The short version

  • Each has a real cost: MinIO the AGPL v3 licence applies copyleft over network use, so embedding MinIO in a product or hosted service obliges you to release your own source or buy a commercial licence, and legal review has removed it from several vendor stacks for this reason alone.; Storj billing includes a per segment charge and every object consumes at least one segment, so a bucket holding millions of small files can cost several times what the four dollar per terabyte headline implies.
  • They diverge on capability: MinIO covers S3 API implementation, Storj covers Erasure coded distribution.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

MinIO

  • Providing an S3 endpoint inside an air gapped or regulated network where a cloud bucket is not permittednot Storj
  • Backing a Kubernetes platform with object storage that lives on the same hardware as the clusternot Storj
  • Standing up S3 semantics in CI so tests exercise the same API path as productionnot Storj
  • Fronting local disk shelves with an S3 interface so applications only ever learn one storage APInot Storj

Storj

  • An offsite backup or archive target where the data is large, written once and occasionally restorednot MinIO
  • Serving large media files internationally without paying hyperscaler egress ratesnot MinIO
  • Storing data where the objection to AWS, Azure or Google is jurisdiction and concentration rather than costnot MinIO
  • A second, independent copy of a dataset that already lives in a hyperscaler bucketnot MinIO

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

MinIO

  • The AGPL v3 licence applies copyleft over network use, so embedding MinIO in a product or hosted service obliges you to release your own source or buy a commercial licence, and legal review has removed it from several vendor stacks for this reason alone.
  • The community edition console was reduced in 2025 to an object browser, so user, policy, bucket and configuration management now happen through the mc command line client or through the paid product, which is a real operational regression for teams that trained staff on the UI.
  • The vendor has changed the terms of the free edition twice, so planning long lived infrastructure around the community build carries the risk that the next change removes something you depend on.
  • Erasure coded deployments cannot be grown by adding single drives; capacity is added in server pools, so expansion is a hardware purchase in units rather than an incremental one.
  • Commercial pricing is capacity based and aimed at large deployments, so a team that outgrows the community edition faces an enterprise sized quote rather than a graduated upgrade path.

Storj

  • Billing includes a per segment charge and every object consumes at least one segment, so a bucket holding millions of small files can cost several times what the four dollar per terabyte headline implies.
  • Reconstructing an object requires responses from dozens of independent nodes, so time to first byte is noticeably higher than a centralised bucket and it is a poor fit behind a latency sensitive read path.
  • Performance depends on the mix of node operators serving you at that moment rather than on a datacentre you can raise a ticket against, so slow reads are diagnosed statistically rather than fixed.
  • The hosted S3 gateway terminates encryption on Storj infrastructure, so using the convenient access path gives up the end to end encryption that is the main architectural argument for the service.
  • The S3 gateway is compatible rather than identical, so tools that lean on less common API calls, multipart edge cases or unusual header behaviour need testing before you commit a workload to it.

Questions people ask

Is MinIO or Storj better?
Neither clearly leads. MinIO starts at Free and Storj at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, MinIO or Storj?
MinIO starts at Free and Storj at Free.
Does MinIO or Storj run on more platforms?
MinIO runs on Linux, macOS, Windows, Kubernetes, Docker. Storj runs on Web, API, Linux, macOS, Windows.
Can I use MinIO for free?
Both have a free tier, so you can try either at no cost before committing.
What is MinIO best used for?
MinIO is most often used for providing an s3 endpoint inside an air gapped or regulated network where a cloud bucket is not permitted, backing a kubernetes platform with object storage that lives on the same hardware as the cluster, standing up s3 semantics in ci so tests exercise the same api path as production, fronting local disk shelves with an s3 interface so applications only ever learn one storage api. Of those, providing an s3 endpoint inside an air gapped or regulated network where a cloud bucket is not permitted and backing a kubernetes platform with object storage that lives on the same hardware as the cluster are not what Storj is typically brought in for.
What can MinIO do that Storj cannot?
MinIO covers S3 API implementation, Erasure coding, Single binary deployment, Bucket replication. Storj covers Erasure coded distribution, Client side encryption, S3-compatible gateway, Native uplink access.

Answered from the vendors’ own pages

MinIO: Can I still use MinIO for free?

Yes, the AGPL v3 server remains available and functional. What changed is the console, which no longer manages users, policies or configuration in the community build.

Storj: Why is my bill higher than four dollars per terabyte?

Almost always the per segment fee. Objects are split into segments and small files each consume one, so a few million tiny objects generate a segment charge that dwarfs the storage line.

MinIO: Does AGPL affect me if I only use it internally?

Internal use without offering the software over a network to third parties generally does not trigger the source obligation, but if MinIO forms part of a service you offer to others, it does. Take advice rather than a forum answer.

Storj: Can node operators read my data?

No. Files are encrypted client side and each operator holds only an erasure coded fragment, which is not a readable portion of the file.

MinIO: What replaced the community console features?

The mc client and the server admin API. Third party UIs exist but they are not maintained by MinIO.

Storj: Is there a minimum retention period?

No. You are billed for what you store while you store it, unlike several competitors that bill a ninety day minimum whatever you delete.

MinIO: Is it suitable as a Veeam or restic backup target?

Yes, object locking and versioning work and both tools treat it as standard S3. Immutability depends on configuring the lock policy at bucket creation.

Storj: Is it fast enough to serve a website from?

For large files with parallel reads, yes. For many small objects where time to first byte matters, put a CDN in front of it or use something centralised.
