Where to host a web app in Spain in 2026

If your servers must physically sit in Spain, pick a local provider or a big cloud's Spanish region. Clouding.io in Barcelona and Arsys in Logroño are Spanish companies selling servers from data centres in Spain, Stackscale rents dedicated hardware in Madrid, while AWS, Google Cloud and Microsoft Azure each run a cloud region in Spain under a US parent. If you only need your app hosted inside the EU, a managed platform such as Eurobase deploys from Git without a server to look after, but it doesn't run in Spain.

What to check first

• Whether Spain is really the requirement. A Spanish public tender may ask for an ENS-certified cloud, and some contracts name a country. Many others only ask for the EU. Find the exact wording before you narrow your options to Spanish data centres.
• Who you sign with. A Madrid region of a US cloud keeps the servers in Spain, but your contract is with a US group. Read EU region vs EU company if that distinction matters to your customers.
• How much you want to run yourself. A VPS or a bare-metal server gives you a machine. Patching, deploys, TLS and backups stay with you unless you buy a managed layer on top.
• Certificates you'll be asked for. For the Spanish public sector, that usually means ENS at Medium or High. The ENS guide covers what each level needs.
• The database. If you need managed Postgres beside your app, check that the provider sells it in the same Spanish location.

1. Clouding.io

Clouding.io is run by Cloudi NextGen S.L., registered in Barcelona. Its platform sits in the industrial area of Barcelona, and its IP addresses geolocate to Spain. Servers use KVM, with storage replicated three times in a Ceph cluster, and you can start from images that include Docker, WordPress or control panels such as Plesk.

• Best for: developers who want a small Spanish VPS with hourly billing and no monthly minimum.
• Price: from €0.004 an hour, capped at €3 a month, for half a vCore, 1 GB RAM and 5 GB NVMe, excl. VAT. 4 TB of transfer a month is included. New accounts get €5 of credit.
• What it lacks: a deploy pipeline. It's a virtual server, so you install the runtime and ship code to it yourself.

2. Arsys

Arsys Internet S.L.U. is based in Logroño, La Rioja, and its legal page places it in the IONOS group. It sells cloud servers hosted in a Spanish data centre, and its Logroño facility holds a Tier III certification from the Uptime Institute. You can add managed PostgreSQL and MongoDB, object storage and Kubernetes to a server. The same legal page lists a certificate of conformity with ENS.

• Best for: Spanish companies that want a local provider with servers, databases and Kubernetes under one contract.
• Price: cloud servers from €5.04 a month for 1 vCPU, 2 GB RAM and 50 GB, calculated over 30 days, VAT not included.
• What it lacks: a documented way to deploy a web app from a Git push. You build on its servers or on Kubernetes.

3. Stackscale

Stackscale started in Amsterdam in 2012, launched in Spain in 2013 and has been part of Grupo Aire, a Spanish connectivity and cloud group, since 2022. It runs three data centres in Madrid and two in Amsterdam, and Grupo Aire adds sites in Alicante, the Canary Islands, Málaga, Toledo and Valencia. Its data centres are certified to ISO 27001 and ISO 22301.

• Best for: companies that need dedicated hardware or a private cloud in Madrid, with support around the clock.
• Price: compute nodes from €395 a month with a €395 setup fee, taxes not included. Other configurations are quoted on request.
• What it lacks: self-service app hosting. It's infrastructure for teams or integrators that run their own stack.

4. AWS, Google Cloud and Azure in Spain

All three big clouds have a Spanish region. AWS lists eu-south-2 with three availability zones in Spain, and you must opt in before you can use it. Google Cloud's europe-southwest1 region sits in Madrid, and Azure's Spain Central region is also in Madrid. Each states ENS High certification for named services, as the ENS guide sets out.

• Best for: teams already on one of these clouds, or public-sector projects that need an ENS High cloud in Spain.
• Price: billed by use, with a separate price for each service.
• What it lacks: an EU parent company. You also wire up builds, networking and deploys yourself unless you add their managed app services.

5. UpCloud

UpCloud is a registered Finnish company with a data centre in Madrid alongside Amsterdam, Copenhagen, Frankfurt, Helsinki, London, Stavanger, Stockholm and Warsaw. It sells cloud servers and managed MySQL, PostgreSQL, Valkey and OpenSearch.

• Best for: teams that want an EU-owned cloud with a Madrid location and managed databases.
• Price: hourly, see its pricing page.
• What it lacks: a Spanish company behind it, if your buyer asks for one.

6. Eurobase

Eurobase fits when the EU is enough, because it doesn't have servers in Spain. It's a business registered in Warsaw, Poland, running on European infrastructure operated by Scaleway, a French provider. You connect a repository on GitHub, GitLab, Codeberg, Forgejo or Gitea and each push deploys. Next.js, Astro, Nuxt and similar frameworks run on V8 isolates, and Node.js, Python, Go, Java, Ruby, PHP and .NET servers run as containers. Coding agents can deploy through its MCP server and CLI.

• Best for: Spanish founders and agencies who need EU hosting for a web app, without running a server.
• Price: free to start, with Starter at €10 and Pro at €20 a month + VAT for each workspace. There are no usage charges today: work over a limit is refused, apps on V8 isolates and Functions stop until the monthly reset, and containers and static sites keep serving.
• What it lacks: a Spanish location, an ENS certificate, managed Postgres, MySQL or Redis, preview deployments and Dockerfile builds. Its ISO 27001 and SOC 2 audits are under way, so neither certificate can be shown to a buyer yet.

The host in the EU guide shows where each part of a Eurobase app runs.

How to choose

• You need servers in Spain at a low monthly price: Clouding.io.
• You want a Spanish provider with managed databases and an ENS certificate on file: Arsys.
• You need dedicated hardware or a private cloud in Madrid and can budget a few hundred euros a month: Stackscale.
• A Spanish public tender at ENS High, or a team already on a hyperscaler: the Spanish region of AWS, Google Cloud or Azure.
• An EU-owned cloud with a Madrid site and managed Postgres: UpCloud.
• An app that must stay in the EU but not inside Spain, deployed from Git with no server to manage: Eurobase. See also hosting for European startups.

Frequently asked questions

Do I have to host my app in Spain to comply with GDPR?

No. GDPR is an EU regulation, and it doesn't single out Spain as the place your data must live. A contract, a sector rule or a public tender can still name Spain, so check those documents. Data residency vs data sovereignty explains the difference between where data sits and who controls it.

Which cloud providers have a data centre in Madrid?

Google Cloud and Microsoft Azure both run a region in Madrid, Stackscale runs three data centres there and UpCloud lists Madrid among its locations. Exoscale, a Swiss provider, lists a Madrid zone in Alcalá de Henares as upcoming.

Is there a Spanish alternative to AWS?

For servers, yes. Clouding.io and Arsys are Spanish companies with Spanish data centres, and Arsys adds Kubernetes, object storage and managed PostgreSQL and MongoDB. Neither offers the full range of AWS services, so list what your app uses before you move.

What's the cheapest way to host a small app in Spain?

Among the providers here, Clouding.io lists the lowest entry price, a VPS capped at €3 a month excl. VAT. You'll still have to set up and maintain the server. If the EU is enough, Eurobase has a Free plan with hard limits.

Do I need an ENS-certified host?

Only if your system serves a Spanish public body and the contract puts it in scope. At Medium or High, the cloud under your system must be certified too. Read What is ENS before you pick a provider for that work.
