Diptyx is a new open-source e-reader now crowdfunding on Crowd Supply, positioning itself as a long-term alternative to locked-down commercial devices. Built around an ESP32 microcontroller and a distinctive dual-screen design, the device focuses on ownership, repairability, and offline reading without DRM or cloud dependencies.

The most striking aspect of Diptyx is its book-like form factor. Two 5.83-inch black-and-white e-ink displays are joined by a hinge, allowing the device to close like a physical book and protect the screens without requiring a case.
