data on local disks for speed; cold data can sit in any S3-compatible bucket. • Exposes Prometheus metrics and JSON logs by default, because “what happened?” shouldn’t be guesswork. • Ships as a ~25 MB static binary—no external deps, MIT license. Today it’s…

    Low-cost backup to S3 Glacier Deep Archive▲120

    Hi, most people (hopefully) have local backups. However, when that backup fails, it is good to have a backup stored somewhere off-site. In the old days you would ship physical drives/tapes, which is cumbersome, costly, and slow. With fast upload speeds, it is now possible to upload your data to the cloud. I have found S3 Glacier Deep Archive to be a great solution for this: - It is very cheap ($1/TB/month for US region) - Very reliable (99.999999999% data durability, data spread over 3 Availability Zones) However, usability out of the box is not that great, I'm not aware of…

    Zs3 – S3 server in ~1K lines of Zig, 250KB binary, zero dependencies▲42

    Most S3 usage is PUT, GET, DELETE, LIST with basic auth. This does exactly that. SigV4 auth, multipart uploads, range requests. Storage is just files on disk. No versioning, no ACLs, no encryption. Use MinIO or AWS if you need those.

    RemoteStorage – sync localStorage across devices and browsers▲129

    Hey HN! Wanted to share a new library and server I've recently been working on called remoteStorage. When building frontends with Javascript, the native localStorage API is super useful for keeping track of state between sessions in the same browser, but it's not as good a solution when your data needs to be shared across multiple devices or browsers. For instance, let's say you want to show a welcome modal to all new users that sign up for your product. If you use localStorage to track if a user has already seen this modal, your users will end up getting the experience repeatedly every time…
