DevDash: 17 dev tools, one URL, all client-side

I put together a set of browser-based developer tools at usedevdash.dev. Here's the full list:

• JSON formatter/validator/minifier
• Base64 encoder/decoder
• JWT decoder
• Hash generator (MD5, SHA-1, SHA-256, SHA-512)
• UUID v4 generator
• URL encoder/decoder/parser
• Regex tester with match highlighting
• Unix timestamp converter
• Password generator
• SQL formatter
• Cron expression parser
• Markdown preview (GFM)
• Color converter (HEX/RGB/HSL)
• Text diff
• QR code generator
• Lorem Ipsum generator
• AI content detector

How it works: Everything runs client-side. You can open the network tab while using any tool — zero requests go out. Your data stays in the browser.

API: Every tool also has a REST endpoint. curl -H "X-API-Key: your_key" https://usedevdash.dev/api/json -d '{"input": "{\"a\":1}"}' returns formatted JSON. Free tier is 1,000 requests/day.

Stack: Next.js 16, Tailwind v4, Vercel. Static pages, no database for the tools themselves.

If there's a tool you use daily that's not on the list, let me know.
