24 alternatives to Zs3 – S3 server in ~1K lines of Zig, 250KB binary, zero dependencies
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.
Zs3 is a lightweight S3-compatible server written in Zig that handles core operations like file upload, download, deletion, and listing with SigV4 authentication. It supports multipart uploads and range requests… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

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.

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…

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…

Hi HN, I'm Emilie, I have a literature background (which explains the well-written documentation!) and I've been learning Rust and distributed systems by building minikv over the past few months. It recently got featured in Programmez! magazine: https://www.programmez.com/actualites/minikv-un-key-value-st... minikv is an open-source, distributed storage engine built for learning, experimentation, and self-hosted setups. It combines a strongly-consistent key-value database (Raft), S3-compatible object storage, and basic multi-tenancy. Features/highlights: - Raft…

This is a MVP for Serverless Postgres. 1/ It uses Fly.io[0], which can automatically pause your database after all connections are released (and start it again when new connections join). 2/ It uses Oriole[1], a Postgres extension with experimental support for S3 / Decoupled Storage[2]. 3/ It uses Tigris[3], Globally Distributed S3-Compatible Object Storage. Oriole will automatically backup the data to Tigris using background workers. I wouldn't recommend using this in production, but I think it's in a good spot to provoke some discussion and ideas. You can get it running…

Hey HN, AWS S3 Express One Zone promises improved latency and throughput but comes with several limitations including only being available in one availability zone and the directory bucket structure. We developed Accelerated Cloud Storage to offer an object storage system with high performance (up to 10X better than S3 Express One Zone in latency and throughput), strong consistency and global availability that scales and moves data based on demand. The service is accessible through an S3 compatible Go/Python SDK. ACS has enterprise-grade security compliance (SOC 2 Type 2 pending), and a…
