GitHub Issue Link Status is a free Chrome extension developed by fregante. It falls under the category of Browsers and the subcategory of Add-ons & Tools. This extension allows users to colorize issue and pull request links on GitHub to indicate their status, whether they are open, closed, or merged.

One of the main features of GitHub Issue Link Status is its use of GraphQL to make a single HTTP request to check all the links on a page at once. To use this extension, users are required to create an API token and add it to the Options page. Without the API token, the extension will not function properly.

Furthermore, GitHub Enterprise is supported by this extension, providing users with additional options and functionality. For more information on how to use this feature, users can refer to the options provided.

Overall, GitHub Issue Link Status is a useful Chrome extension for GitHub users who want a visual representation of the status of issue and pull request links on the platform.
