I built a free tool that roasts your website using AI. I launched it on the 4th of January, and so far 650+ websites have been roasted.

I built it using:

SvelteKit (frontend + small API requests) 3rd party screenshot API Azure OpenAI (gpt-vision) Loops (emails) Vercel (hosting + database)

I have a load of Azure credits so I hope this is a good way of giving back. It gives quite good feedback on quick things you can improve like CTAs, headlines and colour schemes etc. I hope you find it useful.

p.s. the only reason it needs an email is because of the queue system (api rate-limits), you'll receive a transactional (not marketing) email with the roast which you can then opt-out of any future emails, no data is sold, your pages are no-indexed so won't appear in search results. I do have a small banner in the email to cover some hosting costs (Vercel!), but this is a non-profitable resource :)
