Cobalt Brings Installable Apps to Kobo E-Readers
Cobalt adds app installs to a device built for reading without replacing Kobo's boot chain, so books and reading settings stay intact and a reboot returns the reader to stock behavior.
Reporting from 1 source: GIGAZINE.
BandarLabs released Cobalt, an open-source application platform for Kobo e-readers, built around a launcher, a catalog of signed apps, a Rust SDK, and a runtime that runs each app in an independent, unprivileged process. Apps are installed and removed individually over Wi-Fi. Seven Kobo models have been tested so far, including the Clara BW, Clara Colour, Elipsa 2E, and Libra Colour.
Cobalt runs apps in an independent, unprivileged process, and its catalog covers reading, feed subscriptions, games, audio listening, and task checking. Developers build with a Rust-based SDK, deploy to a Kobo, and submit to the store; users install, update, or remove single apps over Wi-Fi rather than flashing a whole image. The interface is designed around e-ink limits, with large touch targets, readable text, and full refreshes only when the panel calls for them. Installation runs from a browser and terminal.
