Qt modernisation:
free, AI-powered audit
free, AI-powered audit
Find out exactly what’s in your Qt codebase, what it’s costing you, and what modernisation would take. AI agents run the analysis. Qt engineers validate every finding. No cost, no obligation.
Most teams with legacy Qt code know something needs to change. They just don’t know the scope, the risk, or the price tag. This review gives you all three, in a day.

Your Qt codebase is carrying more risk than you think
Legacy Qt projects rarely fail all at once. They slow you down gradually, and the costs stay hidden until something forces the issue.
Technical debt compounds with every sprint
Deprecated APIs and tightly coupled architecture mean every new feature takes longer than it should. The codebase that felt manageable two years ago is now a drag on every sprint.
Qt 5 is end-of-life
No new security patches. No bug fixes. Any Qt security vulnerability discovered now stays open, and your exposure grows with every month you remain on an unsupported version.
EU Cyber Resilience Act, December 2027
The CRA requires secure-by-design products across the EU market. Legacy Qt code may block compliance, and Qt SBOM generation and CRA readiness checks take time to get right. Starting now is significantly cheaper than starting in 2027.
The cost of not knowing
The biggest problem isn’t the technical debt itself. It’s that most teams don’t have a clear picture of what they’re dealing with, so they either underestimate the work or avoid the conversation entirely.
What’s included
The free audit tells you what modernisation would cost and how long it would take. Whether you act on it immediately, plan it into next year’s roadmap, or simply want to understand what you’re working with, that’s your call.

Specialised agents cover security vulnerabilities, dependency mapping, implementation quality, and code health, using clang-tidy, clazy, qmllint, and more. Qt concurrency bug detection runs as part of the security pass. The analysis completes overnight.
Qt engineers validate the findings
Our engineers review every AI-generated finding before it reaches you. What you receive isn’t raw output; it’s a prioritised report with context, effort estimates, and a recommended migration path.
Why Spyrosoft is the right partner for Qt modernisation
Qt Premium Partner
Direct access to Qt engineering, pre-release software, and a qualified toolchain for ISO 26262 work. Not a badge; a working relationship that makes a practical difference on complex projects.
AI-augmented delivery
We built our own audit agent infrastructure specifically for Qt codebases. The same tooling that powers the free review is what we use in production migrations. It’s not a prototype.
Production work across automotive, marine, and consumer electronics
Our Qt and QML migration consulting spans automotive HMI, marine navigation systems, consumer electronics, and industrial interfaces. The Thermomix TM7, hydrogen refuelling units, smart home panels. These are production products, not portfolio pieces.
Engineers, not account managers
Przemysław Krzywania, our HMI and Consumer Electronics Director, runs these reviews personally. When you get on a call with us, you’re talking to someone who has shipped Qt code.

Meet our experts
Passionate about daily human and machine communication, I take care of the development of the HMI area and empower Spyrosoft teams to stay at the forefront of this dynamic field. With a strong background in both technical and managerial positions, I know how to translate business needs into an appealing and functional product that elevates the experience of an end customer.
I’m a firm believer in the cultural ramifications of user-focused design in technology.
Throughout my career, I have led teams in developing modern products on a multitude of software and hardware platforms. The knowledge of HMI architectures and C++/C#/Java and Python languages, has allowed me to work with OEMs and TIER1s on the next-gen production HMI platforms.
With my motivation of building tomorrow’s digital society, I’m is mainly responsible for shaping the technology definition and vision of HMI Services at Spyrosoft.
I use the experience I have gained in twenty years of work to design interfaces for HMI. I highly value simple solutions to complex problems.
In my work, the most important thing is to diagnose and understand the problem, listen to the stakeholders and propose a solution that meets the established criteria.
I especially appreciate the substantive support of programmers, thanks to which our projects move easily to the implementation stage, which allows us to quickly test our hypotheses.

