SeaweedFS

API

Distributed S3-compatible object store and file system for billions of files

Price: Free, open source; paid Enterprise
Access: S3 access keys, optional in development

About

SeaweedFS is an open-source distributed storage system. One weed binary serves an S3-compatible object store, a file system over HTTP, WebDAV and FUSE, and Iceberg tables. A small file takes one disk read, and capacity grows by adding volume servers. A paid Enterprise edition adds recovery features.

What you can do with it

Store and serve billions of small files such as user uploads and images
Run an S3-compatible endpoint with presigned URLs on your own servers
Mount the same files over FUSE or WebDAV and replicate them across data centers

Get started

Install the weed binary or run the chrislusf/seaweedfs Docker image
Start a single-node S3 store and a bucket with weed mini
Point an S3 SDK or the AWS CLI at port 8333
