24 alternatives to ZeroFS – A log-structured filesystem for S3

ZeroFS serves S3-compatible buckets as POSIX filesystems over NFS and 9P, or as raw block devices over NBD. Data is compressed and encrypted before upload.

ZeroFS is a log-structured filesystem designed for Amazon S3 cloud storage. It organizes data sequentially to optimize performance and efficiency when storing files in S3. The system is intended for developers and… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

   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…

   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.

   cunoFS – mount S3/AZ/GCP storage *without* FUSE, 60x faster than s3fs▲19

   Hello HN! We’re Dan and Vaughan, based in Cambridge, UK. We recently launched cunoFS, a filesystem for fast, POSIX object storage access. Yes, we’ve heard that “Object Storage is just not suitable for POSIX workloads” or that “workloads should be rewritten to natively support S3”. But what if it could be? And often much faster than S3-native apps? We’ve worked hard to make this possible, without the shortcomings of other approaches. Summary here: - Run (unmodified) applications with S3/AZ/GCP or “S3 compatible” storage, for example: ls s3:// az://…

    Archil's one-click infinite, S3-backed local disks now available▲19

    Hey everyone, I’m Hunter, the founder of Archil. Archil is transforming object storage, like Amazon S3, into infinite, local file systems that provide instant access to massive data sets. Last year, we launched Archil’s NFS-based product publicly on Hacker News (https://news.ycombinator.com/item?id=42174204), and we were absolutely thrilled to see the response of this community. Since our last launch, we took a 10 month company-wide bet to build our own, custom storage protocol to deliver true, local-like performance to cloud instances – by behaving closer to a block storage…

    Turbolite – a SQLite VFS serving sub-250ms cold JOIN queries from S3▲185

    I built a SQLite VFS in Rust that serves cold queries directly from S3 with sub-second performance, and often much faster. It’s called turbolite. It is experimental, buggy, and may corrupt data. I would not trust it with anything important yet. I wanted to explore whether object storage has gotten fast enough to support embedded databases over cloud storage. Filesystems reward tiny random reads and in-place mutation. S3 rewards fewer requests, bigger transfers, immutable objects, and aggressively parallel operations where bandwidth is often the real constraint. This was explicitly inspired…
