I built UtlKit because I was tired of tool websites that: Force you to create an account before using a basic JSON formatter Flood you with ads that make the actual tool hard to find Send your data to a server just to calculate a hash So I made something different. UtlKit.com has 150+ free tools across 11 categories: 💰 Finance — loan calculators, compound interest, ROI, Sharpe ratio, mortgage refinance 💻 Developer — JSON/YAML/SQL/XML formatter, regex tester, JWT decoder, HTML/JS/CSS formatter 📝 Text — case converter, diff checker, word frequency, find & replace, character counter, slug generator 🔄 Converter — base64, color, units, number base, morse code, hex/UTF-8, currency 🛡️ Security — password generator, hash (MD5/SHA), AES encrypt, HMAC, crypto liquidation price 🎨 Media — image compressor, QR code, gradient generator, palette, image resizer 🧮 Calculator — percentage, BMI, age, scientific, random, beta, odds converter 📅 Date & Time — unix timestamp, date calculator, pomodoro, reading time ₿ Crypto & DeFi — liquidation price, funding rate, staking APY, DEX Swap calculator 📈 Trading & Analysis — Pip calculator, Kelly criterion, maximum drawdown, position sizing, moving average calculator 📊 Valuaion — P/E & PEG calculator, P/E P/B valuation, market cap calculator, margin of safety calculator What makes it different: Everything runs client-side in your browser. No data leaves your device. No sign-up required. No tracking pixels. No ads. Built with Next.js 15, statically exported and hosted on Cloudflare Pages — zero server costs. It's the tool website I wish existed. Hope you find it useful too.
