European Alternatives to Amazon S3
Looking for a European alternative to Amazon S3? Amazon's pricing page lists storage, request and retrieval, data transfer, management and replication charges as separate cost components, and bandwidth out of S3 is billed apart from the first 100 GB a month to the internet. Amazon Web Services, Inc. of Seattle contracts with customers outside EMEA (under the law of the State of Washington), while accounts in EMEA contract with Amazon Web Services EMEA SARL in Luxembourg.
The European providers below offer an S3-compatible API from a contracting entity in the EU, the UK or Switzerland, and several state flat per-terabyte prices with no egress or request fees.
How we rank these tools — 4-step process
-
1
European ownership, verified
The company is headquartered and incorporated in the EU, EEA, the UK, Switzerland or Israel, and processes customer data in Europe or Israel. A US parent company disqualifies a tool from this page regardless of where its servers are.
-
2
Category fit and hands-on review
What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.
-
3
Compliance and pricing check
GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.
-
4
Position on this page
Placement on this page can be paid, and that can affect which tools appear here and the order they appear in. It never buys a good review: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.
Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Vendors can pay for more visibility, higher up on the review pages; it never affects which tools are listed. Editorial policy

Key takeaways
- Amazon's pricing page lists storage, requests and retrievals, data transfer, management and replication as separate cost components, so the capacity price is only part of the bill.
- Bandwidth out of Amazon S3 is billed except for the first 100 GB a month to the internet, which sets the cost of leaving.
- Accounts in EMEA contract with Amazon Web Services EMEA SARL in Luxembourg, while accounts elsewhere contract with Amazon Web Services, Inc. under Washington law.
- Impossible Cloud lists EUR 7.99 per TB per month with egress and API calls free under a fair-use policy.
- Cloud Temple states 97 percent compatibility with the AWS S3 protocol, so lifecycle rules and bucket policies need testing before a production move.
Why people leave Amazon S3
Amazon S3 is the object store of Amazon Web Services, Inc., a company in Seattle, Washington. A bucket in it often becomes the longest-lived copy of a firm's data: database dumps, media libraries, log archives, backup repositories. Because so many backup and data tools write to the S3 API, the service is also the reference that the European providers on this page measure their compatibility against.
The reason people look elsewhere is rarely the storage itself. AWS's pricing page splits the bill into storage, requests and retrievals, data transfer, management features and replication, and bandwidth out to the internet is charged beyond the first 100 GB a month. A bucket that is mostly written and rarely read produces a small bill; a bucket that is read often produces a bill that is hard to forecast from the capacity alone.
The second reason is the contract. Accounts outside EMEA contract with Amazon Web Services, Inc. under the law of the State of Washington, while accounts in EMEA contract with Amazon Web Services EMEA SARL in Luxembourg. The Luxembourg entity gives European customers a local counterparty, but the group behind it is still American, which is the point where buyers with a sovereignty requirement start comparing.
- The invoice has five separate components Amazon lists storage, requests and retrievals, data transfer, management and replication as distinct charges. Each one is reasonable on its own, but a monthly estimate needs a read profile as well as a capacity figure. Six of the thirteen providers below state a flat or bundled price instead: Impossible Cloud, Safespring, OVHcloud, Cloud Temple, Cubbit and Contabo, with Hetzner folding 1 TB of egress into its base fee.
- Leaving costs money by design of the price list Only the first 100 GB a month of internet egress is exempt from Amazon's transfer charge. A company that wants to move 80 TB out has to pay for it on the way out, which is why several European providers advertise free egress as the opposite of lock-in. Safespring calls traffic charges a common lock-in mechanism on its own price page.
- The contracting party depends on where you sit Which Amazon entity signs your agreement depends on the country of the account, and the governing law follows it. A buyer who needs one clean answer to "which court, which law" gets a different answer from each European provider: German law at Impossible Cloud, Swiss law and courts at Exoscale, French law for the Cloud Temple website terms.
- Qualifications that Amazon does not hold for you Some buyers do not choose on price at all. Cloud Temple lists SecNumCloud, HDS and ISO 27001 on its object storage page, and Aruba Cloud says its service is qualified by the Italian ACN. If your procurement rules name a national qualification, a provider that holds it is a shorter path than an argument about how a hyperscaler region maps to it.
What you have to replace, not just match
Replacing Amazon S3 means replacing a set of behaviours, not just an endpoint. The basics (PUT, GET, multipart upload, pre-signed URLs, versioning, Object Lock) are listed by most providers here, and the tool you point at the bucket usually only needs a new endpoint URL and new keys. Anything you built around the bucket on the Amazon side, such as access policies, lifecycle rules between classes or replication, needs a separate decision and a test at the new provider.
