Cashel Builders
Build apps other businesses own
Cashel is a platform other businesses run their apps on. You sign your work with a free Keystone pass. An unsigned app never installs on a customer’s machine.
Builder accounts, the toolkit and the marketplace remain in build
The Keystone pass
The Keystone is the stone that locks an arch. Yours is free. You sign your app with it, and a customer’s machine checks that signature before the app is added. That check is what lets a business trust an app it did not write.
The programme

Sold once, owned by the buyer
Apps are sold the way Cashel itself is sold: bought once, owned by the buyer, priced by the builder within fair bounds.
Signed, or it does not run
Every app carries a builder’s signature. An unsigned app never installs on a customer’s machine.
Built by you, by name
Listings say “Built by” and your verified name. No signup fee.
Later: games and 3D tools on the same platform. Cashel Games is on the roadmap.
One toolkit
The same building blocks Cashel’s own apps use, so an app from an independent builder feels like part of the same product.
The builder guides are not on this site. They come with your builder account when accounts open.
Still in build
Accounts, the public toolkit and the marketplace are not for sale yet.
