Here's the full list:</p> <ul> <li>JSON formatter/validator/minifier</li> <li>Base64 encoder/decoder</li> <li>JWT decoder</li> <li>Hash generator (MD5, SHA-1, SHA-256, SHA-512)</li> <li>UUID v4 generator</li> <li>URL encoder/decoder/parser</li> <li>Regex tester with match highlighting</li> <li>Unix timestamp converter</li> <li>Password generator</li> <li>SQL formatter</li> <li>Cron expression parser</li> <li>Markdown preview (GFM)</li> <li>Color converter (HEX/RGB/HSL)</li> <li>Text diff</li> <li>QR code generator</li> <li>Lorem Ipsum generator</li> <li>AI content detector</li> </ul> <p><strong>How it works:</strong> Everything runs client-side. You can open the network tab while using any tool — zero requests go out. Your data stays in the browser.</p> <p><strong>API:</strong> Every tool also has a REST endpoint. <code>curl -H "X-API-Key: your_key" https://usedevdash.dev/api/json -d '{"input": "{\"a\":1}"}'</code> returns formatted JSON. Free tier is 1,000 requests/day.</p> <p><strong>Stack:</strong> Next.js 16, Tailwind v4, Vercel. Static pages, no database for the tools themselves.</p> <p>If there's a tool you use daily that's not on the list, let me know.</p> webdev productivity javascript tooling
