The Problem
Europe Builds on Infrastructure It Doesn't Control
Every European app that uses Firebase, Supabase, Vercel, or AWS Amplify runs on a US-owned control plane. The data may live in Frankfurt, but the company that operates the platform, holds the keys, and answers subpoenas is a US corporation. In 2025 the consequences stopped being theoretical.
~70%
of Europe's cloud market is held by US hyperscalers[1]
~15%
is the combined share of all European cloud providers[1]
1 law
the US CLOUD Act reaches any US-owned provider, anywhere[2]
Foreign jurisdiction is not theoretical — 2025 made that clear
A US sanction, a global blackout[3]
February 2025: the US sanctioned ICC prosecutor Karim Khan. His official Microsoft mailbox went dark shortly after; the ICC subsequently moved to Switzerland's Proton Mail and by October 2025 dropped Microsoft 365 entirely. Whether Microsoft or the ICC pulled the plug, the sovereignty conclusion is the same.
Microsoft under oath: no guarantee[4]
In a French Sénat hearing (June 2025) Microsoft France conceded under oath that it cannot guarantee EU customer data stays beyond US government reach. The CLOUD Act's extraterritorial effect is unrepealed; a second Schrems case is on file at the CJEU against the 2023 Data Privacy Framework.
The CLOUD Act follows the flag, not the data[2]
Frankfurt or Dublin regions do not remove US jurisdiction. Any Firebase, Supabase, Vercel, Amplify, or Neon project remains subject to 18 U.S.C. §2703 subpoenas, FISA §702 collection, and executive orders — reviewable and revocable at any time by the same US authorities.
GDPR compliance you can't verify[5]
Schrems II struck down Privacy Shield in 2020. The 2023 Data Privacy Framework is a US executive order — its oversight board (PCLOB) lost its quorum in January 2025 when its Democratic members were dismissed. Your DPO needs a signed DPA, a live sub-processor registry, and a defensible RoPA. Most BaaS platforms hand you a template PDF and a support-portal ticket queue.
DSAR requests are a four-figure tax per case[6]
GDPR Article 15 gives every end-user the right to a copy of their personal data within 30 days. Building the export yourself — SQL joins across auth, storage, logs, plus PDF generation and legal review — runs 8-12 hours per request at a consultant's billable rate. Firebase, Supabase, and AWS Amplify give you a docs checkbox and a "DIY" tutorial.
No serious EU Firebase/Supabase alternative[7]
Bare managed Postgres from Scaleway, OVHcloud, or Aiven solves compute — not auth, not storage, not realtime, not edge functions, not DSAR export, not DPA paperwork. The developer-experience gap between "one platform, one SDK" and "assemble six services yourself" is why EU teams keep defaulting to the US stack even after Schrems II.
Every European team hits the same trade-off:
Choose world-class developer experience — and inherit US jurisdiction
Choose EU sovereignty — and rebuild your backend from six moving parts
Europe deserves both — on day one, on Free tier, on one SDK.

Automated DSAR
One click. Article 15 + 20. Built into every project.
When a user emails "what do you have on me?" (Article 15) or asks for their data on the way out (Article 20), Eurobase turns the answer into a one-click console export. No SQL to write each time. No middleware to maintain. The 30-day deadline stays statutory; the tooling stops being the bottleneck.
The cost of DIY DSAR
A single DSAR runs about $1,500 to fulfil — and request volume is up 246% in two years. That cost lands on whoever happens to be on call.

