No. TulBench uses privacy-focused Plausible Analytics for basic traffic stats only. This means:

• ✅ No cookies
• ✅ No personal data collection
• ✅ Fully anonymous aggregate stats
• ✅ GDPR/CCPA compliant
• ✅ We never see your IP address
• ✅ We never track individual users

We only see anonymous page view counts - nothing more.

No. All processing happens in your browser (client-side JavaScript). When you use a tool, your data never leaves your device.

You can verify this: Open your browser's DevTools (F12) → Network tab → Use any tool. You'll see zero network requests after the initial page load. Your data stays local.

Yes, but with context:

• ✅ Client-side processing: Your data never leaves your device
• ✅ No logging: We don't see or store what you input
• ✅ No tracking: Your usage is private
• ⚠️ Standard web security applies: Use HTTPS (we do), keep your browser updated
• ⚠️ Follow your org's policies: Some organizations prohibit external tools for classified data

For maximum security with highly sensitive data, consider running tools offline or using local alternatives.

No. TulBench uses zero cookies. That's why you don't see annoying cookie consent banners.

Our analytics (Plausible) doesn't use cookies either - it's truly cookie-free tracking.

Yes! TulBench is free for personal and commercial use. No attribution required (though we appreciate it!).

Thousands of developers use TulBench daily for client projects, enterprise work, and commercial applications.

Once a page is loaded, most tools work offline since processing is client-side. However, you need an initial internet connection to load the HTML/JavaScript.

For truly offline usage, you could save the HTML pages locally (right-click → Save As), though we don't officially support this.

TulBench works on all modern browsers:

• ✅ Chrome/Edge (Chromium) - Latest
• ✅ Firefox - Latest
• ✅ Safari - Latest
• ✅ Brave, Opera, Vivaldi - Latest

We use standard web APIs (no framework dependencies) for maximum compatibility.

Yes! All tools are fully responsive and work great on:

• 📱 iOS (Safari, Chrome)
• 📱 Android (Chrome, Firefox, Samsung Internet)
• 💻 Tablets (iPad, Android tablets)

Add tulbench.com to your home screen for app-like access!

Not currently. Since TulBench processes everything client-side, there's no backend API to access.

However, all our tools use standard JavaScript - you can view the source code and implement similar functionality in your own projects!

The tools themselves are not currently open source, but all the client-side JavaScript is visible in your browser (View Source).

We're considering open-sourcing the project in the future. Follow us on Twitter @tulbench for updates!

Most tools support standard browser shortcuts:

• Ctrl/Cmd + A: Select all text
• Ctrl/Cmd + C: Copy
• Ctrl/Cmd + V: Paste

Many tools also have a "Copy" button for one-click copying to clipboard.

No limits! Generate as many passwords, UUIDs, QR codes, or hashes as you need. Process as much data as your browser can handle.

Since everything runs client-side, there's no server cost to worry about.

TulBench is monetized through privacy-respecting advertising:

• ✅ Developer-focused ads (Google AdSense)
• ✅ No invasive tracking
• ✅ No personal data sold
• ✅ Minimal, non-intrusive placement

This keeps the tools free for everyone while respecting your privacy.
