I wanted something that works <br> entirely in the browser.</p> <p>So I built <strong>Wrklyst</strong> — a growing collection <br> of free utility tools that process files locally <br> using WebAssembly. Your files never leave <br> your device.</p> <h2> What's Inside </h2> <ul> <li> PDF tools (merge, compress, convert, sign)</li> <li> Image tools (convert, compress, resize)</li> <li> Writing tools (word counter, grammar checker)</li> <li> Developer tools (JSON, regex, base64)</li> <li> Security tools (password generator, hash)</li> </ul> <p>More tools dropping every week </p> <h2> Tech Stack </h2> <ul> <li> <strong>Next.js 16</strong> — App Router</li> <li> <strong>WebAssembly</strong> — browser-side processing</li> <li> <strong>Vercel</strong> — deployment</li> <li> <strong>Supabase</strong> — database</li> <li> <strong>Tailwind CSS</strong> — styling</li> </ul> <h2> The Privacy Angle </h2> <p>Most online tools upload your files to a server.<br> Wrklyst processes everything locally — meaning:</p> <p>No file uploads<br><br> No account needed<br><br> No paywalls<br><br> Always free </p> <h2> Still Building </h2> <p>This is an early version — still growing and <br> adding new tools regularly. Would love your <br> honest feedback.</p> <p><a href="https://wrklyst.com/" rel="noopener noreferrer">wrklyst.com</a></p> <p>What tool do you wish existed? <br> Drop it in the comments! </p> ai webdev programming productivity
