Products that do what cunoFS – mount S3/AZ/GCP storage *without* FUSE, 60x faster than s3fs does
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://…

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…

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…

Last week SWYX nerd-sniped me into building an Open-source Dropbox. Here is Locker: the ultimate open-source Google Drive/box/Dropbox alternative - Provider agnostic (S3, R2, vercel blob, local) - BYOB (Bring your own bucket) - Virtual file system - QMD Search plugin

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…

This is a long-running project that started as the proverbial need to scratch my own itch and then somehow evolved into a full-time job of the past 6 years. Link: https://bvckup2.com I thought I'd do a Show HN for two reasons. 1. I obviously want to show my baby to those who haven't seen it. Its primary purpose is to do very fast file replication. If you are familiar with "robocopy /mir" - same idea, but on steroids. Lots of them. It can be used for both mirroring and archiving backups, among other things. It is light, very small and it is really quite fast. Half of the…

we've been working on a KV store for the past year or so which is 2-6x faster than Redis (benchmark link below) yet disk persisted! so you get the speed of in-memory KV stores but with disk persistence. To achieve this we've created our custom filesystem that is optimized for our special usecase and we're doing smart batching for writes and predictive fetching for reads. In addition to basic operations, it also provides atomic inc/dec, atomic json patch, range scans and a unique key monitoring mechanism (pub-sub) over WebSockets which essentially allows you to receive notification on…

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.

In my spare time I've been trying to solve the problem of network filesystems being too slow. To that end I've created CacheFS. CacheFS keeps a lazy local copy of your network drive in an attempt to make your network drive appear as fast as your local drive. The project is far from consumer-ready, but it has hit a major milestone: It caches reads and doesn't appear to corrupt anything. I'm throwing it out here in the off-chance that someone else finds it useful, and for constructive feedback. Enjoy! https://github.com/cconstantine/CacheFS
