MinIO
S3-compatible object storage you can self-host anywhere — bare metal, VMs, or Kubernetes.
Self-hosted Open source AGPL-3.0 object-storages3self-hosting
Pricing
Free (open source). Enterprise support/features priced separately.
MinIO implements the S3 API closely enough that most tools built for S3 work against it unmodified, which makes it the default choice for self-hosted or air-gapped object storage.
Key features
- Drop-in S3 API compatibility
- Runs anywhere — bare metal, containers, Kubernetes
- No egress fees since it’s your own infrastructure
- Erasure coding for durability without full replication cost
Self-hosted vs. cloud
Self-hosted by design — you own the durability and backup story, in exchange for zero egress fees and no per-GB cloud pricing.
Quick start
docker run -d -p 9000:9000 -p 9001:9001 minio/minio server /data --console-address ':9001'
Alternatives
Amazon S3 is the managed alternative if you’d rather not run and back up storage infrastructure yourself.
