About YourDevTools

Every developer has a folder of bookmarks for ad-riddled, slow tool sites that show three modal dialogs before letting you paste a JSON snippet. We got tired of it. YourDevTools is one place for the small utilities that come up a dozen times a day: formatting a response, encoding a file to base64, generating a UUID, building a QR code for a handout, validating a sitemap.

Mission

Build a fast, broad, polished home for the long tail of developer and everyday utilities, in two languages, with privacy as a default rather than a feature.

What we believe in

  • Privacy by default. Most tools never send your input anywhere; they run in the browser. The ones that need a server process your input in memory and drop it on the floor as soon as the response is returned. Aggregate analytics is on; advertising and Google Analytics 4 are off until you grant consent.
  • No ads in the way of work. When ads do appear in the future (to keep the lights on), they will live in clearly separated areas of the page and never interrupt the input-output loop.
  • Speed. A tool should open in under 200 ms and respond instantly. We split bundles per tool, ship server-rendered HTML for the chassis, and avoid heavy hydration where simple HTML works.
  • Breadth. Cover the long tail (cron expressions, JWT debugging, color palettes, regex testing, mortgage calculators) in one place, so you stop hunting through three different ad-laden sites for a 30-second task.
  • Polish. No popups, no upsells, no ad walls between input and output. Keyboard-friendly, dark mode, accessible.

What we are not

  • We are not a SaaS. There are no plans, no upgrade buttons, no premium tier.
  • We are not a paid service. Everything is free; the only thing we ask is that you do not abuse the rate limits.
  • We are not a tracking-heavy site. But to be honest, we do measure aggregate traffic with Umami (cookieless, no consent needed) and an internal events warehouse, so we can see which tools people actually use and which ones are broken. If you enable Google Analytics 4 or accept marketing cookies, those run too. The Privacy Policy describes the full picture.
  • We are not a substitute for a qualified professional. Use the tools, then verify the output before relying on it for anything important.

Roadmap

The catalogue has more than 300 tools today and grows when we spot something we needed and could not find elsewhere. Planned additions include more financial calculators, more identity-and-crypto debug tools, and richer offline support. We will also enable a small amount of contextual advertising via Google AdSense at some point, gated behind explicit consent, so the project can pay for its own hosting.

Tech stack

  • Next.js 16 on the App Router with React 19
  • TypeScript in strict mode with noUncheckedIndexedAccess
  • Tailwind CSS v4 with an OKLCH-based design system
  • next-intl for the PL / EN split
  • Vercel (EU region) for hosting

The site code follows the security baselines listed in the Privacy Policy: HSTS, per-request CSP nonces, SSRF guard on outbound fetches, DOMPurify on HTML rendering, Web Crypto API throughout. Audits and changelogs live in the audits/ folder of the repository.