Check the class structure next. Amazon prices storage, retrieval and management as separate lines, so a bucket may be using several classes without anyone remembering. European providers map unevenly onto that: OVHcloud sells four classes down to tape, Scaleway has a Glacier class, T Cloud Public has standard, warm and cold, and Impossible Cloud keeps everything in one hot tier. Move the data without mapping its classes and you either overpay for cold data or wait hours for a restore.
Finally, replace the paperwork. Your data processing agreement, your transfer impact assessment and your list of sub-processors all name Amazon today. A provider established in the EU, the UK or Switzerland changes those documents, and the exercise is a good moment to write down which buckets hold personal data at all.

How each alternative compares to Amazon S3
Best for: Backup repositories and AI training sets where read volume is hard to predict
Against Amazon S3, Impossible Cloud removes the arithmetic. The price page gives EUR 7.99 per TB per month and rules out fees on egress or API calls, while Amazon charges for storage, requests, transfer, management and replication one by one. A bucket with millions of small objects therefore does not add a request line next to the capacity line.
The price of that simplicity is one tier. Cold archives cost the same as active data, and free egress depends on a fair-use policy defined as traffic in line with normal workloads. The company is Impossible Cloud GmbH in Hamburg, German law governs the terms, and disputes go to arbitration, which is a different dispute route from a state court.
What Impossible Cloud does better than Amazon S3
- One listed price instead of five cost components
- No request or egress fees within the fair-use policy
- Contract with a German GmbH under German law
- 30-day trial without a credit card
Where Impossible Cloud is a step down from Amazon S3
- No colder class for rarely read data
- Founded in 2021, a shorter record than Amazon
- Arbitration with a class-action waiver
Standout against Amazon S3. It is the only provider here that sells a single price per TB for all use, with API calls free.
Best for: Swedish, Norwegian and public-sector buyers who prefer a Nordic operator and clear rates
Safespring AB, based in Solna, prices S3-storage at EUR 44.50 and S3-archive at EUR 31.15 per TB over 30 days, and states on its price page that no charge applies to traffic going in or out. Against Amazon, the two tiers give you the active-versus-archive split with two numbers instead of a matrix of classes and retrieval fees.
It is the more expensive route per terabyte, several times the flat rates of Impossible Cloud or Hetzner. What you pay for is the Nordic footprint, object locking for immutable backups and guides for s3fs, MinIO Client and the AWS CLI. The storage page gives no durability or availability figures, so ask for them in writing.
What Safespring does better than Amazon S3
- Two tier prices in euros per TB, no retrieval matrix
- Ingress and egress not charged
- Swedish company with a registered organisation number
- Object locking for immutable backups
Where Safespring is a step down from Amazon S3
- Several times the per-TB rate of the cheapest providers
- Nordic footprint only
- No durability or availability figures on the storage page
Standout against Amazon S3. It states in writing that traffic charges are a lock-in mechanism it does not use.
Best for: Service providers and organisations that want S3 on their own hardware or across sites
Cubbit, a Bologna company, offers its storage technology in two forms. DS3 Cloud is hosted by partners in EU or UK facilities, and DS3 Composer is software that runs on your own servers, on bare metal or in a public cloud. Against Amazon S3, that is the one option here where the endpoint can sit inside your own building.
Pricing is the soft spot. No public rate exists for DS3 Cloud, which is sold through partner quotes, and the numbers shown belong to Composer alone: nothing up to 3 TB, then EUR 4.99 per TB a month for volumes of 3 to 10 TB. Cubbit claims savings of up to 80 percent against hyperscalers but publishes no calculation, so treat the figure as a vendor claim until you have a quote.
What Cubbit does better than Amazon S3
- Can run on your own infrastructure
- Geo-distribution is part of the base service
- No egress, deletion or API fees stated
- White-label option for resellers
Where Cubbit is a step down from Amazon S3
- No public price for DS3 Cloud
- Hosted data sits in partner data centers
- Composer rate listed only up to 10 TB
Standout against Amazon S3. It is the one provider where the same S3 technology runs hosted or on your own servers.
Best for: Small teams that value one easily forecast monthly floor for a single bucket
Where Amazon splits the invoice into components, Hetzner charges a EUR 6.49 monthly base in which 1 TB of storage and 1 TB of egress are already covered, with usage above that billed on top. The locations are Falkenstein, Nuremberg and Helsinki, and the service lists object locking, so it covers the common backup case with a German contract.
