S3 Exit • MinIO Successor

Managed RustFS

Production-grade RustFS hosting in Frankfurt, Germany.

We run RustFS 1.0 for you: S3-compatible, usage-based pricing, 24/7 operations. You get the MinIO successor in production without building your own storage ops team.

Initial situation

MinIO is in maintenance mode. S3 keeps getting more expensive

In December 2025, MinIO Inc. stopped active development of the open-source version. Running MinIO today means running legacy software. Staying on S3 means unpredictable egress bills and US jurisdiction over your data. RustFS, the open-source MinIO successor, fixes both. Since version 1.0 (16 September 2026), its core S3 engine is GA and production-ready.

  • Same S3 API as MinIO: your applications keep working without code changes
  • 2.3x faster than MinIO on small objects
  • Apache 2.0 licensed — no AGPL surprises
  • GA since September 2026, still a young project: which is exactly why managed operations matter

Why RustFS Is the Future of S3-Compatible Storage

Same S3 API, no code changes

Your applications talk to RustFS the way they talked to MinIO: same API, same SDKs. We copy your buckets with checksum verification, run old and new storage in parallel and switch over without downtime. MinIO's on-disk format is still in preview in RustFS, so we migrate by copy, not by swapping the binary.

Predictable Costs

Usage-based pricing at 0.03 €/GB/month. No egress billing, no API-call surprises. A 15 TB workload costs about 5,530 €/year — the same workload on AWS S3 runs 268,000 €/year.

EU Data Sovereignty

Your data lives in our Frankfurt data center, under German law, powered by renewable energy. GDPR compliance you own — not compliance you rent from a hyperscaler.

Transparent pricing

Packages & Prices

All prices are net. One pricing model — no tiers, no egress fees, no surprises.

Audit

From S3 to RustFS in six weeks — zero downtime

01

Audit

Bucket inventory, access patterns, data classification

02

Parallel deploy

RustFS runs next to S3, dual-write enabled, production untouched

03

Cutover

Reads switch to RustFS; S3 stays as read-only fallback for 30 days

04

Operation

We run it 24/7; you decommission S3 and stop paying egress

RustFS or Ceph? Two ways to exit S3.

Both run in our Frankfurt data center, both speak S3, both end your hyperscaler dependency. RustFS is the lightweight choice for backups, logs and S3 workloads — and the natural path off MinIO. Ceph is the enterprise platform for block, file and object storage at petabyte scale, production-proven for over a decade. Not sure which fits? That’s what the 30-minute call is for.

RustFS is young. Here’s how we make it safe.

RustFS 1.0 is GA, and the project marks its core S3 engine as production-ready. What it does not have yet is a long production history like Ceph’s. That is the gap a managed service closes.

We carry the operations

We patch security issues immediately, test every new release in staging before it touches your data, and keep preview features off in production until the project marks them stable.

You get a real SLA

99.9% availability, in the contract. Self-hosted, your availability is whatever your ops team can do at 2 a.m.

You’re never locked in

RustFS is Apache 2.0 open source. Take your data and run it yourself anytime — we’ll even help you leave. That’s the point of an exit.

FAQ

Frequently Asked Questions

Is RustFS production-ready?

Yes, for core S3 object storage, since version 1.0.0 (16 September 2026). Two features are still in preview: S3 Tables and MinIO on-disk compatibility. We keep them off in production until the project marks them stable.

Can RustFS replace MinIO?

Yes, at the API level: applications keep working without code changes. Existing data moves by copy, with checksum verification, because reading MinIO data in place is still a preview feature in RustFS.

Is RustFS fully S3-compatible?

It covers the S3 API including versioning, WORM/object locking, encryption and replication. We verify your specific API calls during the proof of concept.

What happens if the RustFS project dies?

Your data is stored behind a standard S3 API and is migratable at any time — to Ceph in the same data center, to any S3-compatible store, or to hardware you own. No proprietary formats, no exit fees.

Where is my data stored?

In our Frankfurt data center, operated under German law and powered by renewable energy. Data never leaves Germany.

How long does migration from S3 take?

Around six weeks for a typical 15 TB setup, with zero downtime: parallel deployment, dual-write, checksum verification, then cutover with a 30-day S3 fallback.
