5 Cheap Object Storage Providers in Europe in 2026

Object storage prices look simple until they do not.

One provider charges by GB-month. Another bundles bandwidth. Another adds request fees. Another has retrieval fees. Another has minimum retention. Another has cheap storage but expensive egress. This is how a bucket becomes a spreadsheet.

If you are in Europe and want cheap object storage for app uploads, backups, generated files, or static assets, these are five providers worth comparing.

What "cheap" means here

Cheap object storage is not just the lowest price per GB.

For a real app, cheap means:

• Low storage price
• Predictable egress cost
• No painful request fees
• S3 compatibility
• European or nearby region
• Good enough durability and reliability
• Low operational overhead

For a backup-only workload, low storage price may matter most. For an app serving files to users, egress and request fees can matter more than raw storage price.

Quick comparison

1. Sliplane Object Storage

Sliplane Object Storage is cheap in the way many apps actually need: the bill is predictable.

You get S3-compatible object storage for 5 EUR per 250 GB per month, excluding tax. The first GB is free. There are no egress fees, no ingress fees, and no request fees.

That means 250 GB of user uploads is 5 EUR/month. If users download files, still 5 EUR/month. If your app does lots of reads and writes, still no request fee line item.

Sliplane does not charge per bucket, so splitting uploads, backups, staging assets, and customer files into separate buckets does not change the bill.

Use Sliplane if:

• You want low and predictable pricing.
• You want German storage.
• You store app uploads, generated files, exports, or backups.
• You do not want to calculate egress.

Skip it if:

• You need less than a few GB and want a larger free tier.
• You need archive storage classes.
• You need many global regions.

2. Hetzner Object Storage

Hetzner Object Storage is very relevant for European developers because Hetzner is already known for strong price-performance.

It is S3-compatible, GDPR-compliant according to Hetzner's product page, and available in German and Finnish locations. Hetzner also supports features like versioning, object locking, and pre-signed URLs.

As of July 2026, Hetzner pricing starts at 6.49 EUR/month, excluding VAT, including 1 TB of storage and 1 TB of egress. Extra storage is listed at 8.70 EUR/TB-month, extra egress at 1 EUR/TB, and Hetzner lists ingress, internal eu-central traffic, and S3 API calls as free.

The caveat in 2026 is availability under load. On July 2, 2026, Hetzner's status page showed degraded Object Storage in multiple locations and an ongoing note that high Object Storage traffic may lead to timeouts. The durability and feature set can still make sense for backups or Hetzner-local workflows, but I would not make it the first choice for availability-sensitive app paths right now.

Use Hetzner if:

• You already run apps on Hetzner.
• You want German or Finnish infrastructure.
• You like building with infrastructure primitives.

Skip it if:

• You want object storage built into a PaaS.
• You want no egress or request fees in one simple sentence.
• You are not already in the Hetzner ecosystem.

3. Scaleway Object Storage

Scaleway Object Storage can be very cost-effective, especially if you pick the right storage class.

As of July 2026, Scaleway lists Standard One Zone and Standard Multi-AZ pricing separately, with Glacier for archive use cases. Requests and ingress are listed as included. Egress includes 75 GB free every month and then paid egress after that.

This makes Scaleway flexible, but also a little more complex than a flat storage product.

Use Scaleway if:

• You want storage classes.
• You need a European cloud provider.
• You can choose between availability/cost trade-offs.

Skip it if:

• You want no egress fees.
• You do not want to think about storage classes.
• You only need simple app upload storage.

4. Backblaze B2

Backblaze B2 is one of the most famous cheap object storage providers.

As of July 2026, B2 Cloud Storage starts at $6.95 per TB per month. Transactions are free, and egress is free up to 3x average monthly data stored. Additional egress is listed at $0.01 per GB.

For backup-heavy workloads, B2 is hard to ignore.

Use Backblaze B2 if:

• You store lots of backup or archive data.
• You want a low per-TB storage price.
• You are okay with the 3x egress allowance model.

Skip it if:

• You need German storage.
• Your app serves files all day.
• You want storage inside your app hosting platform.

5. IONOS Cloud Object Storage

IONOS Cloud Object Storage is a German option with per-GB storage pricing. As of July 2026, the IONOS pricing page lists object storage at $0.00487 per GB per 30 days, with free API operations.

The important detail is traffic. IONOS states that data transmission costs are not included and are added according to current pricing and traffic definitions.

Use IONOS if:

• You want a German provider.
• You already use IONOS.
• Your traffic model is easy to estimate.

Skip it if:

• You want no egress fees.
• You want pricing that is simple without reading traffic rules.
• You mainly want developer-friendly app storage.

Which cheap object storage provider should you choose?

Conclusion

For cheap European object storage, raw per-GB price is only half the story.

If your workload is mostly cold backups, Backblaze B2 and Scaleway can be very attractive. If you already live on IONOS, its storage product is worth evaluating. If you live on Hetzner, evaluate Object Storage too, but review current availability status before making it part of a critical serving path.

If you want cheap S3-compatible storage for an app and you hate surprise egress or request fees, Sliplane Object Storage is the straightforward choice.
