A few tools, such as converting Word files to PDF, need a server, so those files are sent securely, converted and not stored.</p> <h2> What I used </h2> <ul> <li>Next.js and Tailwind CSS for the website</li> <li>Express and MongoDB for accounts and the contact form</li> <li>Gotenberg (LibreOffice) and a small Python service for the document converters</li> </ul> <h2> Try it </h2> <p><a href="https://seoanalyticslab.vercel.app" rel="noopener noreferrer">https://seoanalyticslab.vercel.app</a></p> <p>It is free and needs no signup. I would love your feedback, especially on which tool you would like to see next.</p> webdev showdev nextjs seo