There are details to read. Objects below 64 KB are billed as 64 KB, which matters for buckets holding millions of tiny files, and the catalogue around the bucket is narrower than Amazon's. You get storage, not an event system or a family of data services, so anything that reacts to an upload needs to be rebuilt in your own code.
What Hetzner does better than Amazon S3
- Storage and egress included in a small base fee
- Object locking for immutable backups
- German contracting entity
- Simple to estimate for a single bucket
Where Hetzner is a step down from Amazon S3
- Minimum billing size of 64 KB per object
- Three locations in two countries
- Far fewer services around the bucket
Standout against Amazon S3. The starting fee already covers a terabyte each of storage and egress, so a trial bucket costs little to try.
Best for: Teams that already use storage classes and want the same layering in France
Scaleway is the provider here whose structure resembles Amazon's most. It sells Multi-AZ and One Zone storage and a Glacier cold class, priced per GB and per hour, and states that it does not charge request fees. A move from Amazon therefore keeps the mental model of hot, one-zone and archive data.
Egress is not free: the page lists 75 GB a month included, then EUR 0.01 per GB. Scaleway is a subsidiary of the Iliad Group in Paris, with the Paris price table the one checked here. We could not read the governing law of the contract, because the terms are in a PDF, so confirm it with sales.
What Scaleway does better than Amazon S3
- Multi-AZ, One Zone and a Glacier class like Amazon
- No request fees
- Hourly pricing for short-lived data
- French company inside a European group
Where Scaleway is a step down from Amazon S3
- Egress charged beyond 75 GB a month
- Governing law not confirmed from the PDF terms
Standout against Amazon S3. It combines a Glacier cold class and Multi-AZ replication with a European contracting party.
Best for: Buyers who want Swiss jurisdiction and the choice of several European zones
Exoscale sells S3-compatible storage under Swiss law and courts, with data centers in several European countries. Versioning, object lock and bucket replication are named, which covers the usual protection and disaster-recovery requirements that Amazon buyers raise.
Two cautions. Switzerland is outside the EEA, covered by an adequacy decision rather than by EU membership, which some legal teams treat differently. And the object storage prices on its pages are rendered in the browser, so no figure was read for this page; ask for a quote before you compare it with the flat rates.
What Exoscale does better than Amazon S3
- Swiss law and courts in the contract
- Bucket replication and Object Lock listed
- Wide choice of European zones
- Belongs to the A1 Digital group
Where Exoscale is a step down from Amazon S3
- Outside the EEA, relying on the Swiss adequacy decision
- Object storage prices not visible on the pages read
Standout against Amazon S3. It is the only Swiss-law contract among the thirteen.
Best for: Backup-heavy buyers who want a cold tape class and Veeam support
OVHcloud offers four classes, from hot HDD storage to a Cold Archive on tape, and states that egress and API calls are not charged. Against Amazon, where each class brings retrieval and transfer lines, that is an easier bill to predict, and the page names Veeam and HYCU as supported backup software.
Minimum storage periods of 30, 90 and 180 days apply to the colder classes, which means early deletions are still billed. No euro price appeared on the server-rendered page and the governing law was not checked, so request the price list and the contract before you plan a migration.
What OVHcloud does better than Amazon S3
- Cold storage on tape, a class few providers here sell
- No egress or API fees stated
- Named Veeam and HYCU support
- French company with its own data centers
Where OVHcloud is a step down from Amazon S3
- Minimum periods of 30, 90 and 180 days on colder classes
- No euro price on the page read
- Class choice adds a planning step
Standout against Amazon S3. It is the only provider on the page with an archive class stored on tape.
Best for: German-speaking buyers wanting hourly billing and an archiving class
STACKIT is the cloud of Schwarz Digits, and its object storage is billed hourly, with locations in Germany and Austria and an archiving class. For a team that provisions buckets for projects that last weeks, hourly billing is a closer match than a monthly minimum.
The product page does not state egress or request fees, so total cost cannot be modelled from it. The terms URL returned a 404 when read, which means the governing law was not confirmed. Treat it as a candidate to ask about, and get both answers in writing.
What STACKIT does better than Amazon S3
- Hourly billing for temporary buckets
- German and Austrian locations
- Archiving class listed
- German group as the contracting party
Where STACKIT is a step down from Amazon S3
- Egress and request fees not stated
- Governing law not confirmed
- Only two countries
Standout against Amazon S3. It bills storage per hour, which suits project buckets that exist only for a few weeks.
