How to test Tribute Page when not using CodePen

I don’t like CodePen and don’t feel like paying for it. Free version tells me I already used my one project.
I prefer to use Visual Studio Code. How do I test my project? There is no explanation given.

Just copy the script (<script src="https://cdn.freecodecamp.org/testable-projects-fcc/v1/bundle.js"></script>) into your HTML code placing it before the closing body tag.

As an aside, I don’t think anyone here is paying for codepen. Create a pen, not a project. You can create many different pens with no charge.

I use codesandbox.io because I think it’s way better and almost as good as VSC for front end development. Anyway, you can just put this into your body or add the URL as a dependency and you’ll be good to go!
