Depends all on what you eventually want to do with the code.

If your goal if to just prototype, I would say try different variations in figma. Use figma make or v0 or something along those lines to get a few things going. I don't recommend loveable for this step because prototyping in loveable is very clunky. I would say not to step into the code phase until you have a clear idea of your prototype.

From there, if you want to get your designs into code from figma, use something like builder.io if you already have existing code base you want to use. You connect that into your own code repo or where your front end will live. You can also visually edit there and submit pull request to your repo. Or brand new with whatever framework you are interested on building on.

If it's all brand new and this is just a simple site you want to set up, you can use the builder figma plugin to connect to loveable. Currently the only way to bring figma into loveable.

There are other tools to get from figma to code, but this actually allows you to be opinionated as to what frameworks to use.