Best for: French public bodies, hospitals and regulated firms that need a qualified endpoint
Cloud Temple runs its object storage on Dell ECS in region FR1 with three availability zones, and lists EUR 0.018 per GiB per month excluding VAT, with public and internal traffic included. The product page names SecNumCloud, HDS, ISO 27001 and C5, which is the reason to choose it over Amazon when procurement rules ask for French qualification.
Compatibility is stated at 97 percent, so test lifecycle rules and bucket policies. Object Lock is listed for the second half of 2026 and on request through support, so immutable backups are not available by default today. Only one priced region exists, and the terms read cover the website, not the service contract.
What Cloud Temple does better than Amazon S3
- SecNumCloud, HDS and ISO 27001 on the product page
- Traffic included in the price
- Three-zone replication with 12+4 erasure coding
- Price per GiB in euros
Where Cloud Temple is a step down from Amazon S3
- 97 percent S3 compatibility
- Object Lock not yet generally available
- One priced region
Standout against Amazon S3. It combines a French qualification with a listed euro price per GiB.
Best for: Italian companies and public bodies wanting a domestic provider and a fixed package
Aruba Cloud has two commercial routes for object storage. One is metered use starting at EUR 0.00028 an hour per 10 GB, the other a monthly package from EUR 60 plus VAT that bundles 4 TB of storage with 40 TB of outbound traffic. The service is described as ACN-qualified and runs on Ceph over NVMe disks in seven data centers.
Unlike most providers here, it charges for traffic out: EUR 0.50 plus VAT per 10 GB on pay-per-use. The headline "from EUR 0.011 per GB" does not match the pay-per-use arithmetic, so the lowest figure seems to belong to the package route. The page gives no durability figures or data center cities.
What Aruba Cloud does better than Amazon S3
- ACN qualification for Italian public administration
- Package price with a traffic allowance
- Choice among seven data centers
- 24/7 technical support
Where Aruba Cloud is a step down from Amazon S3
- Outgoing traffic is charged
- No durability or availability figures
- Two price routes that do not reconcile
Standout against Amazon S3. It is the only provider here that sells a fixed monthly package with an outgoing traffic allowance.
Best for: Buyers already on IONOS hosting who want Object Lock and no request charges
IONOS Cloud bills storage by usage, states that API calls are free and lists Object Lock. The data centers named are in Germany and Spain. A German page shows EUR 0.007 per GB per 30 days, which we read only there. The contracting entity is IONOS Cloud GmbH of Montabaur, registered as HRB 31110.
Who sells to you depends on the site, since pages aimed at the US name IONOS Cloud USA Inc. Open the account through the German or UK site and choose a European region at bucket creation. The governing law was not checked, so ask for the terms.
What IONOS Cloud does better than Amazon S3
- API calls not charged
- Object Lock available
- German and Spanish data centers
- Fits alongside IONOS hosting and domains
Where IONOS Cloud is a step down from Amazon S3
- Different legal entity on US-facing pages
- Price read on one site only
Standout against Amazon S3. It states free API calls together with Object Lock, from a company with a German registered number.
Best for: Enterprises that already contract with Deutsche Telekom or T-Systems
T Cloud Public, called Open Telekom Cloud until January 2026, offers its Object Storage Service through REST and the S3 protocol. T-Systems International GmbH in Frankfurt runs it, and it lists standard, warm and cold classes, each spread over three availability zones, plus lifecycle rules, versioning, bucket policies and IAM.
No storage price appears on the product page, so comparison needs the price calculator or the service description PDF; an EUR 250 starting credit runs to 31 December 2026. Cold retrieval takes hours in the standard mode, and the S3 compatibility level is not stated, so test your tools first.
What T Cloud Public does better than Amazon S3
- Three availability zones for every class
- Lifecycle rules, versioning and IAM listed
- Cross-region replication added in 2026
- Contract with a registered German entity
Where T Cloud Public is a step down from Amazon S3
- No price on the product page
- Cold retrieval takes hours
- Rename means older documentation uses another name
Standout against Amazon S3. Every class sits in three availability zones, including the cold one.
Best for: Existing Contabo customers who want cheap bucket space next to their servers
Contabo sells object storage as a flat rate per tier with unlimited transfer, so a bucket has no egress line at all, unlike Amazon's transfer charge beyond 100 GB. The seller is Contabo GmbH in Munich, and the terms are under German law.
There is a restriction: the product is described as available only to existing Contabo customers, so it is not a starting point if you have no account there. The registration number was not read for this page, and the offer should be read as an add-on to a server relationship, not as a standalone Amazon replacement.
