SeaweedFS: 4.29 supports cluster-wide atomic S3 conditional writes (If-Match / If-None-Match / ...) with O(1) network roundtrip, without a costly distributed lock.

๐พ S3 Billing in Cozystack โ Metering Object Storage
We've added S3 support to the our proprietary billing module (it could be installed over Cozystack). The billing API now recognizes S3 buckets as billable workloads and returns three consumption metrics per bucket:
โข S3StorageGiBHours โ logical volume ร time (how much the tenant actually stored)
โข S3PhysicalStorageGiBHours โ physical volume ร time (including replication factor)
โข LifetimeHours โ how long the bucket existed
โ๏ธ How It Works
The implementation reuses the same byte-seconds โ GiB-hours formula already used for PersistentVolumes. Tested end-to-end on a dev cluster with SeaweedFS CozyStack billing pipeline.
A UsageReport for a tenant with a bucket (10 MB, replication factor 2) looks like this:

โจ What This Gives ISPs
Cloud providers running on Cozystack or รnix Platform can now bill for object storage the same way as block storage and compute โ per-resource, per-minute, through a single UsageReport API.

Refactor complete. Swapped out MinIO for SeaweedFS. Added an encrypted blob export and local offline decrypt option too via the arkfile-client Go CLI util.
github.com/arkfile/Arkfile
Much of this would not be possible as a 1 man team w/o @PPQdotAI / @cline / @AnthropicAI Opus 4.6

Working on migrating fully to @SeaweedFS S3 API for local and self-hosted deployments of #Arkfile. Going to drop MinIO forever!

Nice! SeaweedFS already does this! Use FUSE mount to access the files in s3 buckets.

A really big S3 announcement - #S3 Files!!
If you've ever had to copy data out of S3 just so a file-based tool could use it, you know the frustration. S3 Files lets you mount S3 buckets as file systems directly, no data duplication, no sync pipelines, no workarounds. Your data stays in S3 while apps access it natively.
This looks really useful and a nice improvement over previous approaches like S3 Mount Point. AI agents, ML pipelines, and traditional file-based applications can all read and write to S3 as a file system without code changes. #aws #S3Files

That left Garage and SeaweedFS. After trying to set up both on my low-end Oracle VPS, SeaweedFS won me over!
Itโs incredibly lightweight, simple to get started with, and fits perfectly on my small AMD server.

How do you handle vibe-coded PRs? I am thinking to add these questions as the PR checklist:
1) Is this generated by AI?
2) If so, did you reviewed every line of code?
3) Is this PR as minimum as possible? If not, split into smaller PRs.

We all loved #MinIO for building neat demos locally that need S3โฆand then they went andย shuttered the project. I took a look at some of the alternatives, including @S3Proxy, @SeaweedFS, @RustFSofficial , #Garage, and @ApacheOzone.

Added SeaweedFS Mini for beginners! The easiest way to get an extensible object store up and running:

First came across Seaweed in 2018, working with the awesome @Jaumo team.
Had no idea it was a side project, itโs always been stellar.
Amazing work.
