The Manifold platform consists of two primary components—the client application and the API—and a few complimentary microservices. It is offered as a managed OS packages, Docker images, and paid hosting services. The API is Ruby on Rails and the client app is React.

Cast Iron Coding developed the Manifold platform based on designs created by Lael Tyler. Monifold books open in a flexible book reader that can contain media links, interactive notes, and annotations (highlighting and inline commenting). The reader itself is user-customizable; an appearance menu can change the color scheme, font text size, all without losing your place in the book.
