S3 Exit • MinIO Successor
Managed RustFS
Production-grade RustFS hosting in Frankfurt, Germany.
We run the MinIO successor for you — S3-compatible, usage-based pricing, 24/7 operations. You get the future of object storage without betting your data on alpha software.
MinIO timeline
Initial situation
MinIO is in maintenance mode. S3 keeps getting more expensive maintenance mode
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, but its documentation is explicit: not production-ready yet.
- Drop-in MinIO replacement — same S3 API, same buckets, no code changes
- 2.3x faster than MinIO on small objects
- Apache 2.0 licensed — no AGPL surprises
- Alpha software — which is exactly why managed operations matter

Why RustFS Is the Future of S3-Compatible Storage
Drop-in MinIO Replacement
Stop your MinIO server, swap the binary, start RustFS. Data, buckets and configuration are preserved. No migration scripts, no downtime, not a single line of application code changed.
Predictable Costs
Usage-based pricing at 0.03 €/GB/month. No egress billing, no API-call surprises. A 15 TB workload costs about 5,500 €/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.

MinIO Exit Assessment
Running MinIO in production? We audit your cluster, map the migration path and give you a fixed quote. Free with any 30-minute consultation.
Migration
From S3 to RustFS in six weeks — zero downtime six weeks
Audit / Bucket inventory, access patterns, data classification
Clarify inventory and requirements
Parallel deploy / RustFS runs next to S3, dual-write enabled, production untouched
Define connectivity, access, and SLA
Cutover / Reads switch to RustFS; S3 stays as read-only fallback for 30 days
Planned migration with fallback
Operation / We run it 24/7; you decommission S3 and stop paying egress
Continuous optimization
RustFS or Ceph? Two ways to exit S3.
Substantial Cost Savings
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.
| Criterion | Managed RustFS | Managed Ceph |
|---|---|---|
Best for | S3 / MinIO replacement, backups, logs | Enterprise storage platform |
Maturity | Alpha (we absorb the risk) | Production-proven since 2012 |
Block & file storage | No — object storage only | Yes (RBD, CephFS) |
MinIO drop-in | Yes | No |
Pricing | 0.03 €/GB/month | Custom quote |
RustFS is alpha software. Here’s how we make it safe.
We won’t hide it: the RustFS docs say “do not use in production.” That is exactly the gap a managed service closes.
We absorb the risk
Security issue in RustFS? We patch it immediately — that’s our job, not yours. Our engineers run the cluster, watch upstream development and test every release before it touches your data.
You get a real SLA
99.9% availability, contractually. With DIY alpha software you get whatever your ops capacity allows 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.
