Dark Theme for link preview popups is now generally available. It's included in all usage plans, including Free plan. Linkz.ai dark theme looks equally great when your website has either light or dark background.
If your website has a light/dark mode toggle, you can use Linkz.ai "Dynamic Theme". Our script will automatically recognise which background your website has, and will display light or dark themed link preview accordingly. "Dynamic Theme" is available on the Website plan & higher.
