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! 🙏

I saw there's theme support — how customizable is the look and feel?

ZTools takes themes seriously it's not just light/dark mode!

Here's what you can customize:

Light & Dark Mode the basics, done well
Color Customization adjust primary colors, accent colors, and UI tones to your preference
Extensive UI Settings control more than just the color scheme
Persistent your theme saves and loads every time you open ZTools
Synced sign in with Google and your theme preferences follow you across devices

I believe tools should feel like your tools. If you spend time in ZTools every day, it should look the way you want it to look.

What's the Product Finder feature? Is there a community aspect to this toolbox?

Yes! Product Finder is one of my favorite features because it turns ZTools from just a toolbox into a community-driven discovery platform:

Product Finder discover tools and utilities submitted by the community
Voting upvote tools you find useful, helping others discover the best ones
Comments share feedback, tips, and use-case ideas on tools
Admin Approval submissions go through review to maintain quality
Discovery find new tools you didn't know you needed

It's like a mini Product Hunt... inside a Product Hunt product!

The idea is that 484 tools is just the starting point. The community helps surface which tools matter most and suggests what should be added next.

Does ZTools work offline? I sometimes work in places with spotty internet.

Yes ZTools has PWA (Progressive Web App) support, which means:

Install it like an app add to your home screen or desktop from the browser
Offline-capable many tools work without internet once the app is loaded
Fast loading cached resources mean near-instant startup after first visit
No app store needed install directly from the web on any device
Auto-updates when you're back online, the app syncs to the latest version

Since most tools run entirely on client-side JavaScript, they don't need a server connection to process your data. That means tools like text formatters, calculators, encoders, and generators work perfectly even when your WiFi is being unreliable.

For the Android app, it's even better it's a native-wrapped Capacitor app with full offline tool access.
