EU Stack Check

EU Stack Check: assess your software dependency

Select the tools you use today. Euro Toolhub shows where strong dependencies exist, which European alternatives realistically fit and which switches make sense first.

The EU Stack Check is editorial orientation. It does not replace a data-protection, legal or IT-security review.

What is the EU Stack Check?

The EU Stack Check is a free tool that shows how strongly your current software stack depends on providers outside the EU and EFTA. You select the tools you use today – from cloud and analytics to office, email, AI, CRM and developer tools. The result is an EU stack score, your strongest dependencies, quick wins and an honest tool-by-tool assessment with matching European alternatives.

Why software dependency can be a risk

Running core processes on providers outside the EU makes you dependent on their pricing, product and legal decisions. Added to this are questions about data transfers to third countries, the US CLOUD Act and digital sovereignty. This does not mean every non-EU tool is a problem – but it helps to know where concentration risks exist and which switches are realistic.

Which categories are checked

The check covers common building blocks of a modern stack: web analytics & tracking, cloud & hosting, office & collaboration, email & calendar, file storage & sharing, communication, CRM & sales, marketing & newsletter, project management, payments, e-signature, forms & surveys, developer tools, auth & identity, AI & LLMs and support & helpdesk.

How the EU stack score is calculated

Each selected tool contributes a penalty based on its dependency level (low, medium, high, critical). The score is 100 minus the average penalty of your selected tools and ranges from 0 to 100. We also estimate your improvement potential based on how many of your tools can be replaced with low to medium effort. The score is deliberately simple and transparent and is editorial orientation, not a certification.

Why not every European alternative is a 1:1 replacement

This is the tool’s most important rule: a European alternative can replace a tool fully, only partially, only for individual base services or not at all. Hetzner, for example, is a sensible European option for virtual and dedicated servers and simple storage – but it does not replace the entire AWS ecosystem with serverless, managed databases, IAM, queues, analytics and marketplace. That is why we label the replacement scope and recommendation strength for every alternative and state openly where our directory does not yet have a suitable option.

Frequently asked questions

What does the EU Stack Check measure?
It measures how strongly your selected software stack depends on providers outside the EU and EFTA, and shows European alternatives with their replacement scope and migration effort.
Is the score legal advice?
No. The score is editorial orientation based on public information and does not replace a data-protection, legal or IT-security review.
Does European software automatically mean GDPR-compliant?
No. A European headquarters is one factor but not a guarantee. Whether a deployment is GDPR-compliant depends on the contract, configuration and processing in each case.
Why can't AWS simply be replaced by Hetzner?
Hetzner can cover base services like virtual and dedicated servers or simple storage. But AWS is a very broad ecosystem with serverless, managed databases, IAM, queues, analytics, AI services and marketplace that no single provider replaces automatically.
Which tools are easiest to replace?
Often web analytics, newsletters, email, video conferencing and file storage – here strong European alternatives exist with mostly low to medium switching effort. The tool marks these as quick wins.
Can I suggest providers?
Yes. Where our directory does not yet have a suitable alternative, you can submit a suggestion via “List a provider”.
How current is the data?
The assessments are based on publicly available provider information and are maintained editorially. They are not independently verified; details can change.
