8 self-hosted options in 2026

Best S3 Alternatives in 2026

AWS S3 charges $0.023/GB/month plus $0.09/GB egress. Self-hosting an S3-compatible storage on your own VM costs 5-10x less and egress is included. Here are the 8 best S3 alternatives in 2026, ranked by performance, ease of operation, and feature parity.

Context

Why teams are self-hosting S3 in 2026

Three trends are pushing teams away from AWS S3. The good news: in 2026, there are 8 mature open-source projects that implement the S3 API.

Egress costs

AWS charges $0.09 per GB for outbound bandwidth. A 1 TB monthly data transfer costs $90 in egress alone. On self-hosted S3, egress is included in your VM bandwidth.

Data sovereignty

European companies regulated by GDPR or working with public sector cannot host critical data on US cloud providers subject to the CLOUD Act. Self-hosting on EU infrastructure solves this.

Lock-in

AWS S3 features (lifecycle policies, replication, intelligent tiering) bind you to AWS. Open-source S3-compatible storage lets you move between providers and even on-premises.

The list

The 8 best S3 alternatives

Each implements the S3 API. Differences are in operational model, scale, and feature focus.

01

rustfs

Best performance per dollar in 2026

From $11/mo on Elestio.
Best for
Storing billions of small files (media, logs, document chunks).
Deploy SeaweedFS
05

Ceph

Best for enterprise distributed clusters

Ceph is a unified storage system supporting object (S3), block, and file storage. Strong enterprise adoption. Operational complexity is high.

Pricing
From $50/mo for production multi-node clusters on Elestio.
Best for
Enterprise teams with dedicated storage engineers, unified block+object+file needs.
06

OpenIO (MinIO fork)

Multi-tenant focused fork

OpenIO is a fork of MinIO now part of OVHcloud's storage stack. Multi-tenant features, strong fit for service providers offering S3 to their customers.

Pricing
From $11/mo on Elestio.
Best for
Multi-tenant S3-as-a-service offerings.
07

S3rver

Lightweight dev mock

S3rver is a Node.js-based S3 mock primarily used for local development and CI/CD testing. Not designed for production loads.

Pricing
Free, self-host on any Elestio VM ($11/mo).
Best for
Local development and CI/CD test environments.
08

Zenko (Scality)

Multi-cloud orchestration

Zenko provides an S3 API on top of multiple cloud backends. Useful for multi-cloud orchestration where you want a single API across AWS S3, Azure Blob, and Google Cloud Storage.

Pricing
From $25/mo on Elestio for production.
Best for
Multi-cloud storage orchestration with a single S3 API.

Pricing vs AWS S3

$473 vs $30 for 1 TB and 5 TB egress

Self-hosting wins by an order of magnitude when egress is in the mix.

SolutionStorageEgressTotal/month
AWS S3$23$450$473
Self-hosted on Hetzner (2 TB SSD + 20 TB BW)~$30$0 (included)$30
Self-hosted on AWS EC2 + EBS$50$450$500
Elestio rustfs / MinIO on HetznerIncludedIncluded$30-50

The savings come from two places: storage cost itself is comparable, but egress is included in your VM bandwidth on a self-hosted setup. For media serving, CDN origin, or backup distribution, the savings are dramatic.

Honest assessment

When NOT to self-host S3

Self-hosting is not always the right call. Skip it when:

  • You need 11 nines of durability guaranteed by AWS S3
  • You require deep integration with AWS services (Lambda, Athena, Glacier)
  • You have very low storage needs (less than 100 GB) where AWS S3 free tier suffices
  • You lack the ops capacity to monitor a storage cluster

For these cases, AWS S3 or Cloudflare R2 (zero egress fees) are better choices.

FAQ

Frequently Asked Questions

  • Is rustfs production-ready in 2026?

    Yes. rustfs reached v1.0 in early 2026 and has been adopted by several mid-market companies. It is younger than MinIO but the Rust implementation makes it remarkably stable and efficient.

  • Can I migrate my S3 buckets to a self-hosted setup?

    Yes. The tools listed all implement the S3 API. Use rclone or aws s3 sync to migrate buckets. Plan for the egress cost from AWS (one-time during migration) which can be significant for large datasets.

  • What about durability? AWS guarantees 11 nines.

    Self-hosted S3 with erasure coding (4+2 or 8+4) typically achieves 7-9 nines, which is enough for the vast majority of production workloads. For critical data, run multi-region replication (Garage is purpose-built for this).

  • What is the cheapest S3 alternative on Elestio?

    All of them deploy on the same $11/month starter VM. The cost is the VM, not the storage software (which is open source). For 1 TB+ storage, scale up to $30-80/month VMs.

  • Does Cloudflare R2 count as an S3 alternative?

    R2 is a cloud-hosted alternative (not self-hosted). It has zero egress fees, which is a major advantage if you serve a lot of bandwidth. But you do not own the infrastructure. For self-hosting with full control, the open-source options above are the way.

  • Can I use these with my existing AWS-SDK code?

    Yes. All listed tools implement the S3 API. Set your endpoint_url to your self-hosted instance instead of s3.amazonaws.com and the AWS SDK works without changes.
