Kobo can run apps now
TL;DR
Kobo e-readers can now run apps through Cobalt, an open-source platform that allows users to install and manage applications directly on their devices. This development enhances the functionality of Kobo devices while maintaining a secure environment for app execution.
✦ Why It Matters
Install Cobalt on your Kobo today to expand its capabilities with custom applications.
Key Takeaways
- Install Cobalt once via USB to enable app functionality.
- Use the Rust SDK to develop apps for Kobo devices.
- Apps can be installed and updated directly over Wi-Fi.
- Ensure app signatures are verified for security before execution.
How It Works
Cobalt operates by allowing each app to run in its own unprivileged process, ensuring that they do not interfere with each other or the core system. The Rust SDK provides a framework for developers to create apps that can request access to device resources like network and storage, which are managed through capability gating.
This means apps must explicitly ask for permissions, enhancing security and user control.
