   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…

    SandCrab▲152

    Hello HN. SandCrab is an app I originally had the idea for and hacked together over a couple of weekends last October. More recently, I’ve been working on adding new features to it as I use it more as my daily tool to interact with my s3 buckets. A few recent features I am excited about include the ability to search across all of your buckets using wildcards and regular expressions as well as searching and filtering by metadata (e.g. content type, file size, date created, etc). I’ve also added support for configuring and generating presigned urls directly in the app which is nice. The app…