FAQ
Qt 5 no longer receives security patches.
Every new vulnerability discovered in Qt 5 stays open. No fixes, no backports. Your product is exposed to risks the framework stopped addressing long ago.
The cost of every new feature keeps growing.
Deprecated APIs, tightly coupled architecture, C++ Widgets without proper separation of logic and UI. Every change takes longer than it should. This is not technical debt you can work around — it is a cost that compounds with every sprint.
Concurrency bugs in legacy code are hard to find but easy to exploit.
In a typical automotive HMI project on Qt 5, our agent found 9 concurrency bugs and 10 data race conditions across 13 files. This class of vulnerability is invisible in code review but well understood by attackers.
New engineers do not want to work with a legacy stack.
Qt 5 with C++ Widgets is a stack every junior developer has to learn from scratch. Qt 6 with QML is an environment where you can hire from the market. Maintaining old code carries hidden recruitment and onboarding costs that never show up in a sprint estimate.
Qt 6 unlocks capabilities you are currently paying for but cannot use.
Hardware acceleration, Qt Quick 3D, multi-display support, better GPU integration — these are features covered by your licence that remain out of reach as long as you are on an older version. Migration is not just a compliance exercise. It opens product options.
Migration after the deadline costs significantly more.
Every new feature you build on Qt 5 today adds to the migration scope later. The longer you wait, the larger the codebase that needs to move. Scope grows linearly with time, and the window before the CRA deadline is closing.
No SBOM blocks sales in the EU.
Qt 6.8 LTS delivers SBOM in standard formats. Qt 5 does not. If a customer or acquirer asks for a software bill of materials for your product components, Qt 5 leaves you with nothing to show.
Legacy maintenance ties up your most experienced engineers.
It is not juniors who maintain old code. It is the seniors who understand it. Every hour spent debugging deprecated APIs is an hour not available for new product architecture.
Yes. No hidden fees, no minimum engagement, no pressure to proceed. You get the report regardless of what you decide to do with it.
Read access to your repository. That’s it. We handle the rest and deliver the report within 24 hours of receiving access.
The AI agents are built for exactly that. Large, complex codebases are where the Qt codebase audit is most valuable, because the scope of modernisation is hardest to estimate manually.
No. The report is yours to use however you choose: take it to your internal team, use it to scope work with another partner, or come back to us when the timing is right.
If you sell software-containing products in the EU market, the CRA requires secure-by-design practices by December 2027. The compliance section of your report covers CRA readiness and SBOM requirements specific to your codebase.
Particularly so. Knowing the scope and cost of a Qt5 to Qt6 migration early, before deadline pressure arrives, gives you options. Teams that wait until 2027 won’t have them.
The CRA is an EU regulation adopted in December 2024. It applies to every product containing software that reaches the European market — from IoT devices and industrial HMI to consumer electronics.
Two dates that matter:
September 2026: the vulnerability reporting obligation comes into force for products already on the market. If your product is sold in the EU, from this date you are required to report actively exploited vulnerabilities.
December 2027: full compliance required for all new products. Secure-by-design, documented vulnerability management, CE marking with a cybersecurity component, SBOM in a standard format.
What this means for Qt code:
Qt 5 is end-of-life. New CVEs are not addressed by the Qt Group. A product built on Qt 5 does not meet the secure-by-design requirement because it depends on a library with no active security maintenance. This is not an interpretation — it is the kind of finding that surfaces in an audit a regulator can request.
Qt 6.8 LTS provides up to five years of support and delivers SBOM in standard formats, which is a direct CRA requirement. Migrating to Qt 6 addresses both the EOL risk and the compliance gap in a single engagement.
Why timing matters:
Migrating from Qt 5 to Qt 6 in a typical embedded HMI project takes months. Factor in regression testing, validation, and staged rollout, and you are looking at a minimum of one quarter, realistically two to three. Teams that start in late 2026 will be working under deadline pressure with no buffer for problems. The cost of getting something wrong in that context is different.
What the report covers:
The CRA section of our audit includes a readiness assessment specific to your codebase: identified vulnerabilities mapped to CWE and CVE references, EOL dependency status, missing SBOM elements, and concrete recommendations you can hand to your legal or compliance team.
