Font Tester▲280I've been looking for new fonts to use for a new project, but there weren't any great tools for seeing how a particular serif font for headers would look with another sans font for paragraph text, so I built a tool that lets you compare, adjust, and tinker with the way you'd use a font in your specific project before downloading it/setting it up. This is only using the free Google fonts for now. If there are other open-source fonts I should add, let me know and I'll add them!
