1. rustfs

   1 21 28,447 9.9 Rust

   🚀2.3x faster than MinIO for 4KB object payloads. RustFS is an open-source, S3-compatible high-performance object storage system supporting migration and coexistence with other S3-compatible platforms such as MinIO and Ceph.

3. mountpoint-s3

   2 21 5,708 9.5 Rust

   A simple, high-throughput file client for mounting an Amazon S3 bucket as a local file system.

   

   Project mention: S3 Files: The End of Download-Process-Upload (with Terraform) | dev.to | 2026-05-01

   The Lambda benchmark above covers the serverless use case, but it doesn't include Mountpoint for Amazon S3 - AWS's FUSE-based file-system client. Mountpoint is widely used for analytics and ML workloads, so it's a natural comparison. There's just one problem: Mountpoint can't run on Lambda. It's FUSE-based, and Lambda's Firecracker microVM doesn't expose /dev/fuse or grant CAP_SYS_ADMIN - both required for userspace file-system mounts. S3 Files sidesteps this entirely by using NFS, which Lambda natively supports through its existing EFS mount infrastructure.

6. garage

   5 63 3,901 9.5 Rust

   (Mirror) S3-compatible object store for small self-hosted geo-distributed deployments. Main repo: https://git.deuxfleurs.fr/Deuxfleurs/garage

   

   Project mention: From Hermes outputs to a UI for Garage | dev.to | 2026-05-22

   A bit of searching led me to Garage — a self-hosted, S3-compatible object store from Deuxfleurs. Lightweight, replicated, runs happily on a couple of cheap boxes. Exactly the shape I wanted.

7. roapi

   6 27 3,420 6.2 Rust

   Create full-fledged APIs for slowly moving datasets without writing a single line of code.

   

   Project mention: Show HN: Serve CSV Files as APIs | news.ycombinator.com | 2025-06-22

8. tansu

   7 5 1,796 9.7 Rust

   Apache Kafka® compatible broker with S3, PostgreSQL, SQLite, Apache Iceberg and Delta Lake

   

   Project mention: Show HN: Walrus – a Kafka alternative written in Rust | news.ycombinator.com | 2025-12-01

   For Rust-based Kafka alternatives, I like Tansu[1]. It at least provides Kafka API parity, and critically also gives users a pluggable backend (embedded SQLite, S3 for low cost diskless type workloads and Postgres because just use Postgres)

   It’s nice to try and out innovate Kafka, but I fear the network effect can’t be beaten unless the alternative is 10x better.

   Something like Warpstream’s architecture[2] had a shot at dethroning Kafka, but critically even they adopted the Kafka API. Sure enough, Apache Kafka introduced a competing feature[3] within two years of warpstreams launch too.

15. streamhouse

    14 5 64 2.2 Rust

    Open-source event streaming platform built on S3. Kafka-compatible APIs, built-in SQL engine, schema registry — one Rust binary replaces Kafka + ZooKeeper + KSQL. Retention costs pennies, not thousands

    

    Project mention: Show HN: Streamhouse – all-in-one event streaming for startups | news.ycombinator.com | 2026-03-24

    What doesn't work yet: confluent-kafka clients need wire protocol fixes, and I need more soak testing before I'd trust it for massive sustained loads.

    Project mention: Pg_lake: Postgres with Iceberg and data lake access | news.ycombinator.com | 2025-11-04

    Been experimenting with OpenTelemetry->Parquet conversion lately for logs, metrics, and traces. Lots of related projects popping up in this area. It's powerful and cheap.
