Rubic is a free Chrome add-on designed for prototyping with embedded boards using the Ruby programming language. It allows users to write Ruby scripts directly within its interface and execute them on connected boards with a simple click of the 'Run' button. The tool utilizes the mrubyengine for executing Ruby scripts on various supported embedded boards, making it accessible for both beginners and experienced developers. Currently, Rubic supports boards such as PERIDOT (Windows only), Wakayama.rb, and GR-CITRUS, providing versatility for different projects.

The user-friendly design of Rubic simplifies the prototyping process, enabling quick testing and deployment of scripts. Furthermore, it ensures user privacy by not collecting or transmitting any user-created sketches or usage statistics without explicit consent. This commitment to privacy enhances the overall user experience and trust in the tool.
