EU Hosted Backend as a Service: How to Choose One

An EU hosted backend gives you a database, authentication, file storage and server functions running in European data centers, so personal data of your users stays in the EU by default. The options fall into three groups: global platforms with EU regions (for example Supabase or Firebase), EU-based providers that only run in Europe (StitchDB is one), and self-hosting an open-source stack on EU servers. Which fits depends on how strict your residency needs are, where your users are, and how much infrastructure you want to run.

This guide explains what "EU hosted" should cover, compares the three groups, and gives a checklist for evaluating any provider.

#Why teams want an EU backend

The reasons are usually some mix of:

• Customer requirements. B2B customers in Europe, especially in the public sector, health and finance, increasingly ask where data is stored and which companies can access it.
• GDPR transfer rules. Keeping data in the EU avoids relying on transfer mechanisms. The current EU-US Data Privacy Framework (adopted July 2023) replaced two earlier frameworks that courts struck down. For background, see GDPR-Friendly Database Hosting.
• Latency. If your users are in Europe, a backend in Europe is simply faster for them.

#What an EU hosted backend should cover

A backend is more than a database. Ask where each part runs:

A provider that keeps the database in Frankfurt but runs functions on a global edge network or logs in another region may still meet your needs, but you should know about it.

#Option 1: Global platforms with EU regions

Most large backend platforms let you choose a European region at project creation.

Supabase. As of November 2026, Supabase's regions page lists Ireland, Paris, Frankfurt and Stockholm in the EU, plus London and Zurich, which are in Europe but not EU member states. Supabase notes that its general "Europe" option may deploy to any available region in the area, so it is not suitable for a strict jurisdiction requirement; choose a specific EU region instead.

Firebase. Firebase and Google Cloud offer European locations for many services; check each product's locations page, because products have different location options.

Strengths: mature platforms, large ecosystems, global regions if you also serve other continents. Weaknesses: the providers are US companies, which some customers or legal teams treat as a risk regardless of where data sits, and some platform services may run outside your chosen region.

#Option 2: EU-based providers

These are companies whose infrastructure is in Europe.

StitchDB runs in its own European data centers: Falkenstein and Nuremberg in Germany, and Helsinki in Finland. Each project has a dedicated Postgres database plus Auth, auto-generated REST and GraphQL APIs, Realtime, Storage, Edge Functions and app services such as cron, queues and push. Per the docs and pricing FAQ, files are stored in EU object storage, backups are encrypted and kept in the EU, and logs are stored in EU object storage encrypted with AES-256. You pick the region when creating a project, and it cannot be changed later.

StitchDB speaks the same APIs as the open-source Supabase stack (PostgREST, GoTrue-style Auth, Storage, Realtime, Deno Edge Functions), so supabase-js and the other Supabase client libraries work by changing the URL and keys. There is an import wizard for Supabase projects and for any Postgres 12+ database. See Compatibility.

The trade-offs are real:

• EU-only regions. If a large share of your users are in the Americas or Asia-Pacific, they will see higher latency. Read replicas help reads but writes always go to the primary.
• Younger platform. Fewer third-party guides, integrations and community answers than the large platforms.
• No self-hosted edition. You use StitchDB as a service. Accounts the team enables can run projects on servers they own, managed by StitchDB, but there is no package to run the platform yourself.

#Option 3: Self-host an open-source stack on EU servers

You can run Postgres plus an open-source backend stack on servers you rent from an EU hosting company.

Strengths: full control over location, versions and access; no platform fees. Weaknesses: you own backups, point-in-time recovery, upgrades, security patches, monitoring, scaling and on-call. For a small team, that operational load is often larger than it looks.

#Summary

#Latency: a quick reality check

Where your app servers run matters as much as where the database runs. Every database query from an app server in Virginia to a database in Germany crosses the Atlantic. A page that makes ten sequential queries pays that round trip ten times.

Rules of thumb:

• Put app servers in the same region as the database.
• If clients talk to the backend directly (browser or mobile app calling the REST API), the latency is between the user and the backend, so an EU backend is ideal for EU users.
• For read-heavy global audiences, replicas closer to users help. StitchDB routes GET requests on its REST API to the nearest healthy replica when one is clearly closer; see Read replicas.

#A buyer's checklist

When evaluating any EU hosted backend, ask:

1. Where exactly are the data centers? Country and city.
2. Is the region fixed per project? Can anything move data out of it without your action?
3. Where are backups, replicas, files and logs stored?
4. Who are the sub-processors? Is there a published list and a DPA? StitchDB publishes a DPA and sub-processor list.
5. How is data encrypted in transit and at rest? On StitchDB, Postgres connections require TLS 1.2 or 1.3, and backups use AES-256. See Security.
6. What backup and recovery is included? On StitchDB, point-in-time recovery is on every plan: 24 hours on Free up to 30 days on Enterprise. See Backups.
7. Can you export everything in open formats? StitchDB's export gives you a pg_dump, auth users, files and settings in one archive on every plan.
8. What do costs look like at scale? Does the platform have a spend cap? See How to Avoid Surprise Backend Bills.
9. What happens if you leave? Is the API standard enough that you can move?

#Pricing at a glance

StitchDB plans, as of November 2026: Free ($0, 500 MB database, 1 GB files, 50,000 monthly active users), Pro ($15.99/month, 10 GB database, 100 GB files, 100,000 MAU), Scale ($49/month, 20 GB database, 250 GB files, 200,000 MAU) and Enterprise ($329/month). Paid plans start with the spend cap on, so usage stops at the included amounts instead of billing more. Full details on pricing.

#FAQ

#Is an EU region of a US provider good enough for GDPR?

Often, yes, combined with a DPA and the Data Privacy Framework or Standard Contractual Clauses. Some customers and legal teams prefer an EU-based provider anyway. Decide with your privacy lead.

#Can I use an EU backend for users worldwide?

Yes. Users far from Europe will see higher latency. Read replicas reduce it for reads.

#Can I move my existing backend to an EU provider?

If it is Postgres-based, usually yes. StitchDB imports Supabase projects and any Postgres 12+ database with a live copy; see How to Migrate from Supabase to StitchDB.

#Does EU hosting make my app GDPR compliant?

No. It helps with data location and transfers. You still need lawful bases, security, retention and processes for access and deletion requests.
