Built on top of GitHub’s Electron framework for cross-platform desktop apps, Quark is a general purpose tool that leverages JavaScript, CSS, and HTML.

Electron has patched the remote code execution vulnerability in the latest versions of the framework, and is urging developers to update their applications.

Recently, JavaScript founder Brendan Eich cited Electron as a tool his new company, browser maker Brave Software, has used in building its technology. Version 1.0 is available at electron.atom.io.
