Hey there. You can always use the Angle plug in https://angle.sh/ it is free both for figma and sketch but it also a paid version I personally use the free. It is more than enough. Source: almost 2 years ago

There’s a handful of plugins you can find to apply your designs to mobile mock-ups like this. If you want professional ones, I’ve found Angle to be top tier, the full library is a little pricey, but worth it if you have the need. Source: over 2 years ago

They do cost money unfortunately, but what you could do is use a tool like https://whimsical.com/wireframes to wireframe your website (free if you keep all files in your personal folder). Then use tailwindui or flowbite as a reference (or some other template library) while wireframing, skip the mockup stage, and then go straight into the coding phase? Source: 11 months ago
