Hi, I just build an open source project, convertfast-ui providing landing page blocks you can copy paste to your project. All code blocks are based on shadcn and tailwind. Convertfast-ui also provides a CLI tool, with some quick command to generate landing pages directly into your project, a command example would be:

npx convertfast-ui@latest page create <my-page>

It will generate landing page code in my-page and then you can edit them for customization.

Feedback and suggestions are welcome.

It's a free and open source project, the landing page demo is a showcase not real product.
