How we build

Rust, on our own platform.

Most of our code is Rust: the Sylphx platform, Keel Engine and the open-source tools.

Every product runs on Sylphx itself, so the platform gets used every day by the people who build it.

Keel Engine is proprietary and licensed to teams by agreement. The developer tools are open source under the MIT licence.
