Run In Playground is a Chrome extension developed by fraserhamiltonsoftware. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This free extension aims to enhance the coding experience while reading blog posts or experimenting with JavaScript code.

The main feature of Run In Playground is the ability to open code snippets in a code playground of your choice directly from the context menu.
