photon

Photon is a UI toolkit for building desktop applications with Electron, a framework that lets developers create desktop software using web technologies like HTML, CSS, and JavaScript. Photon's job is to supply the visual layer: a stylesheet and a set of fonts you drop into your project so your app looks polished without you having to design the components yourself.

The download package includes a compiled CSS file, a set of Entypo icon fonts, and a template Electron application that gives you a working starting point. You clone the repository, pull in the CSS, and your app inherits a consistent, native-looking interface. The documentation, hosted at photonkit.com, walks through the available components and explains how to wire them into a new project.

For developers who want to modify the styles rather than just consume them, the project uses Sass source files. Running the build command compiles those files down to the final photon.css. The docs site is built with Jekyll and can be run locally for contributors who want to preview documentation changes before submitting them.

Photon follows semantic versioning, where the version number signals whether a release contains breaking changes, new additions, or just small fixes. The master branch is the active development branch and may be unstable; the tagged releases are the stable copies to use in production.

The project is maintained by Connor Sears and released under the MIT license. Bug reports go through GitHub Issues, and a contributor guidelines document explains the expected format for reports. The README does not describe a paid tier or a hosted service; this is a standalone toolkit you run locally inside your own Electron project.
