ScraperWiki-Gist is a Chrome add-on developed by Ross Jones. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This free software allows users to run code from Gist, a code-sharing platform, directly on the current webpage.

With ScraperWiki-Gist, users can easily test out code snippets from Gist without leaving the page they are currently on. When viewing a Gist, a cog icon will appear in the address bar. By clicking on this icon, users can execute the code and see the results instantly. However, it's worth noting that not all programming languages are supported, and incomplete or code that relies on external libraries may not work as expected.

Overall, ScraperWiki-Gist provides a convenient way for developers and programmers to quickly test and run code from Gist without the need for additional tools or platforms.
