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

I'm trying to use this "SD > Vector image" model. (linked here) To do so, I must have "potrace" installed. (linked here). Source: 10 months ago

As the author mentions PNG to SVG conversion, there is Potrace [1]. I think you need to convert to BMP before. It's a pretty nice tool. I have used it a couple of times. [1] https://potrace.sourceforge.net/. - Source: Hacker News / 10 months ago

The answer to your question is Potrace. There's probably a wrapper API available for whatever language you're using (presumably Python), or you can simply run it as a command line tool. Potrace is used behind the scenes for image tracing in Inkscape, the most popular open source vector design app, and I've also seen it used in a plugin someone built for Stable Diffusion/A1111 that does exactly what you're trying...

This is generally rather computationally expensive, but I believe you are looking for potrace. Source: over 1 year ago

For fairly simple art, you could try potrace: http://potrace.sourceforge.net. Source: almost 2 years ago
