Hey Product Hunt! 👋 I'm Ahsan, and I built ZTools because I was tired of the same daily cycle: need to format some JSON → Google "JSON formatter online" → land on a random site → paste my data → hope they're not storing it → repeat for the next task. ZTools puts 484 of those tools in one place. And here's what makes it different: 🔒 Privacy-first — everything runs client-side. Your data literally never touches a server. No "trust us" disclaimers needed because there's no server to send data to. 🧰 Real product depth — this isn't just a page of tools. There's smart search, favorites, collections, presets, history, theme customization, and a community-driven Product Finder where users can vote and discuss tools. 📱 Multi-platform — same 484 tools on web, Android (Play Store), and as a Chrome/Firefox extension for quick toolbar access. ⚡ Fast — React 19 + Vite 7, code-split so tools load on demand. 201 automated tests keeping everything stable. 🆓 Free — no paywalls, no "upgrade to unlock tool #21." All 484 tools are available. Optional Google sign-in for syncing favorites across devices. Some categories people love most: • Code tools (JSON, regex, minifiers, encoders) • Text tools (case converters, counters, diff) • Design tools (color pickers, gradients, CSS) • Calculators & converters (units, currency, time zones) • Generators (passwords, UUIDs, QR codes, lorem ipsum) I'd love to hear: what's the one utility tool you Google for most often? If we don't have it yet, I'll add it. 🚀 🔗 Try it: https://ztools.zaions.com 📱 Android: Search "ZTools" on Play Store 🧩 Extension: Search "ZTools - Utility Tools" on Chrome Web Store Thanks for checking it out — happy to answer any questions! 🙏

How does ZTools handle privacy? Do my files and data get uploaded to any server?

This is probably the thing I'm most proud of about ZTools your data never leaves your browser.

Here's the privacy model:

Client-side processing the vast majority of tools run entirely in your browser using JavaScript
No server uploads your files, text, code, and data are never sent to any backend
No data collection on tool usage we don't track what you paste, convert, or generate
No account required most tools work without signing in at all
Google sign-in is optional only needed if you want features like favorites sync and collections
Works offline PWA-capable, so once loaded, many tools work without internet

I built ZTools because I was tired of pasting sensitive JSON payloads and API keys into random websites that "promise" not to store them. With ZTools, there's literally no server to store them on it all processes locally.

Is there a mobile app or is this web-only? I'd love to have tools on my phone?

Great news ZTools is available on Android too!

Here's where you can use ZTools:

Web App full experience at https://ztools.zaions.com, works on any browser
Android App available on Google Play Store (search "ZTools" by Zaions)
Browser Extension Chrome Web Store ("ZTools - Utility Tools") for quick access from any tab
PWA Support install from the browser for a native-app-like experience

All three surfaces share the same tool library, so you get the full 484 tools whether you're on desktop, mobile, or using the extension. Your favorites and settings sync across devices if you sign in with Google.

What does the browser extension do? Is it just a link to the website?

Definitely not just a link! The extension is built as a standalone quick-access companion:

Instant tool access open the extension popup and use tools directly without navigating to the site
Search from your toolbar find any of the 484 tools right from the extension icon
No new tab needed run quick conversions, formatting, or generation without leaving your current page
Same tool quality uses the same client-side logic as the web app
Chrome & Firefox built for both browsers with a custom build system

It's designed for the "I need this tool for 10 seconds" moments. You're coding, you need to quickly base64-encode a string pop open ZTools, paste, done, back to work. No context switching.

"The fastest tool is the one that's already in your toolbar."
