CG Overlays is a free Chrome add-on developed by xoposhiy that aims to enhance the Codingame experience by allowing users to create their own overlays in the visualizer. This add-on is specifically designed for the Codingame.com IDE and replay page.

With CG Overlays, users can utilize their bot's stderr output to create instructions that will be interpreted as overlays on the CG game visualizer. This feature opens up a whole new world of possibilities for developers, enabling them to visualize their bot's behavior in a more interactive and engaging manner.

The add-on is easy to install and use, seamlessly integrating into the Codingame platform. Whether you're a beginner or an experienced programmer, CG Overlays provides a unique opportunity to showcase your coding skills and bring your creations to life.
