What if I told you… your browser can do more than you ever imagined?

A while back, I set out to build a suite of developer tools that felt native, required no backend, didn’t depend on fancy infra, and could load faster than you can blink. Today, DevUtils.lol is exactly that.

This isn’t just another tool site. It’s a full-fledged offline-first PWA, entirely static, supercharged with WASM, and built to disappear into your workflow. Here’s how we made it feel like magic.

🧠 The Browser is the Backend

We chose to trust the browser. No SSR, no APIs. Just pre-rendered static pages and smart service workers. The result? Zero TTFB delay. Everything you see is shipped at build time, cached smartly, and controlled entirely by the browser. We leaned on:

  • Static site generation (Next.js export)
  • WASM-powered utilities (for crypto-heavy logic)
  • Runtime caching with smart fallbacks
  • A true offline experience that doesn’t scream “You’re offline!”

🦾 WASM = Native Speed, Web Edition

When you’re decoding a JWT, hashing strings, parsing base64, you don’t want JavaScript lag. So we compiled logic to WebAssembly — the secret sauce behind those snap transitions. It’s like using a power tool instead of a screwdriver.

📦 All Tools, No Server

From JSON prettifiers to encoders and token viewers, every tool is a self-contained browser app. Nothing ever leaves your device. You could unplug the internet and everything would still just work — because it was designed that way.

⚡ Instant Load. Everywhere.

The site weighs like a feather. Icons, splash screens, even install prompts are all tuned. First visit? Sub-second. Return visit? Served before your finger leaves the trackpad.

📲 One-Click Install. Then Vanish.

PWA install flows are usually annoying. Ours is the opposite: a single elegant prompt — only once — and it’s yours. After that, it lives like a native app. No Chrome tabs, no distractions. Just your tools.

💡 Devs Can Build Tools Too

Here’s where it gets exciting: DevUtils isn’t just ours — it can be yours too.

We’ve made it easy for you to build your own utility, and submit it to DevUtils to help other devs out. Whether it’s a tiny encoding helper, a regex debugger, or something totally fresh — if it runs in the browser, we can ship it.

Your tool could become a go-to for thousands of developers across the world.

All it takes is one great idea. And the rest… is pull request history.

💸 Zero Cloud Cost. Infinite Scale.

What happens when you remove the backend entirely? No infra, no database, no serverless functions. The site runs on GitHub + Cloudflare Pages. You could 100x traffic overnight — cost stays zero.

🛠️ Built With Passion, Runs With Peace

The goal was simple: build a developer utility platform that doesn’t feel like a product, but like a toolbelt you always have on. That never breaks. Never nags. Never leaks your data.

And now… it’s your turn.

🧪 Build Something for the Dev World

We’re opening DevUtils up to community-built tools.

Have an idea? Submit your tool or reach out. Let’s make tools that matter. Fast. Free. Forever.
