QuietBench: A Free Developer Utility Suite I Built Solo (No Ads, No Sign-Up, No BS)

What I Built

QuietBench (quietbench.dev) is a free suite of everyday developer utilities - the kind of tools you Google at 2am when you're stuck on something small but annoying:

• JSON Formatter - format, validate, and minify JSON instantly
• Regex Tester - test patterns with live match highlighting
• Cron Builder - build and understand cron expressions without memorizing syntax
• WCAG Contrast Checker - check color contrast ratios for accessibility compliance
• API Request Tester - send requests and inspect responses without opening Postman

No accounts. No paywalls. No cookie-consent maze. Just open the tab, do the thing, close the tab.

Why I Built It

I kept bouncing between five different single-purpose tool sites every time I needed to format JSON or test a regex - each with its own ad-heavy layout, weird UX, and a sign-up wall for "advanced" features I didn't need. I wanted one clean, fast place for the tools I reach for constantly. So I built it.

Tech Stack

• React + Vite + TypeScript for the frontend
• Tailwind CSS for styling
• Cloudflare Pages for hosting
• Porkbun for the domain

The whole thing is a static SPA, deployed with a single command:

npm run deploy

which runs the Vite build, prerenders every route, and pushes to Cloudflare via Wrangler.

Challenges I Ran Into

A CSP regression that tanked my LCP score

I tightened my Content Security Policy for safety and accidentally forgot to allowlist Google Fonts. Page load time (LCP) spiked overnight. Lesson: every CSP change needs a Lighthouse re-check, not just a "looks fine" glance.

SPAs and crawlers don't get along

Since QuietBench is a client-rendered SPA, non-JS crawlers (and some bots) were seeing an empty shell instead of actual content. I fixed this with build-time prerendering using Playwright - every one of the 11 routes now gets a fully-rendered HTML snapshot generated at build time, so crawlers see real content without needing to execute JS.

Getting indexed without SEO gimmicks

Rather than chasing broad, competitive keywords, I focused on long-tail, exact-match queries - specific error messages, exact syntax terms, the kind of thing someone pastes directly into Google when they're stuck. I also set up IndexNow for instant Bing submission on every deploy, so new content doesn't sit around waiting to be crawled.

The little things that break silently

A www/non-www redirect inconsistency was quietly splitting my traffic and confusing search engines - fixed with a Cloudflare Redirect Rule. Small, boring, but it matters for SEO hygiene.

What's Next

• Two more long-tail content pages, currently paused while I read Search Console data to make sure I'm building the right pages, not just more pages
• Continued distribution - dev.to has been the most genuinely engaged channel so far
• More utilities based on what I personally keep needing

Try It

👉 quietbench.dev

It's free, it's fast, and it doesn't ask you for your email. Would genuinely love feedback from other devs - especially if a tool is missing something you'd expect, or if you spot a bug. Building this solo, learning SEO and infra as I go. If you're into indie dev tools or want to swap notes on prerendering/IndexNow setups, drop a comment - happy to share specifics.
