I built a collection of 34 developer tools that run entirely client-side — no backend, no accounts, no data collection.
- JSON/SQL/YAML formatters, Base64, URL encoder, Hash generator (Web Crypto API)
- CSS visual tools: gradient, box-shadow, text-shadow, border-radius generators
- Image compressor (Canvas API), SVG to PNG, color palette generator
- Regex tester, JWT decoder, chmod calculator, cron builder, diff checker
- Password generator using crypto.getRandomValues (not Math.random)
Stack: Next.js 15 (SSR for SEO), TypeScript, Tailwind CSS v4. Near-zero npm dependencies — custom SQL tokenizer, custom markdown parser, custom LCS diff algorithm.
