is presented The experimental release of the operating system Capyloon built on the basis of Web technology and continuing the development of the Firefox OS platform and the B2G project (boot to gecko). The project develops Fabrice Desré, the former leader of the Firefox OS team in Mozilla and the chief architect of Kaios Technologies, developing Kaios, Filter Firefox OS. Among the main tasks of Capyloon, confidentiality is mentioned and providing the user to control the system and information. As the basis of Capyloon, the gecko-b2g , branched from the Kaios repository, is involved as the basis.
The source texts of the project spread under the AgPlv3 license.
First release is ready for use on smartphones Pinephone Pro, Librem 5 and Google Pixel 3a. A potentially platform can also be used on the first Pinephone model, but the performance of this device may not be enough for comfortable operation. Build available in Debian packages, Mobian environments (Debian version for mobile devices) and in the form of a basic system image based on Android. To install in Mobian and Debian, it is enough to install the proposed deb-package and run the B2GOS shell.
Setting can also be collected for installation on mobile devices supported by the KAIOS platform, to start in the emulator, to install on top of the Android platform based firmware and for use on stationary personal computers and laptops supplied with Linux or MacOS.
The environment is positioned as experimental, for example, while fully supported some of the functions important for smartphones, such as access to telephony to make calls, sending SMS and exchange data through a mobile operator, there is no possibility of control of audio channels, Bluetooth and GPS is missing. Partially implemented support Wi-Fi.
Capyloon applications are formed using the HTML5 stack and the advanced Web API program interface, which allows you to organize the access of Web applications to hardware, telephony, address book and other system functions. Instead of providing access to the actual file system, the programs are limited inside the virtual FS, built using indexeddb API and isolated from the main system.
The user interface of the platform is also built on the basis of Web technology and is performed using the GECKO browser engine. There are own configurators to configure the language, time, privacy, search engines and screen parameters. Capyloon specific features are noted using IPFS Protocol for Confidential Storage Data and Support Web Assembly Technology to Enhance Performance.
