Developer Compares MinIO and SeaweedFS for Self-Hosted Object Storage

A developer building a media-heavy FastAPI application evaluated two self-hosted object storage solutions after finding MinIO's enterprise features increasingly tied to paid subscriptions. MinIO, known for its S3 compatibility and simple single-binary setup, was the initial choice due to its ease of use and seamless boto3 integration. SeaweedFS emerged as an alternative, offering a distributed architecture with its own filer and volume server system that also exposes an S3-compatible API. The key distinction noted was that MinIO behaves like S3 running on a private server, while SeaweedFS is a purpose-built distributed storage system that speaks the S3 protocol as one of its interfaces. For deployments requiring predictable costs and full client control, the developer concluded both tools are viable but serve subtly different infrastructure needs.
