I just shipped two more developer tools on EveryTool — and both are ones I personally kept Googling repeatedly before finally just building them properly.
🔑 UUID Generator
Need a UUID? Most devs just search "UUID generator online," click the first result, and hope it's not doing something sketchy with the output.
The EveryTool UUID Generator:
- Generates v1 (time-based) and v4 (random) UUIDs
- Supports bulk generation — need 50 at once? Done.
- Copy to clipboard in one click
- Runs entirely client-side using the native
crypto.randomUUID()API — nothing leaves your browser
No tracking. No ads. No "sign up to generate more."
⏰ Cron Expression Builder
Cron syntax is one of those things that never fully sticks. Is it 0 9 * * 1 or * 9 0 * 1? I always end up on crontab.guru double-checking.
The EveryTool Cron Expression Builder offers:
- A visual field-by-field builder (minute, hour, day, month, weekday)
- Human-readable preview — see exactly what your expression means in plain English
- Real-time validation so you catch errors before they hit production
- Common presets (every hour, every day at midnight, every Monday, etc.)
Again — fully client-side, no backend involved.
Why client-side only?
EveryTool is built on a single principle: your data doesn't leave your browser.
No file uploads to a server. No accounts. No usage tracking. Just tools that work, fast, in your browser tab.
The stack is Next.js App Router + TypeScript + TailwindCSS, deployed on Vercel. For cryptographic operations like UUID generation, I use the Web Crypto API directly rather than pulling in an external library.
Where things stand
We're now at 33+ tools across four categories:
- 🖼️ Image Tools
- 📄 PDF Tools
- 🧮 Calculator Tools
- 🛠️ Developer Tools
Developer Tools is the most active area right now. Recent additions include Base64 Encoder/Decoder, URL Encoder/Decoder, Hash Generator, JWT Decoder, Regex Tester, and Color Code Converter.
What's next?
I'm continuing to expand the Developer Tools category. If there's a tool you constantly Google or find yourself copy-pasting from Stack Overflow, let me know in the comments — it might be next on the list.
