Transform your desktop
apps into
fast, capable
web applications.
Reuse your existing code, avoid complex and costly rewrites, and ship 3x faster. Partner with our team of world-class WebAssembly experts to accelerate your modernisation journey.
The web has eaten the world.
The web has taken over. Your users expect instant access, modern UI, and zero friction — the unbeatable convenience of a link.
Desktop-bound software is a relic of the past: slow to install and update across your user base, costly to maintain across platforms, and a source of friction for the modern user.
Clinging to legacy systems hampers innovation and slows you down.
We help businesses go web-native, fast.
Leverage your existing code, don't start from scratch.
Rewriting your entire desktop application for the web is a risky, expensive gamble. It’s slow, introduces new technical debt, and often fails outright.
Instead of starting from scratch, we use WebAssembly (Wasm) to enable your existing battle-tested code to run on the web, preserving behaviour, avoiding new bugs, and getting your app working faster.
A smarter way to embrace the web.
Move faster, reduce risk, and secure your app's future.
Behaviour Consistency
Retain the same business logic and application behaviour as the original, ensuring a 1:1 match without any additional effort.
No Costly Rewrites
Reuse your existing source code and bring your application to all platforms through the web, without rewriting or redeveloping from scratch, saving both time and costs.
No New Technical Debt
Porting an existing battle-tested codebase minimises the risk of introducing new bugs or design flaws, and leverages all the debugging effort that has been invested in the existing code.
Faster Time to Market
Since you’re reusing most or all of your existing code, the development, testing, and debugging effort is substantially reduced. This results in a faster, more predictable timeline for launching a modernised product.
Performance and Security by Default
Wasm’s superior performance and security by design deliver a more efficient and secure user experience right out of the box, compared to a JavaScript rewrite, or a client/server model.
Lower Operational Costs
Since Wasm runs entirely client-side, it requires no costly server infrastructure. Compared to a client/server implementation, the savings in operational costs over time are substantial.
Flexibility and Compatibility
Port applications written in C/C++, Java, .NET, and more, with the result running seamlessly in all major browsers and OSes.

Your fast track to web-native.
Our team of world-class WebAssembly experts will work with you every step of the way, from initial assessment to deployment. Our process optimises for minimising risk at every step, delivering tangible results early and often.
Assessment
We analyse your software to understand its architecture and define a clear path to modernisation.
Proof of Concept
We build a PoC to test feasibility, assess risks, and refine the approach before full implementation.
WebAssembly Porting
We convert your legacy desktop code into a web-compatible format using WebAssembly for peak performance.
UI/UX Improvements
We enhance the UI and functionality to ensure a smooth, modern, and intuitive web experience.
Testing & Optimisation
We rigorously test and optimise your app across platforms to ensure flawless performance everywhere.
Deployment & Support
We launch your modernised app and provide ongoing updates and support to keep it running smoothly.
Real results, validated at scale.
Trusted by enterprise teams to bring large, complex apps to the web, delivering performance, reliability, and scalability by default.
Customer Stories
Our process and technology has been proven at enterprise scale, with millions of lines of code running in production today.
Taking a CPQ Application From PoC to production 70% faster
We ported over 200,000 lines of C++ to WebAssembly, for our client, a major multinational medical technology company. The effort was completed 70% faster than the initial timeline for a full rewrite.
Bringing 3D space planning to the web with Wasm
Using WebAssembly, we helped HomeByMe deliver the full power of their desktop app in the browser, including real-time 3D rendering, with near-native performance and full feature parity.
Broad language expertise, developed in real-world codebases.
We partner with teams maintaining mature desktop applications in C/C++, Java, and other widely used languages. We have extensive expertise with best-in-class tooling for porting C/C++ (using Cheerp) and Java (using CheerpJ) codebases to WebAssembly.
We also help teams navigate modernisation of applications written in .NET, Python, and other languages, assessing feasibility and performance tradeoffs on a case-by-case basis.
Deep industry knowledge. The best tools in the world.
We are a team of highly specialised software engineers who love tackling complex software challenges head-on. We’ve been using WebAssembly for over a decade; long before it became a standard. Our expertise has helped large enterprises and government agencies harness WebAssembly's speed, security, and flexibility to power next-generation web applications.
DRS Software is a proud service partner of Leaning Technologies, a world leader in cutting edge WebAssembly tooling. Together, we use the best tools available in the market to deliver rapid and cost-effective software modernisation with WebAssembly. Leaning Technologies’ WebAssembly solutions power large-scale deployments at government agencies, fortune 500 companies and academic institutions today.
With the right tools, WebAssembly makes porting faster, safer, and more reliable. In this space, Leaning Technologies sets the standard.

Frequently Asked Questions
How much of our existing codebase can realistically be reused?
In most cases, the vast majority of of your existing code can be reused. We'll evaluate your current software to identify the best approach for porting it to the web using WebAssembly, while rewriting or adapting it as minimally as possible.
What kind of cost savings can we expect compared to a full rewrite?
Porting to WebAssembly is far more cost-effective than a complete rewrite. By reusing your existing code, we reduce development time, eliminate the need for rebuilding functionality, and significantly cut costs associated with redevelopment.
Will the web version behave exactly like the desktop version?
Yes, we ensure that the web version matches the behaviour and performance of the desktop version. WebAssembly allows us to preserve your app’s functionality with minimal changes, so your users experience a seamless transition.
Can we keep supporting our current desktop users during the transition?
Yes, we can implement a phased rollout of the web version while still supporting your desktop users. With WebAssembly, you can continue building the same codebase for both desktop and web, ensuring business continuity and making the transition smoother for your users. You might even consider supporting both versions long term, and WebAssembly makes this easy by sharing a single code-base.
What are the limitations of using WebAssembly in the browser?
WebAssembly is a powerful tool, but there are some limitations, such as restricted access to certain system resources (e.g. files). During our porting process, we recommend and implement replacement functionality for features that require access to the underlying system. More generally, Wasm's limitations often result in an improved and more secure application.
How will performance compare to the native version?
WebAssembly provides near-native performance in the browser, making it an excellent choice for high-performance applications. It will typically perform as well as or better than traditional JavaScript-based solutions.
How do updates and deployment work once we’re web-based?
Once your app is ported to the web, updates and deployments are much easier. Web-based applications can be updated instantly for all users, ensuring your app stays current with minimal effort from your side.
What’s the typical timeline for a project like this?
The timeline depends on the complexity of your app, but porting to WebAssembly is typically significantly faster than a full rewrite. We provide a clear roadmap and timeline to ensure the project is completed efficiently and on time.
Will our internal developers be able to contribute after the port?
Yes, your existing developers can continue contributing to the project after the port. They can work with the same codebase and tools they are familiar with, making the transition seamless and allowing for ongoing development.
How do we get started and what does a proof of concept involve?
We start with a no-commitment proof of concept (PoC) to assess the feasibility of porting your app to WebAssembly. If you’re happy with the results, we’ll proceed with the full project. If not, there’s no obligation to continue.
