SELECT EXPERIENCE_
Both products share the same Veyllisto design philosophy, interface system, and library foundation. The difference is where Veyllisto lives.
Run the Veyllisto experience on the computer you already use. Keep Windows, Linux, or macOS underneath while Veyllisto handles the front-end experience.
A dedicated operating environment designed for systems where Veyllisto is the entire experience — ideal for purpose-built machines, living-room systems, and appliance-style hardware.
The Interface Engine and Veyllisto OS are not separate ideas. They are two deployment paths for the same underlying experience: a unified library, interchangeable shells, guided configuration, physical-media behavior, and a deliberately cohesive visual and audio identity.
The J-29 Terminal is one shell within that ecosystem — not the limit of what Veyllisto can become.
