Best for S3-compatible object storage for engineers

MinIO sells AIStor, S3-compatible object storage for engineering and data teams. The free version is a single node with no resilience, clusters need quoted Enterprise subscriptions, and the pricing page calls the old open source edition end of life.

Who MinIO is for

Fits if you run your own infrastructure and need S3-style storage
Works for data teams that want a single test node for free

Who MinIO is not for

Not for you if you want a file-sync or sharing app
Not for you if you want a managed service, as it runs on your own servers
Watch out: the pricing page says the original AGPLv3 edition is end of life with no fixes or security patches
Watch out: clusters need a paid subscription whose price is not published

Why MinIO gets a 2.2

Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.

CValue for moneyThe free tier is single-node and Enterprise Lite and Enterprise are quoted on request, so there is no price to compare.
BFree plan and trialFree single-node deployment with the full feature set and community support. Redistribution is prohibited, and there is a 60-day trial of the paid tiers.
CFeaturesS3 API, replication, security and management for object storage. It is not a file-sync app, and clustering is paid.
DEase of useDeployed on your own servers or cloud and run by operators. No store rating on record.
BPlatforms and integrationsWeb console, S3 API and Kubernetes, Prometheus, NVIDIA and Databricks listed.

Keep MinIO, or make your own?

Keep it

Nothing MinIO does is plain enough to make in a weekend. The 3 things listed below take a company.

What you could not

A file manager working directly on your disk.
It plugs into other products, NVIDIA, Databricks and Kubernetes among them, and has an API.
What a company asks for before it lets staff use something: SOC 2 and roles and permissions.

What this rests on. MinIO’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.

What is MinIO?

MinIO makes AIStor, object storage software that speaks the S3 API and also covers Iceberg tables and SFTP, deployed on your own servers or cloud. It is aimed at engineering and data teams rather than people who want a file-sync app. The original open-source edition is described on the pricing page as end of life.

Worth knowing

Clustered, highly available deployments need a paid Enterprise Lite or Enterprise subscription; the free tier is single-node only.
No Enterprise Lite or Enterprise prices are published; both are quoted on request.
The pricing page says the original open-source MinIO edition (AGPLv3) is end of life with no fixes or security patches.
This is infrastructure software for operators, not a consumer file-sync or sharing app.

Key features

S3-compatible object storage: AIStor is described as fully S3-compatible, with S3 Express, an Iceberg catalog and SFTP also listed among its protocols.
Replication: The feature list names active-active, synchronous and asynchronous, multi-site, bucket and batch replication.
Security: Encryption, a key management server, a data firewall and immutability are listed, and the page shows FIPS 140-3, SOC 2 and ISO 27001 badges.
Management: An admin console, quality-of-service controls, lifecycle management, audit trail and Prometheus metrics are listed.
Sized by usable capacity: Subscription pricing follows usable storage capacity after erasure-code overhead, not raw disk.