Every other major BaaS leaves DSAR fulfilment as homework. Custom SQL across every table, custom middleware, custom audit trail. Re-implemented per project.
| Platform | Built-in DSAR? | What you do instead |
|---|---|---|
| Firebase | ✗No DSAR primitive | DIY Cloud Function across Firestore collections + Auth + Storage |
| Supabase | ✗No DSAR endpoint | Hand-roll across auth.users and every public table |
| AWS Amplify | ✗No DSAR primitive | DIY across DynamoDB / Cognito / S3 buckets |
| Eurobase | ✓One click. Every project. Every tier. | Per-user export + full-project zip + audit trail — out of the box |
The Eurobase answer
DSAR is a first-class platform feature — not a checkbox in an enterprise tier, not a paragraph in the privacy policy. We built it because we got tired of watching small EU teams treat each request as a fire drill.
Article 15 + Article 20 in one click.
Per-user export (every row referencing their user_id) and full-project export (every table + auth + storage manifest) as a downloadable zip.
Audit log captures every request, completion, and failure.
Actor email + IP, stamped on every action. Your evidence trail is built in, not bolted on.
All bytes stay on Scaleway fr-par.
Zero CLOUD Act exposure. Download links expire after 7 days. EU jurisdiction end-to-end.
API stays open on every tier.
Free-tier projects can still meet a statutory deadline by calling the export endpoint directly — we won't paywall a legal obligation.

THE EU GAP
US hyperscalers control >70% of Europe's cloud infrastructure. There is no EU-native BaaS platform. Every major option — Firebase, Supabase, Amplify — is US-owned, US-hosted, and subject to the CLOUD Act.
EU-native BaaS platforms exist today

Thoughts on European data sovereignty, cloud infrastructure, and building for developers.
Which parts of your stack can a US authority legally reach? A 60-second check
We rated 112 SaaS vendors — Postgres providers, auth stacks, storage, email, analytics — on five separate dimensions each: corporate parent, data residency, operational access, subprocessor chain, transfer mechanism. The tool at /sovereignty-check lets you tick the ones you use and get a shareable exposure percentage back in about sixty seconds. Free, no signup. Here is what the tool does, what the data says, and where it fits in the flow.

A customer asks a small EU fintech for a copy of all the data they hold on him. Walk through the DIY workflow (SQL across a dozen tables, format, sign, log, audit) — then the same job on Eurobase (one click). Same legal outcome. 8-12 hours vs 30 seconds. Plus what happens two weeks later when the customer asks for the DPA and the sub-processor list.

If you want a managed Supabase-shaped backend that is EU-headquartered and hosted on EU-owned infrastructure — not just deployed to an EU region of a US hyperscaler — the shortlist is genuinely short. This is the honest 2026 comparison of the five options developers actually consider: Eurobase, Nhost, Appwrite, PocketBase, and self-hosted Supabase — with the axes that matter for GDPR and the queries where each one is the right answer.

A DPO asked me for our RoPA the other day. I opened Eurobase, downloaded the auto-generated Article 30 report, and sent it in 20 seconds. On most backends that request is a fortnight-long ticket. That gap is what the new /gdpr-readiness assessment measures — a free 10-question quiz that scores your current backend against the specific GDPR obligations most managed platforms leave as your homework.

Nothing headline-grabbing, but a bunch of papercuts we shiped in the last few days that should make daily use noticeably nicer. Console-uploaded files are now deletable and downloadable. Filenames with umlauts, spaces, or commas work. SMS auth got a security hardening pass. And the "Copy URL" button on storage actually gives you a shareable link now.

Today the doors open: sign up at console.eurobase.app, no invitation required, no credit card for Free.

A German legal-tech founder cannot ship the product without §203 StGB paperwork, §43e BRAO staff secrecy declarations, GoBD-conformant exports, and 10-year WORM retention.

Here is exactly what a Kanzlei-facing backend has to solve — what Eurobase already does today, and what is landing in the "Legal Team" tier over the next weeks.

You picked the eu-central-1 region, you signed the DPA, and the compliance page has a green tick. Under EU law — and under the CLOUD Act — that gets you less than most teams think.

Volume is up 246% in two years (DataGrail). Eurobase puts Article 15 export, RoPA, and a tamper-evident audit log on the Compliance tab of every project, by default.
