The A12 AI Low Code Platform
Strengthens the Deutschland-Stack

True digital sovereignty from Germany – the open source low-code platform,
proven in production by tax and state administrations.

Sovereignty is the goal.
The A12 AI Low Code Platform makes it achievable.

The Deutschland-Stack creates the sovereign, interoperable digital infrastructure for federal, state, and municipal governments. This requires building blocks that seamlessly support these goals:

Open, independent, proven, and from Europe.

The A12 AI Low Code Platform is exactly that kind of building block. A freely available strategic platform for digitizing government services, proven at the scale of more than 50 million tax returns annually and in the replacement of over 100 legacy applications in a state administration.

Schleswig-Holstein state is accelerating the phase-out of Microsoft Access and the development of modern administrative applications with the A12 AI low-code platform

With the concept of model-based software development (low-code approach) and the use of the A12 platform, the state administration is enabled to provide software solutions both with external support and independently. This results in modern, web-based procedures that meet current needs and   are secure. Furthermore, the results can be made available to other local authorities across Germany for reuse.
"We are deliberately focusing on digital sovereignty through open-source solutions, on nationwide reusability of these solutions, and on transparency."
Dirk Schrödter, Head of the State Chancellery of Schleswig-Holstein

The A12 AI Low Code Platform
in the Deutschland-Stack Criteria Check

The Deutschland-Stack is built on six criteria –
A12 meets all six:

Digital Sovereignty

A12 offers portability at both the vendor and model level, open source, and open interfaces. Around 7.5 million lines of code are openly available, with production and development taking place in Germany. The public sector retains control over data, architecture, and operations. The requirements of the ZenDiS Sovereignty Check are met on a sustained basis.

Your advantage: No vendor lock-in - complete freedom thanks to open source.

Interoperability

A12 integrates into existing IT infrastructure rather than replacing it. API-first, modular, open architecture, auditable code, clear interface standards – designed for municipal data centers, the German Administrative Cloud, and the OZG-Cloud.

Your advantage: Existing systems stay in place rather than being replaced.

Future-Proofing

The domain logic stays in the hands of the administration, separate from the technology – A12 domain models have outlasted multiple generations of web technology without being rebuilt. AI operates in a controlled and transparent manner on explicit models, in compliance with the EU AI Act.

Your advantage: State-of-the-art technology without the need for new technical developments.

Market Relevance

A procurable product from Germany, in production for years – deployed in tax administration (KONSENS), in OZG application portals, in the Access replacement project in Schleswig-Holstein, in online services, and in other areas. Implementation and operations are carried out by the administration itself, supported by mgm or certified A12 partner companies.

Your advantage: A proven solution tested in production.

Trustworthiness

A12 is proven in continuous operation of security-critical procedures serving millions of users. BSI baseline protection requirements are embedded in the development process; accessibility according to BITV 2.0 and WCAG is built into the platform. Digitally sovereign solutions are of strategic importance to mgm.

Your advantage: Stable foundation for collaboration, sovereignty, and long-term partnership.

Sustainability

Domain modeling and low code are ideally suited for digitizing administrative processes. Open standards and open source promote reusability (EfA principle). Deutschland-Stack requirements are already being taken into account today.

Your advantage: Professional models in open, reusable formats.

A12 Has Proven Itself for Years

A12 is embedded in public administration – in a state administration, in the nationwide self-governance of a professional association, and in Germany's largest tax procedure.

Deutschland-Stack Implementation for
Public Administration – with A12

The Deutschland-Stack's platform core bundles five base services for which the federal and state governments agreed on mandatory integration in June 2026.
A12 — The Five Base Services (embed)
Log In
Identity and Trust
DeutschlandID and EUDI-Wallet authenticate users. A12 applications add roles and permissions.
Submit
Data Exchange
FIT-Connect transmits applications and responses. Already available today via the OZG Cloud.
Verify Evidence
Data Retrieval
NOOTS securely retrieves evidence from registries. Foundation of the Once-Only principle.
Pay Fee
Payment Processing
ZBDS and ePayBL are the central payment services. The specialized procedure triggers the payment.
Decision and Feedback Channel
Mailbox and Notification
ZaPuK is the target architecture for mailbox and communication.
The Deutschland-Stack will be built through 2028, the EUDI-Wallet launches in early 2027, and NOOTS implementation has only just begun. Specialized procedures are not starting from scratch – transitional solutions and sound concepts are needed.

A12 applications are architecturally prepared for this: because domain logic and integration are separated, an interface can be swapped out without rebuilding the procedure.

Act Now with the Deutschland-Stack in Mind
mgm guides you through this transition – with experience from replacing legacy procedures, with expertise in the federal IT landscape, and with solution concepts within the technology landscape of the Deutschland-Stack. With A12 as the foundation, these requirements can be implemented step by step and precisely tailored.

Questions and Answers
on the Deutschland-Stack

When will the Deutschland-Stack be available?

+

It is being built incrementally through 2028. The federal and state governments agreed on binding standards and the use of central components in March and June 2026. Even though many details are still being worked out and standardization is not yet complete, the public administration is able to act. Projects should plan for future requirements and use transitional solutions in the meantime. BMDS timeline

How is German public administration preparing for the Deutschland-Stack?

+

Start with a real specialized procedure rather than a concept: describe the domain logic in open models, set open source as the standard, and plan for integration with eID, FIT-Connect, and the payment service from the outset. The domain knowledge remains within the administration and can be transferred to the next procedure, even as interfaces and technology change.

Which technical components are mandatory in the Deutschland-Stack?

+

Five base services (resolution of June 17, 2026): Identity and Trust (eID, EUDI-Wallet, BundID), data exchange via FIT-Connect, data retrieval via NOOTS, the central payment service, and the central mailbox. Existing standards such as XOeV and FIM are also included. The OZG Cloud already provides solutions for data exchange in municipal administration today.

What does the Germany Architecture require?

+

The federal government's architecture requirements are binding and guide the selection of components. For specialized procedures, the most relevant requirements are API-first design, reusability, European origin, and end-to-end processing throughout.

What is the DeutschlandID?

+

The federal government's central citizen account. Under Section 12 of the OZG, the current BundID is to be developed into the DeutschlandID and integrated into the EUDI-Wallet by 2027; plans include bidirectional communication via mailbox. For specialized procedures, this means: identity and the feedback channel come centrally, while the domain processing stays within the procedure. Overview of BundID and DeutschlandID

What is the Sovereignty Check?

+

A criteria catalog by ZenDiS that evaluates organizations – not individual products. Criteria include applications, data, operations, and the capability development of the organization's own staff. A12 meets these criteria extensively and facilitates the implementation and operation of digitally sovereign solutions.

What is the Service Standard?

+

Binding quality requirements for government online services, specified in DIN SPEC 66336 – covering user analysis, accessibility, security, and reuse. About the Service Standard

What does open source mean for procurement?

+

Following the reform of the EVB-IT standard contracts in March 2026, open source is the default for new developments. Anyone offering a closed solution must provide justification. For A12, three procurement paths are available: the federal framework contract, reuse via a public IT service provider, or direct procurement via the open license.