What Contabo does better than Amazon S3
- Flat rate per tier
- Unlimited transfer
- German contract and law
Where Contabo is a step down from Amazon S3
- Only for existing Contabo customers
- Few storage features documented
Standout against Amazon S3. Transfer is unlimited on a flat tier price, with no egress line to model.
What actually breaks when you switch
The first thing that breaks is the data move itself. Amazon bills transfer out beyond the first 100 GB a month, so copying a large bucket to a European provider is itself a charge on the Amazon side. Plan the copy in slices, use a tool such as rclone from a machine close to the source, and compare the one-off egress figure with the yearly saving before you start.
The second break is everything that referred to the bucket by name or policy. Application config, pre-signed URLs already handed to customers, bucket policies, event triggers and lifecycle rules do not move with the objects.
Providers differ here: T Cloud Public has IAM and bucket policies, Cloud Temple states 97 percent compatibility, and Cubbit and Impossible Cloud list versioning and immutability. Run a staging copy, then switch DNS and endpoints during a quiet window, and keep the old bucket read-only until a full restore test has passed.
Will my backup software still write to the bucket after I leave Amazon S3?
In most cases yes, because the tools address the bucket through the S3 API and only need a different endpoint and keys. Impossible Cloud names Veeam as a native target and lists Acronis, NAKIVO, MSP360 and Hornetsecurity, OVHcloud lists Veeam and HYCU, and Safespring names Veeam Backup, Nextcloud and Cyberduck on its storage page.
Immutability is the part to verify. Hetzner, OVHcloud, IONOS Cloud, Exoscale, Safespring and Impossible Cloud mention Object Lock or object locking, whereas Cloud Temple states that its Object Lock arrives in the second half of 2026 and is activated through a support request. Write one backup, set the retention, and try to delete it before you trust the target.
Does moving the bucket to Europe remove the US jurisdiction question?
It removes the American contracting entity if you choose a provider headquartered in Europe. Amazon's European accounts already contract with a Luxembourg company, so the data sits in an EU region and the signatory is European, but the parent is Amazon Web Services, Inc. A provider such as Safespring AB in Sweden or Aruba S.p.A. in Italy has no American parent.
Look at who owns the provider as well. Exoscale sits inside A1 Digital and Scaleway inside the Iliad Group, and both groups are European. IONOS shows a US legal entity on its US-facing pages, so create the account on the German or UK site and pick a European region when you create the bucket.
Which one to pick
For backups and archives with an unpredictable restore pattern, the flat-price providers are the natural start. Impossible Cloud lists EUR 7.99 per TB with egress and API calls free under fair use, Safespring offers archive and active tiers from Sweden, and OVHcloud adds tape. Hetzner suits a small first bucket because storage and egress are bundled in the EUR 6.49 base fee.
Choose by constraint when price is not the lead. Cloud Temple fits French regulated buyers, Aruba Cloud fits Italian public bodies, Exoscale gives Swiss law, Cubbit lets you run the system on your own hardware, and Scaleway keeps the class structure closest to Amazon. Stay on Amazon for buckets tightly wired to other Amazon services; the sensible path is to move the easy buckets first.
Frequently Asked Questions
That turns on how often the data is read. Impossible Cloud quotes a single EUR 7.99 per TB per month covering egress and API calls, Hetzner asks a EUR 6.49 base fee in which 1 TB of storage and 1 TB of egress are already included, and Safespring splits archive from active data in Sweden. Cloud Temple fits French regulated buyers who need SecNumCloud.
Not entirely. Providers describe their services as S3-compatible and name tools such as rclone, Veeam and the AWS CLI, but compatibility is a degree. Cloud Temple states 97 percent. Test multipart uploads, lifecycle rules, bucket policies and pre-signed URLs against a copy of your data before you switch a production workload.
Amazon bills bandwidth out of S3 except for the first 100 GB a month to the internet. A bucket that serves downloads or feeds a data pipeline therefore carries a transfer line that grows with use. OVHcloud, Safespring, Impossible Cloud and Cloud Temple state that outgoing traffic is not billed, whereas Aruba Cloud charges EUR 0.50 per 10 GB on its pay-per-use plan.
According to the AWS customer agreement as read for this page, accounts in EMEA contract with Amazon Web Services EMEA SARL in Luxembourg, and other accounts with Amazon Web Services, Inc., governed by the law of the State of Washington. The Luxembourg entity is European, but the group above it is American.
Yes, because the API is shared. Many teams move backup and archive buckets first, since those have the simplest access pattern and the clearest price gap, and leave buckets that depend on other Amazon services where they are. Mark each bucket with the services that read it before you decide.
