Best for S3-compatible storage for IT teams in Europe
Cubbit sells S3-compatible object storage from a flat €4.99 a terabyte a month, with no charges for egress or API calls. The free 3 TB tier means running nodes yourself on Linux machines, and the hosted version is a quote.
Who Cubbit is for
- Fits if you run IT and want S3 storage that stays in Europe
- Works for developers who'll run storage nodes on their own hardware
Who Cubbit is not for
- Not for you if you want an app to sync and share files, as it targets IT teams and developers
- Skip it if you don't have a Linux machine to spare, since the free Composer tier runs on your own hardware
- Watch out: DS3 Cloud has no published price, and above 10 TB it's a custom quote
- Watch out: prices are in euros and come from the pricing page's FAQ
- Too light for anyone who wants listed integrations, as none are named
Why Cubbit gets a 1.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for money€4.99 a TB a month for 3 to 10 TB, which is cheap per terabyte, but the free and low rates are for Composer, where you run the nodes yourself. Hosted DS3 Cloud has no published price.
- CFree plan and trialComposer is free up to 3 TB, but you need your own Linux machine for it. The hosted cloud gets a 30-day, 1 TB demo and no credit card is needed.
- CFeaturesS3 compatibility, geo-redundancy and a flat rate with no egress or API fees. It's an object store for IT teams, not a file sharing or sync tool.
- DEase of useComposer nodes need a Linux machine with at least 1 vCore and 2 GB of RAM per drive. No rating on record.
- CPlatforms and integrationsWeb console and an S3 API only. The listing names no integrations and no apps.

Keep Cubbit, or make your own?
Keep it
Nothing Cubbit does is plain enough to make in a weekend. The 2 things listed below take a company.
That makes this kind of software worth paying for, not this one in particular: 42 of the 45 other file storage and sync services grade higher. It costs $66.90 a year.
What you could not
- A file manager working directly on your disk.
- An API that other software can build on.
What this rests on. Cubbit’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.
