Built by an organ builder, for organ builders

KTESIBIOS is the modern successor to a legacy desktop application that has been used to design windchests in shops across Europe for nearly three decades.

From legacy to cloud

The original application dates back to the early 1990s as a desktop program for organ builders. KTESIBIOS preserves the same pipe-spacing mathematics that organ builders have trusted for decades, while replacing the desktop program with a browser-based workspace that any modern shop can share.

The official Ktesibios

Ktesibios is the official continuation of the windchest design program previously offered by Technical Software Design at ktesibios.com. It is now developed and published by Cornado LLC at ktesibios.app. If you used the original program, this is its new home — your projects and files are welcome here.
