SeaweedFS scales to billions of files with O(1) disk seeks, S3 compatibility, and POSIX mounting - the distributed storage system that actually works at scale

Managing billions of files without your storage system collapsing is the kind of problem that keeps infrastructure engineers awake at night. SeaweedFS solves this with an elegant architecture that delivers O(1) disk seeks - meaning file access time stays constant whether you’re storing thousands or billions of files. While other distributed storage systems buckle under scale, SeaweedFS just keeps humming along.

What sets SeaweedFS apart is its incredible versatility without sacrificing performance. It speaks S3 API fluently, mounts as a POSIX filesystem via FUSE, integrates seamlessly with Kubernetes and Hadoop, and supports everything from cloud tiering to erasure coding. The dual-mode architecture separates metadata from data storage, giving you the speed of a blob store with the convenience of a traditional filesystem. Plus, with cross-datacenter replication and WebDAV support, it’s like having a Swiss Army knife for storage that actually excels at each function.

With 30K+ stars and active development, SeaweedFS has proven itself in production environments where downtime isn’t an option. The Go codebase is clean and the community is responsive - you can literally download binaries and have a distributed storage cluster running in minutes. Whether you’re building a data lake, need S3-compatible object storage, or want to replace expensive proprietary solutions, this is the storage system that scales with your ambitions.
