Bring your legacy applications to the web

With our conversion tools, you can extend the life of your legacy application by automatically converting it to HTML5 / JavaScript / WebAssembly.

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.

Converting vs Rewriting


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.


Web as a platform


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


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


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.
