Cloudlink is a free Chrome extension designed to enhance Scratch 3.0 projects by allowing users to link cloud variables from one project to another. This add-on is particularly beneficial for developers who want to share data between their Scratch projects effortlessly. The extension is easy to install and use, providing a streamlined process for remixing and modifying projects while maintaining cloud variable connections.

To utilize Cloudlink, users simply need to install the extension, navigate to any Scratch or TurboWarp project, and remix it. After making desired modifications, users can copy the original project link and use the Cloudlink button to paste it. This functionality helps facilitate collaboration and data sharing within the Scratch community, although users are advised to note that cloud variables may currently be down, and alternative solutions like TurboWarp should be used in the meantime.
