1.8
GPA, above 1 of the 45 other file storage and sync services we grade

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | €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. |
| Free plan and trial | C | Composer 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. |
| Features | C | S3 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. |
| Ease of use | D | Composer nodes need a Linux machine with at least 1 vCore and 2 GB of RAM per drive. No rating on record. |
| Platforms and integrations | C | Web console and an S3 API only. The listing names no integrations and no apps. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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
Good to know
Good for
- Organizations that need data kept in the EU
- Teams wanting S3 storage on hardware they choose
- Backup and archive workloads sized in terabytes
Worth knowing
- Prices are in euros and are read from the pricing page's FAQ; no price is published for DS3 Cloud.
- Above 10 TB, pricing is a custom quote.
- Composer nodes need a Linux machine with at least 1 vCore and 2 GB of RAM per drive.
- It targets IT teams and developers rather than everyday file sharing.

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.
