Frequently Asked Questions

"Leaning" Technologies?

It's a not-well-concealed nod to the Leaning Tower of Pisa, Italy, where our founders met during University.

Leaning "Technologies"?

We are a technology-first company. Our team of compiler engineers and WebAssembly experts push the boundaries of browser technologies every day.

Why Web Browsers?

Web Browsers are ubiquitous, and very powerful, standard platforms for delivering applications. By creating tooling for the browser, we enable applications to be served to virtually any user, on any operating system, on any device.

Could I really bring X to HTML5?

Very likely. Modern browsers no longer suffer from the limitations they once had (slow JavaScript, limited APIs, etc). They can be used to bring virtually any application to the web.

What languages do you speak?

All of our solutions are written in C++. Our tools compile or virtualise to JavaScript and WebAssembly. We provide solutions for C/C++, Java, Flash and x86 native applications.
