Migrate an application with our

compile-to-WebAssembly solutions

Compile to WebAssembly?

A next-generation language of the Web, compatible with any Browser and any Device, WebAssembly allows your code to breathe new life and be compiled into a standard Web application.

Extend the life of Legacy Apps

With our conversion tools, you can extend the life of your legacy application by automatically converting it to HTML5/JavaScript/WebAssembly. Whether Java, C/C++ or Flash, we have a solution for you.

Future proof your technology

Web Applications are growing in complexity, and gradually replacing the role of desktop applications. Thanks to WebAssembly and our tools, you can future proof your applications by bringing them in whole or in part to the Web.

WebAssembly Experts

At Leaning Technologies we specialise in bringing your software to the browser. Compiled automatically, executed efficiently, fully client-side. Our team of WebAssembly and compiler experts are ready to help you on your next project.

Who we work with

Core benefits

Converting vs Rewriting

Faster

An efficient, automated process with more certain timelines.

Single code base

Keeping a single code base means avoiding code duplication and maintenance costs in the future.

No bug duplication

Writing code results inevitably in the creation of new bugs and issues. Reusing existing code means avoiding it.

Leveraging existing skills

Avoid having to double your team, by keeping on the project the persons that already made it great.

Using technology instead of man-power, to reduce costs and uncertainties.

The idea

Web as a platform

Secure

Browsers isolate the operating system through sandboxing and gatekeeping. Computation executes client-side on devices, ruling out any breach during data transmission.

Standardized

No device- or operating system-dependent code to mantain. Targeting browsers allows to solve problems now and future-proof your application.

Fast

Browsers are exceptionally fast at executing code, and they keep improving. The WebAssembly standard is another big step in this direction, bringing browser applications close to native speed.

The performance and size of the converted code have been always quite impressive, but in the last year, Cheerp has further dramatically improved the runtime speed, and drastically reduced the compiled size, allowing us to save on bandwidth and resources, as well as to extend our customer base. As a matter of fact, the performance is so good that [...] we moved to a web-only application!

Our partnership with Leaning Technologies is a major resource for Blackbird, accelerating the development of the Blackbird editor in JavaScript editor by many months. This innovation ensures Blackbird will continue to provide best-in-class efficiency in video production workflows for the foreseeable future.

We believe CheerpJ is the most turn-key Java conversion project on the market. For larger conversions, we really recommend the supplementary development services offered by Leaning Technologies. Their highly skilled development team were able to fix quickly any problem we threw their way.
